3 Why not benefit from the market leader s experience All over the world, cities are confronted with the challenge of meeting mobility needs, accommodating increasing traffic volumes on road networks that can usually not be expanded, and complying with the population s right to clean air at the same time. No easy task! We are proud to count among the most sought-after partners for traffic engineering solutions all over the world. Siemens has played a decisive role in the history of traffic engineering and infrastructure. As global market leader, we can rely on the unique wealth of nearly 100 years of experience in realizing efficient technologies and solutions. We have already designed and built more than 1,000 traffic centers all over the world more than any other company. This unrivaled expertise has enabled us to build our traffic control center platform in its current form and we will continue to benefit from it for future developments. What makes our traffic centers outstanding: They are highly flexible, scalable, open and easy to use. At the same time, our customer-centered innovation management ensures that new components can be smoothly combined with existing equipment and systems an important contribution to the sustainability of your investments. 3

4 Functions & interfaces A scalable platform that meets individual requirements By developing Sitraffic Concert, Sitraffic Scala and Sitraffic Guide we have created a traffic center platform that integrates the hitherto separate worlds of traffic management, traffic control and parking guidance. Our new Sitraffic traffic center platform is based on a simple idea: The function modules run on a shared basis and can be expanded or combined at any time with further modules. This allows the successive realization of a wide range of scalable applications, from entry-level solutions for a limited number of field devices right up to complex, integrated traffic management systems, in step with the city s budget and changing demand. All modules of our end-to-end traffic center platform use a shared data pool. This makes the different traffic planning and control tasks easier and saves time because it eliminates the need for multiple data entries and potential error sources. Another advantage of the shared platform is the uniform user interface used for different applications. And thanks to their standardized communication interfaces, all Sitraffic systems can be smoothly linked up with existing technical installations. For the municipal authorities this means maximum investment security because any installed traffic infrastructure remains operational. Our new user interface mimics the workflow in the traffic center for each application and can be flexibly configured to fit the requirements of specific tasks. This makes our traffic center systems intuitive and easy to use, providing the operator with all important information at a glance. 4

6 Modularity allows customized solutions For all central applications, the Sitraffic traffic center platform uses a common basis for the operation of the function modules for traffic management, traffic control, parking guidance, traffic planning and link-up with third-party systems. All modules are fully synchronized with each other and access a shared data base so that maximum transparency and consistency are guaranteed. Since the function modules can be combined across different traffic applications, the user is offered the necessary flexibility to implement individual, customized solutions no matter if the desired functions belong to the traffic computer landscape or are part of traffic management. On the following pages you will find the description of the most important function modules. A fully integrated modular system...

7 1 Schedules and locations for planned roadworks can be taken over from the data base of the responsible public body 2 Internet-based information platforms such as Verkehrsinfo Bayern receive their data from different traffic centers 3 Solar-powered or conventional Traffic Eye Universal (TEU) infrared detectors record key traffic data 7

8 Sitraffic traffic center platform: Basic modules Operational monitoring This module continually receives and processes operational and status messages from all connected sensors, actuators and subsystems. In case of a failure or fault, the system provides structured and where appropriate automated procedures for efficient message processing, secure archiving and immediate forwarding of fault messages to service technicians, if required. The goal is to initiate the fault clearance process as soon as possible. GIS map The user interface is equipped with a digital vector map, which shows all objects including their static and dynamic data on a city map. The objects are organized in layers that can be displayed and hidden as desired. This convenient function enables the user to monitor the current traffic situation as well as the operational status of all field devices and to carry out operator control actions directly from the map. Data management This module creates the foundation for meaningful statistics, historic reports and traffic planning analyses. A range of raw and aggregated data (measured values of various types) from different sources are permanently stored in the measuredvalues archive following plausibility checks, standardization and, if required, the generation of substitute values. Highly secure Web-based operation (CWP Customer Web Portal) The Customer Web Portal allows the safe operation of the Sitraffic traffic centers via an Internet connection and a standard Web browser. Password protection and mobile PIN assure the highest industrial security level. 8

9 Sitraffic Scala: Modules for traffic control Sitraffic Office: Planning and data supply of traffic signals Sitraffic Office is the first completely integrated software system for all applications in the area of traffic signal installations, from planning to data supply for traffic computers and controllers including the corresponding traffic actuation in Sitraffic PDM(e) or Sitraffic SL(e) for intersections right up to the model-based adaptive network control system Sitraffic Motion. Sitraffic Office provides planners, software engineers, operators and service technician with all required tools with direct access to the shared data base. The integrated administration and versioning functions are setting new standards in terms of process quality. Data consistency is one of the features that make Sitraffic Office unique because it eliminates the need to enter data more than once and substantially reduces the risk of errors. For instance, planning data are directly available for simulations and can also be used as the basis for device-specific additions without double entries, redundant data sets or inconsistencies. Further advantages offered by the central data pool are the integration of intersection, link and network planning as well as the possibility for several users to work on the same project at the same time. Sitraffic TASS for situation-actuated signal program selection TASS (Traffic-Actuated Signalplan Selection) is based on a predefined set of recurrent traffic situations such as High inbound traffic volumes or Stadium access, each of which has been assigned an optimal signal plan. The automatic recognition of the current traffic situation requires a strategic detection system. Threshold values and specific algorithms allow the identification of the current situation and the subsequent activation of the associated signal plan. The integration of environmental values allows the implementation of environment-related traffic control measures. Sitraffic Motion for model-based, traffic-actuated signal control Sitraffic Motion MX (Method for Optimization of Traffic in Online Networks) uses measured values to assess the current traffic situation, and innovative algorithms to calculate the optimal signal programs to be sent to the relevant traffic signal installations. All tasks related to the network are carried out on the central control level. As traffic flows are optimized on both the local and the central level, the system can react very quickly and effectively to any changes in the traffic situation, even in case of strong fluctuations in traffic load. Sitraffic Motion is also a useful tool when it comes to environmental protection: The dynamic adaptation of coordinated green phases (Greens Waves) during morning and afternoon peak hours has a substantial measurable effect on fuel consumption and emissions. Quality management This module monitors traffic signal switching states and parameters such as waiting times upon pedestrian or vehicle green requests, as well as travel times of public transport vehicles. Values in excess of predefined thresholds are indicators of deteriorating traffic sig nal switching quality. The detailed quality analyses available in the module make targeted improvement measures possible. Visualization The visualization function serves to display current and historic switching states of individual traffic signal installations, including their coordinated green phases. With this tool, the signaling state at a specific moment in the past can be verified, for instance for a detailed analysis of traffic-actuated control processes. Statistics Sitraffic Statistics offers comprehensive options for the statistical analysis of data from all connected sensor types. Statistical reports include lists and graphs such as peak hour patterns, flow-concentration diagrams, daily time graphs or annual time graphs of daily traffic volume fluctuations. 9

10 Sitraffic Concert: Modules for integrated traffic management Traffic situation detection The detection and visualization of the current traffic situation is a key element in the operation of any traffic management center. The traffic situation detection tool collects, checks and analyzes data from various sources. Due to our thorough traffic engineering experience and knowhow, we know exactly how to turn the measured values into useful information for the operators in the center and the connected control and information systems. Incident management Not all data relevant for traffic control can be detected automatically. To round out the data base, additional trafficrelated information needs to be entered, edited and completed via a traffic information editing workstation. Traffic news generated on the basis of detector data, for instance, can be supplemented with directions provided by the police or information on certain additional factors such as planned major events. For roadworks management, the system can automatically take over relevant geographical data from the road authority s data base into the traffic data base. The information entered via the traffic information editing workstation is a factor in the definition of suitable traffic management measures, such as general strategies, alternative route suggestions and adaptive network control, and is used for travel time calculation and road user information. Data fusion In general, the data used for the description of the current traffic situation come from multiple sources and differ in terms of content, geographical detail, provision interval and quality. The fusion of these data will help enhance overall data quality, for instance in terms of completeness, accuracy and updating frequency for optimized traffic control, traffic guidance and traffic information. Meaningful data fusion includes the evaluation of data reliability and takes the specific characteristics of the applied detection technologies into account. For this purpose, Siemens is developing requirements-based, tailored solutions in the scope of current projects. Strategy management The strategy management module serves to define the general control strategies according to which the different systems and processes will work. The tool retrieve all measured values, status information and operational messages available in the system, matches them with user-definable threshold values and combines them with time constraints to define effective traffic interventions. Urban traffic data and data from surrounding speedways as well as parking, environmental and other situational data can be combined in logical sequences as needed. The defined strategy is the foundation for the implementation of various measures such as Green Waves, dynamic direction signs or road user information using a range of media. Travel times New technologies and processes enable the direct recording of route-related data, in particular travel times. Such data are often a much more precise indicator of congestion and traffic disruptions than data from local detectors. Two different types of technologies are applied for travel time calculation: infrastructure-based detection or Floating Car Data (FCD). As either of these approaches is in a different development and test phase and offers specific advantages, the pros and cons must be carefully considered before deciding on the implementation of either system. 10

11 Sitraffic Guide: Modules for parking guidance Parking data recording This module can be used to record occupancy data, opening hours and operational states of all connected parking facilities as the basis for situation-tailored parking guidance. Parking guidance sign control The system processes the parking data and generates the input for conventional remaining-space indication. In addition, the parking data can also be displayed together with other traffic data on freely programmable information panels and the parking guidance module can be operated as part of a higher-level traffic management system. Such a dynamic parking guidance system improves occupancy and profitability of the parking facilities, reduces the volume of parking-related traffic and the resulting environmental impact and, last but not least, makes the city more attractive by enhancing overall quality of life. Parking route management This module serves to define parking guidance routes. The individual routes can be activated in dependence on data managed by other parts of the system, for instance roadworks or event schedules, ensuring that the recommendation will guide the driver on the best route to the next available parking space. 11

12 Open interfaces and standards 1 Data exchange with different systems? A breeze thanks to open interfaces and standards 2 The system is capable of integrating traffic controllers of varying origins and generations 3 Communication via fiber-optic cable combines extremely high data throughput rates with maximum interference protection 12 Without open interfaces, smooth data exchange between a heterogeneous array of systems or the link-up of field devices from different manufacturers and different periods would be impossible. The use of interface standards ensures maximum ease of integration. The Sitraffic family of traffic center systems has full command of all these standards, ensuring effortless interoperability. OCPI (Open Content Provider Interface) Via this open interface, the Sitraffic traffic centers can exchange a wide range of data with the connected systems. The system can take over, for example, traffic bulletins, detector data, operational equipment status messages, data on roadworks, parking, the environment and the general situation; or send control commands to subsystems such as variable message signs or 3 rd -party traffic computers. Siemens ensures that the OCPI interface always remains fully upward and downward compatible across multiple software versions. This system stability guarantees investment security for our customers and enables long-term use of established interface converters. Sitraffic Canto (Communication in advanced new technology in outstations) Sitraffic Canto is a proprietary standard that Siemens is making available for licensing by other manufacturers in order to meet the customer s requirements for an open system. With Sitraffic Canto, Siemens ensures full operability of a heterogeneous field device landscape because this system provides an especially powerful method for center-to-field communication and can even be used to connect existing older controllers to modern traffic centers. It is compatible with all transmission technologies: fiber-optic cable, LAN, OTN, GPRS and Internet links. OCIT (Open Communication Interface for Traffic) OCIT has been defined by a committee manned by the different system providers and is a widely used standard in the area of traffic computer systems and traffic light installations. It exists in two versions: OCIT-O (outstations) for communication with the field units, and OCIT-C (center to center) for communication between centers. OCIT-O is a universally applicable interface that is not restricted to a specific communication medium. This interface serves to safely supply, control and monitor all device functions via remote access. OCIT-C are standardized interfaces between central components and systems. The OCIT-C standard encompasses the former OCIT-I process data und OCIT-I supply data interfaces and covers virtually all interface needs in traffic management. VDV (Verband Deutscher Verkehrsunternehmen) The VDV (Association of German Transport Companies) defines the contents of the telegrams used for local public transport prioritization. These telegrams contain the log-on and log-off messages of public transport vehicles and are radio-transmitted to the intersection controllers. The local traffic-actuated control routine processes this information and triggers the corresponding public transport priority scheme.

13 TLS (Technische Lieferbedingung für Streckenstationen) The technical supply conditions for outstations TLS describe a communica - tion standard for interurban highways. Via the TLS interface, the system receives traffic information, currently displayed VMS contents and general and environmental data that can be used as additional input for urban traffic control. TMC (Traffic Message Channel) TMC is a radio standard for the transmission of traffic bulletins to car radios. Via this interface, the traffic management system passes on traffic information directly to a broadcasting station. DATEX II DATEX II is a European standardization initiative for various traffic data and traffic information applications. The Siemens center supports communication via this standard, depending on the project

15 Strategic traffic management Synergies through integration In every city there are numerous traffic-related systems that are operated independently of each other and often by different operating companies or public bodies, for instance the traffic light systems run by the civil engineering office, the transport authorities operational control centers, the fire brigade s control center, public roadworks administration systems, event management centers or the dispatch offices of taxi companies. All these systems hold valuable data that could be put to good use in the scope of an overall strategic traffic management. A system that is to provide optimal traffic control and guidance needs to have access to the scheduled dates, times and locations for major cultural or sports events or important roadworks, for instance. Thanks to their open interfaces, our control center systems can draw from all these data pools, bringing even such extremely heterogeneous system landscapes together under one informational roof as essential input for the definition of efficient traffic management measures. The Sitraffic traffic center platform has been designed to communicate with a wide variety of systems that the individual modules draw upon. 15

16 Coordinated strategies against congestion Traffic flows can be influenced in various ways and by various means: Traffic light switching plans can prioritize certain direction lanes depending on the time of day or the specific situation; variable message signs can be used to adapt speed limits in dangerous situations, to open up additional lanes or recommend alterna - tive routes; traffic information systems support road users in choosing the best route and means of transport or plan their travel time. Sitraffic traffic management centers offer valuable tools for mastering the complex interaction between the traffic center, the variety of data sources and the actuators and for synchronizing and coordinating the different measures. The Strategy Management module can be used to specify the trigger values for defined packages of measures, factoring in all available relevant data. This coordinated method ensures that all available actuators in a city are activated in a targeted manner to defuse critical situations and master traffic overloads. Major traffic information platforms in Germany Siemens is extensively involved in the three most important traffic information platforms in Germany. Their immense scale in terms of spatial coverage and technical and administrative complexity turns these projects into prime examples of the enormous capabilities and potential of today s innovative technologies. Ruhrpilot Area covered: entire Ruhr region Inhabitants: 5.3 million Systems: national motorways, municipal systems, public transport Environment Internet: VMZ Berlin (Berlin traffic management center) Inhabitants: 3.4 million Systems: national motorways, municipal systems Internet: VIB Bayern (Bavarian traffic information agency) Inhabitants: 12.4 million Systems: national motorways, municipal systems, public transport Environment Internet:

17 In response to congestion, hazards, accidents, critical weather conditions or excessively high emission values, the system can initiate control and guidance measures and provide road users with timely information via radio broadcasts, Internet and/or roadside information panels. Our tools even support the necessary coordination between the various public bodies responsible for different transport networks, for instance municipal and motorway authorities, trade fair companies, port and airport authorities or stadium management, so that coordinated strategies can be implemented to steer the entire traffic and transport in the area. Intermodal traffic management: Optimal use of existing infrastructure For the optimal utilization of the capacity of the entire transport infrastructure, in particular in conurbations having to cope with high traffic volumes, the intermodal approach to managing the transport system is gaining in importance. Individual capacities, current traffic load of the network, disruptions in private and public transport and information on the transfer points between private and public transport are the backbone of intermodal traffic management. Intelligent control algorithms then enable the best possible use of the existing infrastructure for accommodating current mobility needs. Concrete measures are, for instance, the provision of constantly updated numbers on the occupancy of Park&Ride facilities or of public transport departure times or travel time comparisons via various media. Environmentally conscious traffic management: Keeping an eye on air quality Wind, weather and industrial emissions cannot be influenced by traffic control or guidance measures, of course. But efficient traffic management can signifi - cantly reduce the pollutant load caused by trucks and passenger cars (exhaust gases, abrasion, dust resuspension). Whenever the total pollutant load rises notably and approaches the legal limits, the responsible authorities need to take immediate, efficient measures, for instance rerouting of individual traffic flows or closure of certain zones for certain vehicle types. Effective air quality improvement is only possible if the current pollutant load and distribution is known. As the new Sitraffic traffic center platform incorporates the required environmental models, it can be used to record and monitor immission levels across the entire area. On this basis, remedial measures can be initiated right when and where they are required. 1 A modern traffic management system is able to integrate public transport timetables as well 2 Precise information encourages reasonable transport choices 3 A clear picture of the current traffic situation at a glance 4 Environmental sensors measure current pollutant levels at selected sites 5 Special models calculate pollutant dispersion in dependence on geographical conditions, building topologies, meteorological data, traffic volumes and background concentrations 6 All environmental and traffic data are aggregated at the Sitraffic traffic management center

18 User interface & operation Intuitive user interface, uniform handling For the operator, the ease of use of the Sitraffic traffic centers is an essential feature. The system must provide the user with clear and constantly updated information on the traffic situation and with the right tools for immediate intervention. For this reason we keep optimizing the graphical user interfaces of our traffic center systems. With the latest version of our traffic center platform, we have even gone one step further: The graphical user interface adapts to the processes and activities in the center. This application-oriented approach of reflecting the operational processes on the user interface makes system operation easier and more transparent. Improved grouping of system functions, the new screen management function, selective detachment of individual screens from the main frame, fast switching between different contexts, the possibility to define individual cockpit layouts all this adds up to a system that can be handled intuitively after only a short training period. Additional key advantages are the uniform user interface layout for all traffic applications and the shared data base for all tools. 18

20 Operation made ever easier 1 The optimized user interface groups all system functions logically in the navigation bar and the navigation tree 2 The new next/previous button allows fast switching between different contexts 3 The online help function provides detailed questionanswer explanations of the functions We keep improving the graphical user interfaces of our Sitraffic systems to make the user s tasks ever easier and more transparent. The latest version of our traffic center platform has been equipped with numerous new features for added system handling convenience. While we kept the basic layout, we perfected the grouping of the system functions in navigation areas and introduced the possibility of organizing individual screens in a cockpit layout according to the user s personal preferences. Open screens are embedded in a main frame and can be selected via the function tree. Faster navigation thanks to direct object access A click on an object automatically opens the corresponding drop-down menu offering specific operation and information choices. An object can be any trafficrelated entity, for instance an intersec - tion, a car park, a strategic measurement station, a variable message sign, a roadworks site or a route section. The screen layouts for detailed representation use the same structure for all objects and serve as user interface for both system operation and parameterization. The objects, including all details, can also be listed in tabular form, offering multi - ple filters and sorting functions for the preparation of comprehensive synopses. A uniform user interface layout saves time All traffic applications are operated via a uniform user interface. In addition, the Sitraffic Office software suite provides a number of valuable tools that support the intersection-related tasks of the traffic engineer, the control center operator and the service technician alike. As all tools access the same data base, data need to be entered only once, which saves time and eliminates potential error sources. GIS maps make orientation easy The network layout map is based on a digital Geographical Information Sys - tem (GIS). This means that each object is displayed at its exact geographical location. Dynamic objects are always represented by self-explanatory icons, with the icon s layout or color changing with the objects status or operational mode. For parking facilities, for instance, the system can display not only the operational status, but also bar graphs detailing the occupancy rates. The logical zoom function ensures that the network layout contains only the level of detail that is currently required and can be displayed clearly at the selected scale. Detail depth can be individually defined for each city and each user. Another clarity-enhancing feature is the tool tip function: When the mouse cursor pauses on an object, an information box pops up that displays the associated dynamic key data stored in the data base. 20

21 Convenient access to all information available in the system In our traffic centers, the users can easily retrieve and clearly display detailed information on all connected objects, access object status information and initiate measures. Where necessary, the user can adapt specific parameters and open diagrams or reports for detailed monitoring of individual systems. The intuitive handling facilitates the opera - tor s tasks and saves time. And the clear structure and detailed information enable very fast and targeted intervention, if required. The open OCPI or OCIT-C interface allows easy connection of subsystems supplied by other manufacturers. The interface can be used to exchange data, control subsystems and supply strategies

23 Services & support Support that really makes a difference Besides technological solutions, Siemens also offers a wide range of services for the traffic sector. For optimal alignment with the customers requirements, our service portfolio is just as modular and flexibly scalable as our traffic center technology. With our innovative financing, maintenance and planning services as well as attrac - tive operator models, we help take the strain off municipal budgets and ensure the reliable operation of all technical systems. Our Sitraffic traffic centers are, of course, perfectly covered by our extensive service portfolio. Some services have even been specifically developed for our traffic center platform. One such special service is the possibility for municipal authorities to use traffic center functions without having to build and operate a traffic center of their own. Application Service Providing is the name of this new Siemens service that allows local authorities to regain some of the financial freedom of movement that was lost to ever tighter budgets over the past years. 23

24 Affordable solutions aligned with individual requirements Application Service Providing (ASP): Renting functionality instead of buying a traffic center The demand for traffic centers that can be used without requiring extensive investments or binding resources on the part of the local authorities keeps rising. To meet this demand, we have developed our new ASP model. Under an ASP contract, customers can use selected functions of a Sitraffic Scala traffic computer system running in a Siemens-operated traffic center. The customers access the system from their PC via a secure Internet connection. Traffic controllers and communication hardware and connections within the field devices remain under the customers responsibility

25 Operator models: Using always the newest technology at calculable costs In many cases it makes economic sense to entrust the actual operation of certain traffic infrastructure elements to a competent partner. And thanks to specific resources and comprehensive knowhow, Siemens is just such a partner. We make the performance of traffic infrastructure and/or street lighting more transparent for a city s authorities. In the scope of such operator models, Siemens takes over the responsibility for both system operation and the continuous upgrade and modernization of devices and systems. This means that the customer can always rely on state-ofthe-art technology at fixed and calcu lable costs. Financial Services: Technology and financing facilities from a single source In times of limited budgets in particular, financing solutions are of increasing importance for Siemens customers. With our Performance Contracting or Energy Contracting models, we offer our customers virtually self-financing ways of realizing the necessary updates of their technical traffic infrastructure. Our range of classic financing solutions reaches from consulting and insurance right up to equity and debt financing schemes. As international provider of financing solutions in the business-to-business sector, Siemens finances infrastructure, equipment and operating resources. In Germany alone, Siemens Financial Services has more than 10,000 customers, including small and mid-sized companies as well as well-known multinational corporations, local, regional and national authorities and other public bodies. 1 Under an ASP contract, our customers benefit from the convenience of our optimized Sitraffic user interface 2 More and more major traffic centers are operated under the shared responsibility of municipal authorities and Siemens 3 Retrofitting traffic signal with LED technology reduces the related energy costs by 90 %. Energy Savings Contracts make such projects even more attractive 25

26 Optimized processes, perfectly matched 1 Regular system checks are the be-all-and-endall of guaranteeing equipment reliability; service agreements provide reassurance that no check is left out 2 Siemens training courses for engineers and planners are TÜVcertified; even old hands can still learn something there 3 Spare parts are dispatched from our logistics center in Neu-Isenburg to any location on earth within 24 hours Our service experts provide all necessary services for smooth and reliable operation to the required and requested extent. All services and performance options are perfectly matched to each other and based on an optimized internal organization that ensures that their provision runs like clockwork. That s how we achieve outstanding quality and speed in all areas from on-call service including online help desk, or fault elimination and emergency service right up to guaranteed system reliability. One of our proven tools is our efficient Remote Service technology. The customers benefit in many ways from these optimized service processes: Maximum availability of all technical traffic systems A single central contact point for all service requests related to all traffic technologies Access to our global service network providing an extensive expertise pool Consistent service excellence thanks to our closely meshed service network Reliable completion of time-critical services ensured by standardized processes and guaranteed service levels Predictable life-cycle costs Service contracts: Safety at a predefined level Customized service and maintenance contracts help ensure that each solution is serviced exactly to the extent desired by the customer. Local authorities with their own professional services team may only need to be reassured that in an emergency, all necessary spare parts will arrive within a defined time frame. Others need us to provide service technicians as well, while some customers will want to delegate the full responsibility for their traffic equipment, expecting guaranteed availability of the system 24 hours a day, 365 days a year. As every customer has a different idea what constitutes the ideal service level, we have developed contract modules that can be combined exactly as the customer needs and desires, and complemented by additional services as required. Training: TÜV-certified and based on practical experience Our hands-on training courses will help newcomers as well as experienced specialists expand and deepen their traffic engineering knowledge. Besides detailed know-how on our products and systems, we provide the participants with information on the latest developments in the traffic technology sector. The training program includes general knowledge classes and seminars on detection or controllers as well as units on traffic center systems or pay-and-display machines or a series of training courses on traffic planning and project development. By the way, our training units are the only ones in the market that have been certified by the German TÜV. 26

27 Consulting and engineering: Profit from the experience of the market leader Also during the planning, engineering and implementation phases, customers can profit from the wealth of experience and expertise that Siemens has accumulated in many decades of activity in the traffic engineering sector. Our consulting and engineering services cover all central topics of road traffic technology, for instance: Planning intersection control systems right up to overall traffic concepts for entire cities and conurbations Development and implementation of traffic management and parking space management plans Consulting on equipment optimization during ongoing operation Consulting on the energy savings potential of existing equipment realizable during ongoing operation A selection of major projects that we have implemented for our customers Location Berlin, Germany Braunschweig, Germany Dubai, United Arab Emirates Essen, Germany Prague, Czech Republic State of South Carolina, USA Project VMZ Berlin (Berlin traffic management center) BELLIS Falcon Ruhrpilot Urban Traffic Control PALGUIDE Goal Shorter travel times, enhanced safety, central control of traffic in Berlin Reduction of operation and maintenance costs (25% of existing equipment older than 25 years) Reduction of congestion levels and accident numbers on streets and freeways; integration of existing traffic control systems Integrated traffic management and information system for a conurbation with 4 million inhabitants for improved traffic flow in the area Reduction of congestion, link-up of all traffic signals to a central traffic control system Traffic monitoring, control and information system covering about 2,000 km of motorways in South Carolina Solution Siemens built a traffic management center collecting data from 8 traffic management systems, 22 traffic computers, 2,000 traf - fic light installations and about 100 video cameras as the basis for monitoring and controlling the entire traffic in Berlin In a joint venture with BS Energy, the power utility of Braunschweig, Siemens took over planning, operation and maintenance of the entire technical traffic infrastructure and all street lighting systems Siemens created a traffic management system, including a motorway management system with automate accident detection; all existing traffic control systems remain in operation Siemens was the main partner involved in the creation of a traffic center solution integrating 11 local traffic guidance systems, 7 parking guidance systems and 7 roadworks management systems and providing an area wide traffic information service (incl. public transport data) Siemens installed Integration of INRIX a modern traffic con - data and fog warning; trol and management automated incident system (Sitraffic Scala detection; integration and Sitraffic Concert) of 6 regional traffic and signed a long-term management centers; maintenance contract broadcasting of ensuring reliable system traffic information operation according to regions
