4 What we can do for you Meeting the requirements of today s increasingly challenging environment calls for the adoption of an innovative and dynamic approach. Exploiting the ITS infrastructure effectively, and in new ways, is key to delivering an efficient network and meeting obligations of the network management duty. As market leader in the supply of ITS, Siemens has extensive experience in the deployment and operation of UTMC and other ITS components providing real network benefits. Siemens can provide expertise at any level of involvement, from individual signal control schemes to regional strategic traffic management solutions. These solutions can be provided on an ongoing basis, with office-based staff providing a range of operational support services or by delivering a specific project brief. Our core expertise is focussed on five different sectors. Traffic Engineering Our design portfolio includes a wide range of projects of all sizes covering the implementation of new schemes as well as updating and the redesign of existing junctions. Working on such a variety of projects, aided by close liaison with our development and installation teams, keeps us exposed to the practical issues arising from signal design. Siemens offers a complete assessment and design service from traffic studies right through to implementation. Our dedicated regional teams use the latest software and recognised methods to provide bespoke and technically accurate designs. Our engineers have experience with all of the requirements for junction design including integration of pedestrian and cycle facilities, bus priority, and ITS. A comprehensive design file is supplied as part of our service and our expertise includes: Traffic modelling using LinSig, Transyt and microsimulation packages Traffic signal design (signalised crossings, intersections, roundabouts) using industry standard software including AutoTrack and AutoCAD with KeySignals Bus priority schemes Traffic management scheme design using KeyRoadworks including necessary designs for multi-phase construction TR2500 controller configuration forms Configuration of ITS including Siemens and Peek UTC systems and UTMC common databases 4

5 Operational Support As a leading supplier and integrator of ITS and equipment, Siemens has a unique insight into the challenges of managing and operating the active components, applications and networks which form the modern ITS infrastructure. This insight can be deployed to help our customers manage periodic and nonperiodic congestion, deliver reliable journey times, improve air quality, manage assets and enhance road safety. These solutions can be provided on an ongoing basis, with office-based staff providing a range of operational support services, or by delivering a specific project brief. This operational support can provide cost effective solutions by releasing valuable resources from unproductive maintenance tasks, allowing traffic management professionals to focus on exploiting the ITS infrastructure for the strategic management of the network. Our activities include: System support and configuration Remote or on-site system operation System health checks UTMC systems can benefit from a regular overhaul and reconfiguration to address transport network issues. Siemens team of experts can help get the most from systems through an in depth strategy and operational review. Strategy and Demand Management Traffic managers and operators today must manage information on the current status of the road network from a variety of disparate sources, analyse the data received and then implement a coordinated strategic response. All of this is undertaken under continual pressure on budgets and resources to demonstrate maximum efficiency of public expenditure. The range of traffic control and information systems available to manage the network offers many benefits but also demand effort in maintenance to ensure effective network management. Siemens has extensive experience of exploiting the ITS infrastructure to increase automation within UTMC systems. This can lead to greater efficiency and with reduced operator workload allowing the authority to improve the quality of service provided to the travelling public. Coupled with other tools such as microsimulation modelling linked to PC SCOOT, Siemens can offer the network manager a more realistic tool for network and event management. 5

6 Environmental and Economic Sustainability Ensuring that the service provided by the road network meets the needs of all stakeholders in the most environmental and cost effective way requires an active commitment to continuous improvement. This is essential to ensure that today s road network can meet the needs of tomorrow and is particularly true in a volatile economic climate were resources are already heavily utilised. Implementation As part of the complete turnkey solution offered by Siemens, we continue to support schemes through the installation and commissioning phases of the cycle to general maintenance and operation. Our activities include: Scheme delivery management Scheme designer attendance at factory and site acceptance testing Configuration of UTC and supporting ITS systems CLF, MOVA and SCOOT validation Bus priority including local and UTC/ SCOOT Ensuring that the design principles and strategies developed during the design stage work effectively in operation is an essential part of scheme implementation. Configuration of ITS combined with the final on-site validation ensures the junction is operating at its optimum to provide the effects required for maximising the performance of a complete network. Through a combination of site assessments, asset reviews and traffic modelling, Siemens can assess the feasibility of different improvement options that aim to reduce the environmental impact of schemes, improve efficiency and reduce ongoing operational and maintenance costs. This can include the review of intersections and corridors or an area wide review of UTMC communications or ITS technology energy reduction. This assessment would be used to identify opportunities for improvement such as; reducing operating costs and improving operational sustainability through the deployment of energy efficient solutions such as ELV, improving junction operation though the deployment of more efficient equipment or control methods such as MOVA and SCOOT, options for improving safety and operation through changes to the layout of signals and associated street furniture, optimising existing control strategies to reflect latest traffic patterns and driver behaviour, compliance with the latest legislation and guidelines. Siemens has a proven track record of working with clients to assess and modernise signal installations to improve safety, operational efficiency and sustainability. 76

7 Working in partnership with public and private sectors TfL Modernisation Siemens has been providing traffic engineering services to Transport for London (TfL) for many years. More recently, working through the TfL Consultancy Framework, our London based team has been assisting in the review and refurbishment of life expired traffic signal sites. Our project brief includes redesigning traffic signal sites to the latest TfL standards, capitalising on new technologies and recalculating signal timings to reflect current traffic patterns. Siemens role as Design Engineer and Project Engineer includes managing and coordinating the works on each site from design to implementation and commissioning. Arranging traffic management and ensuring that this aligns with other planned works is key to minimising network disruption. With in-depth involvement in the project management activities, we work closely with the many relevant stakeholders including TfL departments, local authority boroughs and external contractors such as BT, EDF and civils contractors. During the 2012/13 modernisation programme, Siemens was on track to deliver in excess of 45 schemes which was vital in ensuring that the year s modernisation targets were met. Reducing the queues in Barnsley The deployment of an innovative UTMC solution, combining SCOOT signal control and variable message signs in Barnsley has provided an automatic queue relocation system on strategic routes through the town. Providing real time information to drivers without any operator intervention, the solution uses standard components and existing on-street infrastructure to effectively manage congestion and minimise the impact of increasing traffic levels within the town. The overall goal of this project was to manage queuing on strategic routes throughout Barnsley by influencing signal timings in SCOOT and disseminating status updates via free text variable message signs automatically without human intervention. Whenever excessive queues occur, the UTMC system automatically adjusts SCOOT validation parameters in order to significantly reduce the queue on an approach or along a specific traffic corridor. As well as the automatic adjustments made to the SCOOT configuration when queuing is detected, the system also displays preset messages on free text variable message signs installed at strategic locations in Barnsley, providing timely and accurate information for road users. The solution is fully automated and operates 24/7 365 days a year with automatic consideration of both weekends and public holidays. The fully automated operation provides a cost effective solution as no additional operator resources are required to provide the enhanced management of the network. The project was commended by The Institute of Civil Engineers at the ICE Yorkshire and Humber Awards ceremony in March According to the judges, the project demonstrated excellent value for money in obtaining maximum benefit from the integration of existing assets and technologies. The scheme shows demonstrable improvements to junction safety and congestion around Barnsley, reducing the need for civil engineering at road intersections and for control personnel, as well as increasing road safety and the speed of traffic flows. The project was also runner-up in the Highway Magazine Excellence Awards in

8 Prestatyn Retail Park The introduction of a new shopping park in Prestatyn, North Wales, required significant highway improvement works in and around the town centre. This included the reversal of a one-way system and design of five signalised junctions, with the aim of improving traffic flow, pedestrian facilities and access to the bus station. Siemens completed traffic modelling of the proposed scheme in LinSig to test different operational scenarios before finalising detail traffic signal designs. The scheme was completed in 2012 with Siemens supplying and installing traffic signal equipment and developing and validating CLF plans on site. Signal upgrades across Blaenau Gwent In 2012, Blaenau Gwent County Borough Council identified the requirement to assess its traffic infrastructure as part of a larger programme of street lighting and street furniture refurbishment. Siemens completed asset surveys to determine equipment locations and condition at each installation throughout the county and produced a report detailing the findings of the survey with additional recommendations to improve safety and operational efficiency. Following the recommendations, Siemens worked closely with the council to develop a refurbishment programme that included ducting surveys, production of design drawings and technical documentation, installation of equipment and commissioning. At junctions that were identified as being close to, or over capacity, MOVA was installed and validated to peak period conditions following installation. Deeside Corridor Feasibility Study Flintshire County Council identified the need to undertake an assessment of the traffic signal controlled sites along the Deeside Corridor to investigate different solutions to improve journey time reliability and reduce delays. The corridor consisted of five junctions, three pedestrian crossings and a grade separated priority controlled roundabout interchange along a 2.7km single carriageway. Siemens was commissioned to undertake the assessment of the corridor, provide details of the findings and make suggestions for improvements with the associated traffic signal related costs. The study provided an assessment of each traffic signal controlled site commenting on the status of the traffic signal equipment, method of control, staging/method of control and suggestions for improvements. LinSig 3 was used to model each site to get a clear understanding of how each junction was performing and how alterations could lead to improvements. The assessment report was presented to Flintshire County Council to secure funding to implement future schemes. 8

9 Siemens Consultancy Services have been a vital partner in EnterpriseMouchel s supply chain since the start of the Managing Agent Contract s tenure in August 2008, through delivering turn-key projects to a high professional standard, under a very difficult economic climate. Geoff Williams, EnterpriseMouchel HA Area 3 Area 3 is the second largest Highways Agency area and covers 1,242km of carriageway across Surrey, Hampshire, Dorset, Wiltshire, Berkshire, Buckinghamshire and Oxfordshire. Since 2010, Siemens has worked closely with EnterpriseMouchel, the Managing Agent Contractor for Area 3, and completed a number of improvement projects over this time. With a firm focus on the environmental impact of the network and infrastructure, one of the first improvement projects focussed on the upgrade of traffic signal equipment to ELV, aiming to reduce energy consumption by approximately 70%. As part of this project, Siemens completed initial equipment surveys, produced a complete design package and handled the programme management during the installation and commissioning of equipment. Building on the increased energy efficiency, the next phase completed an upgrade to UTMC control with improved adaptive control and monitoring of sites across the area. The installation of UTMC OTUs provided the platform to establish MOVA and UTC control and allow adaptive control to manage the fluctuations in peak time traffic flow. The latest upgrade on the area network was the improvement of the Canford Bottom roundabout on the A31 in Dorset. As one of the busiest junctions along the A31, the junction experienced significant queuing and congestion at peak times. Siemens provided a turnkey design, supply and installation service completing the project in the summer of Port of Holyhead The Port of Holyhead is located on the Isle of Anglesey, North Wales and is linked to the local and wider trunk and motorway network by the A55. Located within the port, Holyhead train station has direct links to London and Cardiff. The port and the train station are served by two signalised junctions at either side of a bridge that crosses the rail line, and both junctions sit between the A55, Holyhead town centre and access to the port. The junctions suffered from poor signal head visibility, insufficient linking and did not cope well with sudden surges in traffic flow from the port. The port serves as an HGV route to Dublin and the insufficient linking meant that HGV traffic was frequently travelling through unsuitable residential areas instead of queuing to use the designated route along the A55. Siemens was commissioned to carry out an operational study of the junctions looking specifically at problems with visibility and the requirements of both HGV traffic to and from the port and local traffic between residential and retail areas. Different operational strategies were tested using LinSig and a detailed design package produced following consultation with UK Highways, Isle of Anglesey Council and the North Wales Trunk Road Agency. The design proposals included linked MOVA and queue detection as well as additional stages to clear large volumes of HGV traffic overnight to ensure that these vehicles used the preferred route away from the port. MOVA validation was completed following the installation of the new equipment and the additional operational strategies tested and enabled. 9

10 Improved car parking in Wrexham Wrexham, like many other towns, notices a lack of economic use of the Local Authority operated car parks. When car parks are full, motorists tend to wait, or continually drive around a car park until a space becomes available, unaware that there may be an available space at an adjacent car park. Giving motorists advanced notice of car park occupancy allows them to make an informed decision of where to park with minimal delays. Siemens was commissioned to evaluate traffic routes and car park occupation levels in Wrexham town centre with the aim of proposing a system that would enable drivers entering the town to make more informed decisions on car park choice. The system design initially involved discussions with the local authority to fully understand the requirements. The detailed design works included determining VMS locations, sign design and specification and car park signage. As well as the overarching operational strategy and system architecture including integration with the existing UTMC common database, Siemens provided detailed sign face designs and sign location plans including details of civils and utility connections. The proposed car park VMS and fixed plate signs are located to advise motorists of where the available spaces are as they enter the Wrexham inner ring road, and as they travel from one side of the town centre to the other. The VMS signs will be automatically updated with either a text or number description denoting the availability of spaces at a particular car park location based on an occupancy count. Improved road safety in County Kildare Working with our partners Traffic Solutions Limited, Siemens has provided traffic engineering works across the Republic of Ireland including the county councils of Donegal, Sligo, Offaly, Fingal, South Dublin and Kildare The Fortbarrington Road junction in Athy, County Kildare is a congested junction located on a main route in to the town. The two closely associated three arm junctions suffered from problems with queues on side road approaches and limited pedestrian crossing facilities. Following the decision to implement traffic signals at the junction to improve safety for pedestrian and vehicle users, Siemens completed a design package including details of vehicle swept paths and kerb realignment. MOVA configuration details were provided with the design and validation completed following commissioning of the traffic signals by Traffic Solutions Ltd. Brian Lee from Traffic Solutions Ltd said: as per previous projects, the design work was carried out in a very professional and timely manner. The client was extremely happy with the design provided and overall the project was considered a success. The MOVA controlled junction has greatly improved the efficiency and safety of the junction almost eliminating the queuing problems. 10

11 Blackpool to Fleetwood Tramway Trams have been operating in Blackpool since 1885 and form a key part of the local transport network as well as being a well known tourist attraction. The Blackpool to Fleetwood tramway has recently undergone a four year upgrade which included modernisation of existing traffic signal junctions as well as the introduction of new traffic signal pedestrian crossings and junctions, a total of 18 sites. The tramway and traffic signalling is controlled from a single controller with a direct link to the tram detection system achieving the strategic aim of providing faster journey times along the route using tramway priority. MOVA control was implemented at all sites to help minimize disruption to vehicle traffic following a tram priority call. In 2010, Siemens was commissioned by BAM Nuttall to deliver design packages for all of the traffic signal installations which included detailed AutoCAD scheme drawings of proposed traffic signal and tram signalling equipment, supporting technical documentation, controller configuration forms and factory acceptance testing. Following the installation of equipment, Siemens completed MOVA validation at all sites and validation of the tramway priority along the route was completed towards the end of Castlepoint Shopping Centre The management company of the Castlepoint shopping centre in Bournemouth regularly identified that that there were significant delays at the eastern exit from the centre. This often required the intervention of marshals to avoid grid lock within the parking area known as a Code Blue. The issue was raised with Bournemouth Borough Council who in turn invited Siemens to investigate the problem. The shopping centre is located along Castle Lane, a main arterial route which forms part of a SCOOT region. The scope of work was constrained by the limited budget for additional loop detection and the need to maintain the existing flows along the main route. To allow the SCOOT model to react to the exit demand from the shopping centre, loops were installed up-stream of the signal controlled entrance on to the roundabout at the eastern end of the development. To maintain the flow levels along Castle Lane and the offsets on the signalised roundabout, a SCOOT multi-node was optimised to maximise the effective green time for any single movement. Combined with additional detection and SCOOT validation, the operation of the exit was also observed and fine tuned in the peak afternoon and evening flow periods. The work was completed prior to the peak Christmas shopping period and led to no occurrences of a Code Blue. It s been the first year ever that this has happened, said general manager Peter Matthews. We had 20,800 cars here on the Friday before Christmas and 123,000 cars in the week before Christmas and no queues! 11

12 Andrew Knox from DRD Roads Service said: once again, can I express our gratitude for the improvements seen in traffic management in the west end of Enniskillen following the introduction of this project Enniskillen, County Fermanagh, Northern Ireland Enniskillen is well known as being an Island Town situated between Upper and Lower Lough Erne. The town s idyllic position has presented problems for traffic engineers over recent years and has become known for its bottle-neck effect. The western side of Enniskillen caters for traffic from the Republic of Ireland crossing two bridges to and from the town and over recent years increased traffic volumes has led to congestion at peak times. The two west end bridges help form a quadrangle for traffic to negotiate with two of the linking legs less than 50 metres in length. Two traffic signal controllers operate the system using four separate traffic streams. Historically, the system ran CLF for most of the working day to try and maintain progression, but the plans were considered out of date. In 2011, Siemens was appointed by the Department for Regional Development (DRD) Road Service to carry out an upgrade of the traffic signals to include MOVA. A design package was produced that included MOVA linking strategies to cope with the increase in traffic volume and the multiple opposing demands placed upon the network. The design proposals were approved and implemented in the summer of The sites showed immediate improvement in dealing with traffic queues and delays and motorists in the west end of Enniskillen are experiencing the benefits of shorter queues and reduced journey times. Capital-wide bus priority In 2007, Transport for London (TfL) embarked on an ambitious programme to rollout one of the world s largest integrated vehicle location systems. Supplied by Siemens, the ibus system uses satellite tracking and GPRS data transfer to track and pinpoint all 8,000 buses throughout the capital, providing bus operator and passenger information. An additional feature of the system is the ability to identify buses on approaches to junctions and provide priority at traffic signals. Using virtual detection points and equipment located at each traffic signal controller, bus priority was introduced at traffic signal sites across London. Siemens worked closely with TfL, adopting a rolling programme, including teams from both parties. Each junction was assessed for both suitability and cost benefit before site designs were produced. The completion of the installation, system configuration and site acceptance testing allowed TfL engineers to enable bus priority at each site. Bus priority using ibus has been successfully operational at 1,850 traffic signal sites since completion of the project in

13 Adaptive control The successful management of traffic in the 21st century places many demands upon the service provider. As the volume of traffic using the highways continues to grow at a greater rate than the capacity of the road network, the effect of traffic congestion is an ever-increasing problem in towns and cities around the world. Siemens experience in different methods of adaptive control and associated systems places us in the best position to recommend the most appropriate control strategy for a particular location. This could be MOVA, SCOOT or CLF or a combination of all triggered through UTMC strategies. Improved journey times in Middlesbrough A review of strategic routes in Middlesbrough by Siemens has produced journey time improvements of up to 31%. Improvements to the adaptive control on two separate SCOOT regions of the Acklam Road corridor scheme, including work to assess junctions and crossings, re-validate links and re-evaluate the underlying database structure. According to Alan Madgwick, Principle Engineer for Middlesbrough Council the improvements were made within the translation plans helping the region perform in a more dynamic way. Siemens experience of adaptive control and associated systems allows us to confidently recommend the most appropriate control strategy for a particular location. Our portfolio of SCOOT projects stretches across the UK and to our international customers. Our engineers also complete bespoke customer training either as part of on-site exercises or part of a more formal classroom training course. MOVA Similarly with MOVA, our engineers have a wide range of project experience from standalone junctions in urban centres to larger linked MOVA inter-urban projects. Siemens has completed MOVA projects across the trunk road and motorway network including junctions on the M27, M3, M4, M5 and M1. More recently we have completed linked MOVA validation at M1 J12 part of the J10 to J13 improvement project. Wireless detection in Edinburgh On the outskirts of Edinburgh, the junction of the Wisp and Newcraighall Road is located on a busy commuter route. Due to the proximity to the A1 motorway at Newcraighall and Fort Kinnaird, a large retail park, the junction has also become a point of congestion for shoppers during the weekend. To improve the capacity of the junction, Edinburgh City Council carried out a review of the layout and operation and completed a re-design of the junction. Siemens completed works to implement MOVA at the junction including producing the MOVA dataset. To reduce the requirement to install additional ducting, MOVA was implemented using wireless magnetometers. Following installation and commissioning, Siemens completed MOVA validation at the site. Due to the tidal flow, MOVA was configured with four time of day datasets to deal with the weekend and weekday scenarios. 13

14 The experience of the Consultancy team is invaluable... ensuring that we always implement the most appropriate solution Brian Daveney, Poole Borough Council Castle Quarter Improvements Siemens has provided traffic engineering support to Cardiff Council and their partners for many years, more recently working together with Cardiff Council and Birse Civils Ltd as part of the Castle Quarter and City Centre redevelopment. The project aims to improve transport links through the city centre and enhance pedestrian facilities between the castle and retail areas. This has involved highway and footway works along the route and the re-design and upgrade of nine traffic signal sites including junctions, pedestrian facilities and a bus gate. Siemens was involved in the project from the concept design of the new junctions through to final commissioning. As well as providing detailed traffic signal design packages, Siemens prepared interim traffic management layout designs and temporary controller configurations to ensure that the existing junctions remained under UTC control during the upgrade. Following the final commissioning of the sites, our systems engineers completed the configuration of the Cardiff UTC system and validation of SCOOT. This, together with strategy development using the Cardiff Comet system, ensured that the sites across the network region operated efficiently and adapted to specific traffic flow conditions. Extended customer support As a leading supplier of ITS and related equipment, Siemens has a unique insight into the challenges of managing and operating a local highway network. This insight has been used in recent years to provide support services to a number of our local authority customers including Poole Borough Council, Bristol City Council, Somerset County Council and Birmingham City Council. The services offered include many different aspects of network operation including: On-site UTC operation Asset surveys Completing audits of submitted schemes Factory and site acceptance testing Feasibility studies Following a large increase in the number of submitted traffic schemes coupled with several large developments in the area, Somerset County Council required some additional support for a three month period. Lee Ford, Senior Engineer form Somerset commented that Siemens have, at short notice, provided support for Somerset County Council during an extremely busy period. The support provided has been of a very high standard and has included providing technical advice on a number of safety audits along with invaluable assistance with our UTC system which has included SCOOT database amendments along with advice on possible future improvements. Very strict deadlines and critical timescales set have always been met and work has been completed to a high standard. For several years Siemens has supported Poole Borough Council with a combination of developer and council led projects, system support and general traffic engineering consultancy. Brian Davney from Poole Borough Council says that the experience of the Consultancy Services team at Siemens is invaluable during projects such as Twin Sails Bridge development. Our partnering approach ensures that we always implement the most appropriate solutions, it is good to know there are local experts we can rely on for advice 14

15 Kevin Monaghan, Divisional Roads Manager for Southern Division welcomed the changes saying: The implementation of the linked MOVA control system by Siemens was carried out efficiently and has had a very beneficial effect on traffic flows in the area. UTC review in Norfolk During 2011, Siemens completed a comprehensive review of the daily timetables and CASTs (Commands Actioned and Stored Together) used in Norfolk County Council s UTC system. The purpose of the review was primarily to simplify and streamline all of the currently used daily timetables and discover if the existing six day timetables could be reduced. The review would also ascertain what would be required to optimise each SCOOT region to eliminate any inconsistencies and allow each region to operate automatically without the need for a timetable. Based on the initial review, Norfolk County Council decided to rollout the automatic switching of SCOOT based on real time traffic flow. This resulted in the daily fixed timetabled events being replaced with dynamic events generated from the times that specific SCOOT detectors exceeded flow thresholds. By 2013, more than half of the 54 SCOOT regions had been converted to automatic operation. Detailed analysis has shown that SCOOT operation was activated at times of high traffic volumes outside of the usual peak periods providing greater progression through the regions. Key junction upgrade in Banbridge Siemens completed a major upgrade to three key signalised junctions in the town centre of Banbridge, Northern Ireland on behalf of the Department for Regional Development (DRD) Craigavon. Before the upgrade took place, S-Paramics microsimulation modeling was carried out to determine the feasibility of linking the junctions using MOVA. All three junctions were heavily congested in both peaks and lie on a strategic commuter route for the area. The locality of a large school and its associated morning drop off were major factors contributing to queues regularly extending over half a mile on the worst affected approach. A small gyratory system operating within the middle junction restricted road width over a bridge and the presence of regularly used bus stops within the network of junctions all contributed to the difficulty of improving traffic flow through the area. The S-Paramics model tested several scenarios and included linking to MOVA using TRL PC MOVA software. The model showed that the implementation of MOVA would provide an immediately reactive system giving a more effective response to changing traffic profiles in the peak and achieving better management of the long queues currently building up under existing CLF plans. The implementation of the linked MOVA control was carried out by Siemens leading to a marked improvement in traffic flows in Banbridge town centre
