1 Dynamic modeling for traffic organisation Dr. Gabriele Domschitz, Managing Director Wiener Stadtwerke 1 Titel Name, Abteilung

2 Modal split in Vienna 2

3 3 Individual traffic by car

4 Traffic in Vienna Gains in public transport, but cars are still part of the city Good cooperation of the various modes of transport has priority Vienna hopes to make car journeys environmentally friendly too E-taxis E-mobility for commercial vehicles 4

5 Traffic controll on Vienna s urban highways Asfinag Improved traffic flow, more road safety, less congestion and environmental pollution 5 ASFINAG, a state-owned company, plans, finances, builds, maintains and operates Austrian motorways Condition of traffic and road surfaces, weather, noise and pollutants are measured. Speed limits, overtaking restrictions, warnings and information are derived from this in a flexible and relevant manner. Some operations will be done automatically; many are carried out by ASFINAG operators.

6 Traffic controll on Vienna s urban highways Asfinag Drivers receive information on alternative routes or redirections. Early information in case of congestion and roadblocks. Fewer vehicles are affected by congestion. Central management of roadblocks. 850 webcams provide information on the current traffic 6

7 Data for traffic management Asfinag The ways of gathering, storing and processing data for traffic management systems on motorways in Austria sources of data and what kind of data is generated? system architecture 7

8 Sources of data Automatic operation cycle of traffic control system Asfinag 8

9 Sources of data Asfinag road side infrastructure vehicle count, speed + classes wind (speed, direction) cameras air + road surface Temperature water film thickness / road wetness concentration of remaining salt luminosity + visibility (fog) humidity + atm. pressure rainfall intensity pollutant immissions additional systems weather data + forecasting construction site management system 9

10 Various kinds of data are necessary for traffic control system Asfinag traffic data volume (8 different categories) current speed density distances and time between vehicles occupancy environmental data air: air temperature, humidity, wind speed and direction, immission, ground: ground temperature, water film, percentage of road salt, weather: visibility range, rainfall road sign data current and historical state of all road signs 10

11 11 Modelling public transport

12 Modelling public transport in Vienna Structural measures Traffic light controls 12 Passenger information systems

13 Structural measures in favour of the Public transport Bus lane Bus bays Bus trap (stop without passing) Passable bus boarder Strategic arrangements of stops in line with traffic light positions 13

14 Traffic light controls Public transport may influence traffic light controls Automatic announcements of bus and trams at the next traffic light; Traffic light for public transport is set to green to avoid unnecessary stoppages outside stops Buses take priority when leaving stops and may drive in front of private vehicles Enables punctuality and regularity of public transport 14

15 Traffic control system Underground control centre Tram and bus Control centre for surface transport Computer-controlled traffic control system Vehicles can be localised so that it is possible to react immediately to timetable changes (shorter route, reduce speed, etc.) Enables diversions and shorter routes Time table scheduling and roster scheduling 15

16 Passenger information By-product: Passenger information system Passengers receive real-time data via information pillars Qando: Digital customer information for Vienna Routing and payment Web-based and as app 16

17 Costumer information for the future Wien Mobil Multimodal route planning Notification of modes of transport nearby Reservation (car sharing or taxi) Payment Saving frequent destinations as favourites 17
