  1. Traffic Models in the Traffic ManagementWorkshop Domain 3, May 7 – 8, 2001VIKINGAlf Peterson, Vägverket Region Stockholm - SNRA

  2. Traffic Management Plans in Stockholm - an implementation • Background • Operation • Exemples of Models Wiking Workshop, May 7-8th, Hannover

  3. Traffic Operation • Co-ordination between actors • Directive from Government • The Partners strive for an optimised use of the whole transportsystem, which should be seamless • Multi-modal oriented • ”smart” tours • get information before trip • get information en-tour • Expedients for this • Public information - Road Operators, Radio etc • Customised information - Service Providers • Information along the road - Road and Public Transport Operators Wiking Workshop, May 7-8th, Hannover

  4. Example Essingeleden E4 Wiking Workshop, May 7-8th, Hannover

  5. E4 Essingeleden – mobility in terms of speed and fuel consumption Bredäng Start tid: 07:25:01 Stora Essingen Fredhäll Tomteboda Solnabron Eugenia Västberga Nyboda 100 90 80 70 60 50 40 30 20 10 0 Hastighet km/h Genomsnittshastighet på vägsträckan Genomsnittshastighet: 6.9 km/h Bränsleförbrukning: 2.56 lit/10 kml Genomsnittshastighet : 19.4 km/h Bränsleförbrukning: 1. 29 lit/10 km Genomsnittshastighet : 69.5 m/h Bränsleförbrukning : 0.64 lit/10 km Wiking Workshop, May 7-8th, Hannover

  6. Vägtrafikcentralen S T O C K H O L M Co-operation City of Stockholm • Joint TMC • ”Joint” roadnet - seamless • ”Road assistance” • Exchange of • Traffic data • Disruptions • Roadworks etc. • Web www.trafiken.nu Wiking Workshop, May 7-8th, Hannover

  7. Joint user interface Decision support system A stored and complete bedding/support fast and correct measures, TMP improved mobility and minimised damage and risks Traffic Managemet SystemCTS , Central Technical System IN DATA Automatic alarms from all connecting systems , Telephone, Traffic data, Video, Weatherinfo, Co-operating partners mm SCENARIOS Traffic Management Plans THE OPERATION OF MEASURES Mail, Fax,Telephone,TMP´s via connected systems, Vägassistans mm Wiking Workshop, May 7-8th, Hannover

  8. Confirmed report Confirmr the report Register the report Registered report Delete the report TMP in operation Finalise the report Without a TMP Deleted report TMP restored Traffic Management Plans Generic report Create a new report Make a choice and operate a TMP Restore plan Finalise the report without confirmation Finalised report Finalise the report after restoration of TMP Wiking Workshop, May 7-8th, Hannover

  9. Operators can intervene in different systems Wiking Workshop, May 7-8th, Hannover

  10. Screen view Wiking Workshop, May 7-8th, Hannover

  11. Development of roadside systems • GIS • Maps • Joint roadnet database, NVDB • Technical system • Intelligent traffic signals • Motorway Control System (MCS) • Real-times based traffic models • Variable Message Sign • Organisation • adaption and development • Evaluations Wiking Workshop, May 7-8th, Hannover

  12. Incident ManagementStockholm • Road- assistance • Dispatched from VTC • Radius ca 10 km, main road networkt • Operating time 0630 – 1930 working day • Two trucks • Tow-away vehicle • Policé Wiking Workshop, May 7-8th, Hannover

  13. The Operaters need processed information Exemple: • Journeytimes between optional locations (O-D) • normal journey times • current journey times • Journey time predictions – 15 resp. 30 minutes • scenarios - descriptive • Three different methods • Contram ITS, an off line modell (mezzo) – normal journey times, scenarios • Matrix, an realtime model, current jouney times related to O-D, control functions • Probes, position data from existing users, current journtey times Wiking Workshop, May 7-8th, Hannover

  14. Incident location Incident delay estimates (veh.h): Modelled 990 Observed 1500 Increased congestion after 30min Off-line tactical use Rear-end collision Essingeleden during am peak hour (speed difference in km/h compared with normal situation) Contram Scenario Wiking Workshop, May 7-8th, Hannover

  15. Off-line tactical use Preliminary location of VMS in Stockholm 1st step Emme/2 2nd step Contram Wiking Workshop, May 7-8th, Hannover

  16. Off-line tactical use Incidents and VMS modelled VMS Contram Scenario VMS VMS VMS Incident location VMS Wiking Workshop, May 7-8th, Hannover

  17. Off-line tactical use Accident at Roslagsvägen during am peak (speed difference in km/h compared with normal situation) Left: No VMS and re-routing Right: VMS noticed by 50% of drivers VMS E4 at Järva Krog more congested Situation after 40min, incident just cleared Wiking Workshop, May 7-8th, Hannover

  18. 7.15-7.35 Incident and VMS Incident and no VMS 7.35-7.55 7.55-8.15 Total network improvment 714 veh.h. 8.15- Wiking Workshop, May 7-8th, Hannover

  19. Test area To be extended • Parameters • link/lane • Length • nod/junction • capacity • v/d functions • O-D pattern • centroides • Detectors and indata • Probes and indata • Calibration • Flows • Validation • journey times Wiking Workshop, May 7-8th, Hannover

  20. MATRIX a realtime traffic automation- system, a generic information and “control” platform “SLOW” ASSIGNMENT O/D ESTIMATION CYCLE • Stockholm: • Information från: • MCS • Image processing • Traffic Signals • Traditional detectors • Intelligent traffic signals • Probes “FAST” CYCLE CONTROL Via traffic- systems MONITORING Of road network Wiking Workshop, May 7-8th, Hannover
