  3. Intelligent Transportation Systems • Everything in presentation is available, though not all in use • Obstacles: • Finances: Can’t afford to replace all old systems with new equipment or afford new systems • Inter Agency Trust and Cooperation: Turf issues, differing priorities, who has control • Public Acceptance: Politicians won’t support thing constituents are opposed to • Legal Challenges: Groups can challenge things in court, even if public supports

  14. Agenda Traffic Signal Operation and Automation Transportation Data Integration (TDI) for Traffic Corridors thru cell phones Traffic Enforcement thru technology Winter Maintenance Decision Support System Bridge Maintenance & Operational safety Construction efficiency – Machine Control

  15. TDI via Cell Phone data • Tracking of cell phones through urban corridors to track volume, speed, other pertinent data • Jacobs Engineering at forefront of use of this technology

  16. Jacobs Processing TDI – Cutting Edge Technology

  17. TDI – What does it do? • Operational Data • Speeds • Volumes • Congestion Points • Origin-Destination Information for all Travel • Can Separate by Mode • Buses/Trains/Transit • Cars/Trucks • Bicycles/Peds

  18. TDI – How does it do it? • Collects all “MOTION” Data • Detectors • GPS • License Plate Recognition • E-Tags • Cell Phones • Etc (Open System) • Data Fusion Process • Determines What Data Good/Bad • Uses Good Data • Creates 24/7 Operational Representation

  20. TDI – How can it be used? • Research • Automatic Traffic counters • Simulation of new roadway design/operation concepts (before) • Impacts of changes on entire roadway network • Automated measurements of test (after) • Impacts due to incidents can be catalogued • Impacts due to ITS devices (DMS, etc) can be measured • Environmental Impacts of Modal shifts • Benefit / cost analyses, true time savings estimates • Travellers • Personal Travel Predictions • By Mode • Intermodal • Future Travel • Best Mode/Best Route/Best Travel Time

  21.

  23. Agenda Traffic Signal Operation and Automation Transportation Data Integration (TDI) for Traffic Corridors thru cell phones Traffic Enforcement thru technology Winter Maintenance Decision Support System Bridge Maintenance & Operational safety Construction efficiency – Machine Control

  24. Traffic Enforcement Through Technology “Photo Cop” • Traffic Enforcement camera • Speed control • Red light running • Bus Lane enforcement • Toll roads • http://www.iihs.org/video.aspx/info/auto_enforcement

  25. Traffic Enforcement Through Technology – why needed? • 1,000 fatalities (nationally) per year due to “red light running” • 13,000 fatalities (nationally) per year related to excessive speed • Multiple injuries and accidents due to these violations • Limited manpower to address the problem (enforcement efforts are often short duration)

  26. Traffic Enforcement Through Technology – Benefits • Multiple research studies have shown: • Increased compliance w/ speed limits • 80% reduction in vehicles exceeding the posted speed by 10 mph where this has been used • Reduction in the number of fatalities and severity of accidents • Identifies and deters those that break the law • Enhances enforcement efforts • A fair, objective, and consistent application

  27. Traffic Enforcement Through Technology – Obstacles • Legal challenges to the use of monitoring equipment • Invasion of privacy? • Ticket issued to the vehicle owner, not the driver • Laser jamming devices on vehicles • Falsified license numbers on vehicles

  28. Traffic Enforcement Through Technology – MN Experience Minnesota Supreme Court Strikes Down Red Light Cameras The Minnesota Supreme Court delivers a unanimous decision striking down the legality of red light cameras.The Minnesota Supreme Court today delivered the highest-level court rebuke to photo enforcement to date with a unanimous decision against the Minneapolis red light camera program. The high court upheld last September's Court of Appeals decision that found the city's program had violated state law.The supreme court found that Minneapolis had disregarded a state law imposing uniformity of traffic laws across the state. The city's photo ticket program offered the accused fewer due process protections than available to motorists prosecuted for the same offense in the conventional way after having been pulled over by a policeman. The court argued that Minneapolis had, in effect, created a new type of crime: "owner liability for red-light violations where the owner neither required nor knowingly permitted the violation."Minneapolis Code of Ordinances sections 474.620 to 474.670, which make the owner of a motor vehicle guilty of a petty misdemeanor if the vehicle is photographed running a red light, are invalid because they are in conflict with the Minnesota Traffic Regulations, and specifically with Minn. Stat. Section 169.06, subd. 4(a) (2006), and Minn. Stat. Section 169.022 (2006). April 5, 2007

  34. Winter Maintenance Decision Support System • The Maintenance Decision Support System serves maintenance staff • decision support tool • real-time weather / roadway conditions • Combined with information on maintenance vehicle resources (i.e. salt, sand, etc…) • MDSS recommends appropriate roadway maintenance application treatments / rates • MDSS assimilates data on road surface conditions from Road Weather Information Stations (RWIS) • On-board vehicle sensors report pavement temperatures • also allows for field staff observations on road visibility to be factored into the MDSS recommendation for appropriate maintenance treatments. • With all sources of information taken into account, MDSS offers users various treatment options • such as “optimal” treatments – where travel safety is prioritized higher than treatment costs – • and “what-if” treatments – where the effects of several maintenance actions on overall resources can be understood by the system user before recommending certain actions.
