Arterial Travel Time System


Stop Modelling What You Can Measure


City transportation planners can now utilize arterial travel time, along with speed, occupancy, and volume measures to reduce traffic congestion.

This infrastructure based solution will decrease fuel consumption, vehicle pollution, and the amount of time vehicles are on the road in metropolitan areas.

Sensys Arterial Travel Time is the first turn-key, integrated and maintainable solution that meets the stringent accuracy requirements for urban traffic data systems.

Almost all of the data currently being utilized for traveler information systems and 511 servers are based on average or estimated travel times. The Sensys system does not smooth out traffic peaks and troughs, it delivers the entire distribution of travel times.


Close the System Performance Measurement Loop


The Sensys Arterial Travel Time solution is the first solution to deliver dependable arterial travel time and volume data while not presenting any privacy concerns. Arrays of wireless sensors at periodic intervals along the arterial capture anonymous magnetic signatures from vehicles. A patented algorithm re-identifies individual vehicles, producing accurate travel times and traffic volume data.

With the Sensys Arterial Travel Time solution, cities, counties and state agencies are able, for the first time, to provide accurate traveler information on their arterials, and obtain the data required to improve their traffic management systems and support their planning.






Why Pay For Probe Data?

  • Probe data has a low penetration rate
  • Arterial data isn't uniform or predictable
  • Traffic patterns on arterials are unpredictable -- they require real time (24/7) accurate data






Applications:


Traffic Engineering Analysis
  • Signal timing optimization
  • Origin-Destination studies
  • Traffic demand models
  • Eliminate the need for probe vehicle runs
  • Baseline data for traffic mitigation programs
  • Measuring and reporting historical travel times for analysis
  • Integrates with leading ATMS software
Traveler Information
  • Dynamic Message Signs
    Collecting and using travel time from an XML datafeed
  • 511 Systems
    Measuring and reporting current travel times via a color-coded map


Features:


Performance Measures
  • Complete distribution of travel times
  • Median travel time (sec)
  • 80th & 90th percentile
  • Number of vehicles per segment
  • Level of service (as defined by TRB Highway Capacity Manual)
