Microsimulation Study Shows That Traffic Signal Priority Reduced Travel Time by 3.4 Percent With 5 Percent Heavy Commercial Vehicle Platooning, Although Higher Penetration Rates May Cause Delays.

METHODOLOGY Five scenarios were developed to investigate the operational impact of Level 4 HCV platooning on urban arterials with existing traffic controls and with the addition of TSP for HCV…

Toronto, Canada

The City of Toronto finds that use of UAVs can be valuable for special event traffic management, but that use of UAVs to manage unplanned traffic incidents is not currently feasible given their unpredictable nature.

Content references source material no longer available at its original location.

The City of Toronto's Transportation Operations Centre (TOC) teamed with the University of Toronto to explore the potential to use UAVs for traffic management. The project objectives were to:…

Toronto, Canada

Vehicle-to-infrastructure emergency vehicle signal preemption application found to reduce emergency vehicle response time by 43 to 51 percent depending on traffic density.

Results The simulation found significant EVRT savings. In a high-density area the method reduced EVRT by 50.94 percent, in a medium-density area the method reduced EVRT by 44.41 percent, and in the…

Taxonomy (ARC-IT) Transit Traveler Information (PT08)

Geolocation links

San Francisco, California, United States | Toronto, Ontario, Canada

In networks with work zones, connected vehicle market penetration rates under 40 percent may contribute to a safer traffic network, while market penetrations above 40 percent may decrease network safety.

FINDINGSConnected vehicle applications can reroute drivers around work zones but at the expense of longer average trip distances which can decrease safety. Combining the most conservative driver…
