Train-Triggered Warning Signals Result in Large Animals Fleeing Approaching Trains 6.5 seconds (62 percent) Earlier, and Small Animals Fleeing 3.3 Seconds (29 percent) Earlier.

Methodology Two pairs of sites were selected where animal observations were expected to occur most frequently. In each pair, one site was equipped with the warning devices (the treatment condition)…

A simulation study modeled the impacts of a weather-responsive traffic signal timing system in Waterloo, Canada and estimated the system can reduce total intersection delay up to 20 percent.

FINDINGS The evaluation results show that the efficiency benefits of implementing weather-specific plans on a coordinated corridor are significant, especially for coordinated directions. The…

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:…
