The Federal Communications Commission recently answered a question that impacts US-based traffic, first response, and transit agencies: Which of the proposed communications methods will be adopted to serve vehicle-to-vehicle and vehicle-to-infrastructure communications, DSRC or C-V2X?
Fairfax County, Virginia is currently testing the first driverless public transportation vehicles in the Washington DC region. The 100-percent electric vehicles are also equipped with EMTRAC Transit Signal Priority (TSP) to safely decrease wait times at intersections.
When city managers explore implementing, or improving, signal priority for transit and first-response vehicles, rarely is it for low-congestion corridors. In most cases, the streets equipped with Transit Signal Priority (TSP) and Emergency Vehicle Preemption (EVP) functionality are also the streets with the greatest travel demand.
