How does Transit Signal Priority (TSP) impact the overall traffic system?

Transit Signal Priority (TSP) plays a critical role in enhancing the efficiency of public transit systems. By prioritizing buses and other transit vehicles at traffic signals, TSP reduces delays faced by these vehicles, which leads to faster travel times. This improvement in travel efficiency is crucial because it encourages the use of public transit, making it a more attractive option compared to private car travel.

When TSP is implemented, specific transit vehicles receive green lights when they approach intersections, or existing signals may be adjusted to minimize stopping time. This strategic move not only benefits those who utilize public transit but can also lead to better overall traffic flow in urban settings, as efficient public transport can decrease the number of vehicles on the road. Thus, the primary effect of TSP is its positive influence on the travel efficiency of public transit, promoting a more reliable and effective transit system, which is beneficial for the entire traffic network.
