Transit Signal Priority

These are transit-only signals that allow ETS buses to leave an intersection approximately four seconds ahead of the rest of the traffic, even while all other traffic has a red light. These signals permit ETS operators to “jump” ahead of traffic congestion legally. A few seconds of priority at a congested intersection might help more than 40 people make their transit connections. When multiple intersection priority signals are used on the same corridor, they can play a pivotal role in efficiently moving thousands of people every day.

These are transit-only signals that stop traffic at a major cross street intersection so that ETS buses can safely cross the high traffic volume corridor or complete a turn. These signals are usually placed at intersections that do not warrant a full traffic signal and are often installed alongside a pedestrian crossing. Buses take more time to accelerate from a stop and are longer than passenger vehicles, so a natural break in traffic may be difficult to find without the help of these signals. Prioritizing ETS buses at key intersections is an effective method to help buses maintain a predictable schedule and operate safely.
