Transit signal priority (TSP) is not a new concept. Traffic engineers were providing transit priority in the 1960s. Even before the advent of detection for transit, traffic signal timing was adjusted in some cities to favor transit’s operating characteristics. This webinar discusses different types of transit, passive transit priority, elements of traffic signal priority systems, emerging new design standards, how to determine where and when to apply the new standards, and implementing these treatments. Examples of where these treatments have been implemented are provided.
Purpose and Background
Traffic engineering for transit is an effective strategy for reducing costs for transit agencies. Physical improvements come in a variety of forms and have been deployed with a wide variety of success throughout the U.S. and the rest of the world. Advances in technology have provided engineers with opportunities to facilitate the movement of in-service transit vehicles, either buses, streetcars or light rail vehicles through signalized intersections. TSP offers a cost effective approach to pursuing a number of valuable objectives including: reduced transit travel times, improved schedule adherence, improved transit efficiency, and increased road network efficiency as measured by person mobility.
New advances in Global Positioning Systems, detection and communication, and control strategies have overcome many problems with early systems and increased interest in implementing TSP for Bus Rapid Transit (BRT) and other transit operations. The increased capabilities of these advanced systems have led to a dramatic increase in operational and planned TSP deployments across the U.S. TSP has come to be considered a key component of the Federal Transit Administration’s Bus Rapid Transit (BRT) initiative to use ITS and other innovations (e.g. vehicle design, right of way improvements) to attain the features of rail rapid transit systems (e.g. minimum delay, reliability, identity).

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion
To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.
How do I convert CEUs to PDHs?
1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
