Palm Beach County Transit Signal Priority

Project Description: TSP. Scope developed, to be advertised within the next 6 months; initially two routes. Palm Tran 42 and Palm Tran 63. The TSP system will function through a server–based, back–end system betwen the transit and traffic management centers.

Project Status: On-going

Project Stakeholders:

• Palm Beach County Engineering Department
• Palm Tran

Project Service Packages:

• PT09: Transit Signal Priority (Palm Tran)

Project Functional Requirements (Element - Functional Object):

• Palm Beach County Field Equipment - Roadway Signal Control
• 1: The field element shall control traffic signals under center control.
• 10: The field element shall receive request for transit vehicle signal priority.
• 4: The field element shall report the current signal control information to the center.
• 6: The field element shall return traffic signal controller operational status to the center.
• 7: The field element shall return traffic signal controller fault data to the center.
• 8: The field element shall report current transit priority status to the center.


• Palm Beach County TMC - TMC Multi-Modal Coordination
• 1: The center shall respond to requests from transit management centers for signal priority at one or more intersections along a particular transit route.


• Palm Beach County TMC - TMC Signal Control
• 1: The center shall remotely control traffic signal controllers.
• 4: The center shall collect traffic signal controller fault data from the field.


• Palm Tran Transit Systems - Transit Center Priority Management
• 1: The center shall analyze transit vehicle schedule performance to determine the need for priority along certain routes or at certain intersections.
• 2: The center shall send requests for priority along routes or at intersections to traffic management.


• Palm Tran Vehicles - Transit Vehicle Signal Priority
• 1: The transit vehicle shall determine the schedule deviation and estimated times of arrival (ETA) at transit stops.
