Santa Clara VTA Transit Signal Priority Solution
The transit signal priority solution project helps the Santa Clara Valley Transportation Authority (VTA) improve bus operations and reduce transit delays. The County of Santa Clara selected Econolite to design and deploy a system that allows buses to request priority at key signalized intersections.
Because timely transit improves rider satisfaction and operational efficiency, the County prioritized this solution as part of its transit and mobility program. As a result, buses travel through corridors more smoothly, and riders experience improved reliability.

| Solution | Transit signal priority system |
| Technology | Priority logic integrated with signal controllers |
| Benefits | Reduced bus delays and improved schedule adherence |
Key Project Outcomes
- Reduced delay at intersections for priority transit buses
- Improved schedule adherence for bus routes
- Enhanced connectivity between transit and traffic operations
- Greater visibility into signal performance data
“Implementing transit signal priority allows the VTA to reduce bus travel time and improve operational efficiency while minimizing impacts on other traffic movements.”
Transit Signal Priority Solution Overview
Transit signal priority (TSP) gives buses the ability to communicate with traffic signals so that timing can be adjusted in real time. This may include extending a green phase, shortening a red phase, or providing early green time when a transit vehicle approaches an intersection.
TSP helps buses maintain schedule reliability by reducing the amount of time they spend stopped at red lights. This is especially valuable on high‑frequency routes where minor delays can accumulate quickly.
Deployment and Integration
Econolite worked with VTA staff and local agencies to configure and deploy the transit priority solution. Key elements of the deployment included:
- Integrating priority logic into traffic signal controllers
- Working with detection systems for priority requests
- Testing and calibrating signal responses for corridor performance
- Coordinating with transit operations teams for timing strategies
- Validating performance under real traffic conditions
These steps ensured that buses could reliably request priority and receive appropriate signal timing adjustments without adversely affecting overall traffic operations.
Technology Used in This Project
- Centracs® ATMS for monitoring and control
- Centracs® Signal Performance Measures for analytics
- Traffic Signal Controllers supporting priority logic
- Advanced Detection Systems for vehicle presence
- Intelligent Traffic Sensors for real‑time data
These technologies help ensure that priority requests are supported by accurate detection and timely controller responses.
Operational Benefits
The transit signal priority solution provides measurable benefits for VTA and riders:
- Reduced bus delays at intersections
- Improved schedule adherence on priority routes
- Enhanced rider experience and transit reliability
- Better coordination between transit vehicles and traffic signals
- A flexible platform for future transit enhancements
Because this solution integrates with existing controllers and management platforms, it provides a scalable foundation for future mobility improvements.
