Spain – Smarter traffic light priority in Vitoria-Gasteiz
A key step toward smarter, real-time public transport priority – enhancing bus flowand commuter experience in Vitoria-Gasteiz.
Scope:
Pilot project for bus transit signal priority using connected vehicle technology
Kapsch Solutions:
Transit Signal Priority, EcoTrafiX™ Suite, RIS-9160 RSU, CBX-9160 OBU, CMCC
Key Outcome:
Reduced delays for buses, improved commuter experience, scalable model for other cities
Next Generation funds within the Ciudades Conectadas project
A need to optimize traffic flow and support sustainable mobility
The city of Vitoria-Gasteiz sought to improve the punctuality of its BRT system by reducing delays through a priority solution at intersections. This meant integrating new technology into the existing urban environment without disrupting daily traffic operations, while ensuring a scalable approach to enhance overall service efficiency.
Connected vehicle technology forreal-time bus prioritization
In 2024, Kapsch TrafficCom Spain was awarded a pilot by TUVISA to implement Transit Signal Priority (TSP) through connected vehicle technology. The solution integrates the latest-generation Kapsch 5.9GHz roadside units (RIS-9160) and onboard V2X communication units (CBX-9160) with existing traffic management systems, coordinated by the EcoTrafiX™ Suite and Connected Mobility Control Center (CMCC). The system uses real-time GTFS data on bus schedules, position, speed, and delays to dynamically adjust traffic signals. This grants buses on Line 5 priority at a key intersection, reducing wait times and improving service reliability.
Key elements of the solution include:
- RIS-9160 roadside and CBX-9160 onboard units
- GTFS connector for processing schedules and delays
- Integration with EcoTrafiX™ platform and controllers for automated green phases
- Continuous whitelist updates via the CMCC
