Traffic Signal Priority

Enabling dynamic priority and pre-emption for Connected Mobility

As transportation agencies strive to improve traffic flow, road safety and multimodal mobility, Traffic Signal Priority has become an essential connected mobility service. Delivering priority and pre-emption to emergency vehicles, public transport, freight and cyclists requires secure, interoperable and real-time communication between road infrastructure, connected vehicles and mobility service providers.

This whitepaper explains how Networked V2X enables dynamic Traffic Signal Priority through secure, standardized and interoperable real-time data exchange. It shows how transportation agencies can scale priority services by combining centralized data exchange, policy management and intelligent request validation while maintaining interoperability across multiple service providers and infrastructure systems.

In this whitepaper, the term Traffic Signal Priority covers both priority and emergency vehicle pre-emption, reflecting terminology commonly used across Europe and North America.

The whitepaper explores:

• Dynamic Traffic Signal Priority and emergency vehicle pre-emption
• Secure real-time communication between traffic signal controllers, connected vehicles and mobility service providers
• Managing road authority priority policies across multiple road user groups
• Validating priority requests while maintaining operational performance
• Standardized and interoperable priority services
• Building scalable and future-ready connected mobility ecosystems

By enabling transportation agencies, mobility service providers and infrastructure operators to securely exchange real-time mobility data, dynamic Traffic Signal Priority becomes more flexible, scalable and effective while reducing the risk of vendor lock-in.
