NextGen Traffic Operations Data Service

Status: Planned

Description: The Next Generation Data as a Service provides continuous, overlapping coverage of road conditions across lanes and shoulders, feeding into a distributed edge compute system that processes sensor data in real time. It will deliver data directly to VDoT's traffic operations centre through a real–time dashboard, and support the delivery of lane–level alerts to connected vehicles, commercial fleet operators, and navigation partners on the corridor. Hazards will be detected earlier and response times decreased.

Stakeholder: NextGen DaaS Provider
