Expediting Vehicle Infrastructure Integration (EVII): where the rubber meets (and talks to) the road

  • Author(s): Varaiya, Pravin P
  • et al.

This research demonstrated two potential VII (vehicle-infrastructure integration) services, one in traffic data probes and the other with safety. A real private vehicle, operating on California roadways, “talked” to the roadside, with the roadside backhaul interfacing into an existing California Department of Transportation (Caltrans) database and archival application. Demonstration of a probe application showed great promise for supplementing Caltrans’ database with VII- or DSRC-based probe data. Similar promise was shown with a road condition monitoring system, which demonstrated the capability of detecting slippery and rough surfaces in real time.
