Wireless-enabled Safety Services in California: VII California, Intersection Safety and Other Emerging Innovations 2008-21-0010

The VII California testbed and proof of concept development is an emerging collaborative testbed with partners drawn from public, private and academic sectors. The goals are multiple and evolving: first, to inform Statewide and regional stakeholders and research participants on the value of Vehicle-Infrastructure Integration (VII) mobility and safety applications in the San Francisco Bay Area context, then progressively, to serve as a VII Development Test Environment (DTE) for unique elements of the Proof of Concept (POC) experiments for the viability assessment and finally, to serve as a launching point for applications development and testing for selected VII services.

A consistent goal, however, is use of the testbed to develop and eventually enact safety services using Dedicated Short Range Communication (DSRC). It was at this testbed that intersection signal phase and timing interfaces for multiple controller types were developed and intersection geometry description messages were first tested; moreover, it is at this testbed that DSRC-enabled curve overspeed warning concept was first tested.

This paper describes the VII California testbed, the work done as a DTE in the VII POC, then it focuses on the DSRC-enabled safety applications being developed and tested at VII California with particular focus to one of the most important, intersection safety applications. The paper concludes with a description of future research and a development model for a potential limited-scale deployment using VII California as a launching point.
