California Partners for Advanced Transportation Technology

In this project we have accomplished three goals. First, we have merged two existing, complementary databases in an effort to produce a single database that lists all the railroad crossings, and their known properties, in the San Joaquin Rail Corridor (SJRC). Second, we have demonstrated the practicality of using video data gathered from an existing Locomotive Video Data Acquistion System (LVDAS) to search for crossing violations in order to populate a database of crossing violations, which we term “near-misses”. By this means, crossings that are particularly susceptible to violations, considered a precursor to collisions, can be identified. Third, we have demonstrated a new in-pavement crossing signal based upon LED technology, that can serve to increase safety at crossings.
