San Joaquin Rail Corridor Crossing Survey


Bradley Mizuno

Task Description

Research to identify what factors cause or predispose toward railroad grade crossing collisions. Three key tasks with associated specific deliverables: 1. Merge Crossing Databases 2. Use the recently installed Locomotive Video Data Acquisition System (LVDAS) installed by PATH at Caltrans' request in their locomotive 2008, to begin the process of assigning near miss events to the crossing at which they occur. 3. Conduct an expert Review of an Experimental Crossing Signal.

Task Objective

This project was intended to accomplish three goals: (I) merging of two databases of San Joaquin Rail Corridor crossings and their physical properties, (II) demonstration of feasibility of building a database of crossing violations (which we term “near-misses”) as observed by means of a digital video data gathering system mounted in an AMTRAK locomotive, and (III) demonstration of a new in-pavement crossing signal based upon LED technology temporarily installed at a test site on the San Joaquin Rail Corridor.
