Summary
This document is a research project capsule describing a study that has not yet been conducted. The text explicitly outlines a future timeline, stating a start date of November 1, 2016, and an end date of October 31, 2018. It details the planned methodology, including the selection of eight test locations, the installation of video-based data collection systems, and the subsequent installation of signage, all of which are described as actions the research team "will" undertake. Because the document describes a study that was in the planning or early initiation phase at the time of publication and does not report on completed experiments or findings, it falls under the category of a project proposal or synopsis. SKIP The study evaluates the effectiveness of regulatory and warning signs on driver behavior near highway/rail crossings, where stopping traffic queues can extend over the tracks; more than 5,000 at-grade highway-rail crossings in Louisiana are in scope.
