The purpose of this project was to investigate the problem of vehicle entrapment at grade crossings due to attempts of making left turns to roadways which are parallel to the railroad. This project investigated selected highway-rail grade crossing on NJ TRANSIT's lines in New Jersey. Possible design ideas for solving such vehicle entrapment problems were examined using human subjects in the lab and observations in the field. The projects involved data analyses of accident records, development of an in-lab experiment for studying effect of design solutions to the performance of driver's roadway vs. railroad judgment, conducting the experiment, data analyses of the experiment, recommendations to the field validation study, selection of field study sites, conducting the field study using video cameras, data analyses for the field study, and recommendations to conclude the project. |
