Red-Light Running and Limited Visibility Due to LTV's using the UCF Driving Simulator Final rept

摘要

The UCF Driving simulator was used to test a proposed pavement-marking design. This marking is placed upstream of signalized intersections to assist the motorists with advance warning concerning the occurrence of the clearance interval. The results of the experiment have indicated promising results for intersection safety. Firstly compared to regular intersections, the pavement marking could result in a 74.3 percent reduction in red-light running. In comparison, the pavement marking reduced the number of occurrences where drivers chose to continue through an intersection when it was not safe to proceed compared to without the marking, and this result is correlated to less red-light running rate with marking. According to survey results, all of the tested subjects gave a positive evaluation of the pavement-marking countermeasure and nobody felt confused or uncomfortable when they made stop-go decisions. In comparison between scenarios without marking and with marking, there is no significant difference found in the operation speeds and drivers brake response time, which proved that the marking has no significantly negative effect on driver behaviors at intersections.
