摘要：	Incorrect turns at highway-rail grade crossings are a serious issue in traffic safety management. According to previous studies, there are five major contributing causes of incorrect turns onto railroad tracks. Among them, potentially misleading signs and pavement markings near highway-rail crossings could confuse some drivers and lead them to make incorrect turns onto railroad tracks instead of turning at nearby downstream signalized intersections. This study proposes countermeasures aimed at providing clear guidance for drivers who are approaching at-grade crossings to continue their driving and prevent incorrect turns onto railroad tracks. The proposed low-cost countermeasures include (1) elimination of potentially misleading pavement markings and signs, (2) implementation of pavement markings with guidance information, (3) extension of edge lines at highway-rail grade crossings, and (4) implementation of Qwick Kurb to prevent drivers from turning around at railroad crossings. CUTR coordinated with Florida Department of Transportation (FDOT) Central Office, Districts 1, 4, and 7 to finalize the low-cost countermeasures and select pilot study sites for a pilot implementation and evaluation. Ten at-grade railroad crossings were identified for this pilot implementation of the proposed countermeasures and performance evaluation. A detailed deployment and evaluation plan, including pilot study sites, proposed countermeasures, estimated costs, data collection plan, and data analysis methodology were provided in this report. The evaluation results and findings from the pilot implementation could provide the support and guidelines for future widespread implementation of these low-cost countermeasures at identified crossings in Florida to prevent incorrect turns of vehicles onto railroad tracks.
