Evaluation of Rural Intersection Treatments

Various intersection treatments, such as overhead flashing beacons, have been used to alert drivers to the presence of an intersection but the effectiveness of the various treatments is not well documented. Overhead beacons have been widely used to warn drivers that an upcoming intersection is present. Overhead beacons also remind drivers of who has the right of way. In general, overhead beacons have shown mixed results. In order to accomplish the research objective the following tasks are proposed: Task 1: Summarize effectiveness of standard and innovative intersection treatments. Task 2: Form TAC. Task 3: Identify and select treatment and control sites. Task 4: Collect and reduce before data. Task 5: Apply treatments at test sites. Task 6: Collect and reduce after data. Task 7: Analyze data. Task 8: Document results.
