A literature review, field study of Rectangular Rapid Flashing Beacon (RRFB) installations in Oregon, and a static survey on the sequencing of the Pedestrian Hybrid Beacon (PHB) were completed. The field study conducted in this project was designed to compare side and overhead-mounted beacons and RRFBs. The field study results indicated that the environment surrounding the crossing has an impact on compliance and that the presence of a median can increase compliance. The PHB study verified that drivers are confused about what these devices are and how they operate. For the first deployment of a PHB in an area, a public education program is recommended during the early deployment of the PHB. The Guidelines that have been developed as part of this project were based on the literature review and the Oregon field study. The major recommendation is that RRFBs be installed on medians when side-mounted devices are considered and at locations with posted speeds of 40 mph or less unless additional features such as stripping, signing , and advance warning RRFBs are used. To reinforce the guidelines, a decision matrix was developed. |
