摘要：	This project was established to provide a means of conducting limited scope evaluations of numerous traffic control device issues. During the first year of the study, researchers completed assessments of six issues: dual logo panels in specific service signing, rear-facing beacons for school speed limit sign assemblies, a red border conspicuity treatment for the Speed Limit sign, crashworthiness of a work zone sign support system, retroreflective border for traffic signal backplates, and methods for locating no-passing zones. Evaluation methods included a computer-based driver survey for the dual logo panels, before and after comparisons of vehicle speeds for the rear-facing school beacon and red border conspicuity treatment for the Speed Limit sign, a crash test for the work zone sign support system, red- and yellow-light running for the retroreflective signal backplate, and a synthesis of practices for locating no-passing zones. Based on the results of the evaluations, the researchers recommend that the dual logo sign panels and the rear-facing school speed limit beacons be considered for implementation. Additional evaluations will be conducted for the red border conspicuity treatment for the Speed Limit signs. / NOTE:Technical rept. September 2003-August 2004.
