The primary objectives of this research project were: (1) to develop an active advance warning device (AAWD) comprised of an actuated flashing beacon supplement to a conventional SCHOOL BUS STOP AHEAD sign (S3-1) and (2) to evaluate its effect on driver performance and safety through school bus loading and unloading zones. Secondary objectives were to summarize system components and costs, develop an activation strategy, review the liability risk, review national experience related to safety, and provide guidance regarding specifications and use in Texas. With respect to safety, 37 of 46 studies reported a positive effect resulting from AAWDs. Findings from field studies conducted in Texas also suggest favorable results with confirmed reductions in vehicle approach speeds when the flashing beacon was activated. Costs for the final AAWD are estimated to be 2,000 dollars for the S3-1 sign and flashing beacons and 2,600 dollars for the flashing beacon activation system, not including sign installation or ongoing maintenance and operations costs. A review of published literature and historic case law suggests minimal additional liability risk above what is already experienced by transportation departments. Unique areas of risk relate to "jurisdictional responsibility" for establishing, operating, and maintaining school bus loading and unloading zones and the hazard expectation tied to the flashing beacon activation (i.e., motorists may not exercise the same degree of caution when the bus is not present and the beacons are not flashing despite children being present at the bus stop). Given the favorable safety impacts, the low system cost, and the minimal additional liability risk incurred, the AA WD is recommended for further implementation.

This project focussed on the issue of pedestrian safety devices for school buses. A previous phase provided a better understanding of the risks children are exposed to when getting on or off a school bus, and resulted in the development of an evaluation tool to determine the advantages of advanced pedestrian detection systems (APDS) for school buses.The purpose of this project was to review and validate the assessment criteria for APDS use around school buses defined in the previous phase, and to develop testing protocols that can be used at a later date when specific devices have been chosen for testing.The main tools validated and/or developed for this project were:; a fault tree to identify and quantify the risk that a child will be struck by the school bus;; broad categories of criteria comprising risk factors of the same type, weighted proportionally to their value in preventing an accident;; a theoretical evaluation grid to quantify the performance of detection devices. Laboratory, closed-track and road testing procedures were also developed. The proposed laboratory testing procedure emphasized the difficulty of devising universal tests for all types of safety devices. The report also contains a user's guide to facilitate use of the evaluation grid.

This report will be of interest to managers of public transportation and school bus systems, transportation planning and operations professionals, policy makers, and others interested in the potential for coordinating or integrating school bus and public transportation services in non-urban areas. The report identifies and discusses issues associated with such coordination or integration, and provides 13 case studies of communities that have successfully coordinated or integrated some aspect of school and public transportation services. The report also provides an implementation guide that suggests "next steps" for non-urban communities seeking to give serious consideration to the coordination or integration of school and public transportation services.
