Evaluation of Pedestrian and Bicycle Engineering Countermeasures: Rectangular Rapid-Flashing Beacons, HAWKs, Sharrows, Crosswalk Markings, and the Development of an Evaluation Methods Report
CHAPTER 7. EVALUATION METHODS REPORT
This chapter summaries the FHWA report, Pedestrian and Bicyclist Traffic Control Device Evaluation Methods, FHWA-HRT-11-035.(30)
Pedestrians and bicyclists are vulnerable road users when their paths cross vehicular traffic. Traffic control devices are one low-cost safety solution that can be used to better inform, warn, and regulate all road users. FHWA requires evaluations of the effectiveness of traffic control devices that are not in the 2009 MUTCD.(2) When determining whether countermeasures are effective, engineers and planners often rely on anecdotal observations or their professional judgment. In some cases, a limited quantitative safety evaluation is conducted; however, these evaluations are typically limited in terms of scope, experimental design, and statistical rigor. This is often the case because many State and local agencies lack research funds or sufficient knowledge of experimental design and statistics to conduct reliable evaluations of new innovative traffic control devices or other traffic features.
As part of this FHWA project, an evaluation methods report was developed. The report is intended to inform practicing engineers, planners, and public works employees at the local, county, and State levels how to conduct an evaluation of traffic control devices. The guidance provided, though presented in the context of devices associated with pedestrians and bicyclists, can be applied to evaluations of any traffic control device.
The goal of the Pedestrian and Bicyclist Traffic Control Device Evaluation Methods report is to improve the quality of those evaluations conducted as part of the MUTCD request for experimentation process.(30) New traffic control device products and applications are constantly being introduced, and quality evaluations are necessary to prove their effectiveness before widespread adoption. The main body of the report presents basic evaluation method steps for traffic engineers to use. More advanced methods involving crash statistical analysis and human factors studies are described in appendices to be used by consultants or university researchers working with practitioners.
