Vulnerable Road User Safety Enhancements for Transportation Asset Management
MetadataShow full item record
Chang, Carlos M.; Rodriguez, Edgar D.
Safety of Vulnerable Road Users (VRU) is a problem of global magnitude since the proportion of fatalities represents more than half of the total deaths in traffic worldwide. VRUs are pedestrians, cyclists, and motorcyclists of all ages and abilities. Roadway assets play a significant role in traffic safety. Pavement markings, sidewalks, bikeways, medians, guardrails, and road lighting influence in the outcome of adverse traffic accidents. This research report describes a framework that explicitly incorporates VRU safety into Transportation Asset Management (TAM) practices. The framework should serve as a guideline for State Departments of Transportation (DOTs), Metropolitan Planning Organizations (MPOs), and local agencies. The framework includes a methodology to prioritize infrastructure projects using the Dynamic Bubble Up (DBU) technique for funding allocation and a Vulnerability Road User Safety Index (VRUSI). The TAM-VRU framework and methodology applies to all VRU groups, although VRUSI is developed for pedestrians due to the sustained uptrend of fatalities registered in the last decades. Safety indexes to assess specific risk factors of other VRU groups can also be incorporated in the overall framework.
