Title:

Systemic Safety Analysis of Extended Highway Corridors

Abstract:

The present paper discusses the Virginia Department of Transportation (VDOT) approach for systemic safety assessment of extended highway corridors. This procedure, named “Corridor Safety Assessment (CSA),” was developed to assist the Highway Safety Improvement Program (HSIP) in identifying appropriate systemic safety treatments and promote a mobile evaluation methodology that maximizes the safety of the field review team and the amount of roadway covered. The CSA process utilizes a joint analysis of crash statistics, roadway features, and findings of experts’ field observations which maximizes validity of safety assessment and recommendations. The method includes a detailed procedure for complex safety assessment of the travel environment, considering impacts of the roadway, roadside, and traffic control features. This approach provides data for selection of applicable safety improvement countermeasures including both long-term high-cost, as well as immediate low-cost treatments. Analysis of the variety of risk factors also allows the selection of effective systemic improvement strategies. Formalizing the use of video and GPS logging provided an efficient way to collect information. To ensure linear references for data obtained from video records and the GPS data, a special technique to tie video frames and highway mileage was developed. Additionally, linear references of the obtained findings permit planning and programming level cost estimates of the recommended safety improvements.
