Abstract:Implementing safety countermeasures on rural horizontal curves to address speeding can improve the safety performance for those locations. State safety and traffic engineers are faced with making decisions on what type of technology to use and which sites to use the technology on in a fiscally constrained environment. The research conducted for this project evaluated a Sequential Dynamic Curve Warning System (SDCWS) that could be an additional tool for these engineers to use either separately or in combination with other countermeasures to address horizontal curve locations with a history of safety concerns. TAPCO provided the SDCWS evaluated in this project and provided installation and maintenance support to the DOTs. A summary of the full report is available as a separate document (report no. FHWA-15-CAI-012-A). This project was undertaken in 2011 by the Federal Highway Administration’s Highways for LIFE Technology Partnerships Program, a discretionary program of SAFETEA-LU (Public Law 109-59). The purpose of the program is to evaluate, document, and disseminate the performance results of promising innovative highway safety technologies that are commercially available through a partnership with general industry and state and local highway agencies.
