The work proposed at this site would include installation of instrumentation to monitor the surface condition and detect the speed of approaching vehicles. A vehicle approaching at speeds inappropriate to surface conditions would receive a warning of excessive speed. The system would communicate road conditions to SDDOTs Road Condition and Reporting System (RSRS), the database for 511 Travel Information and other information systems. The system must therefore comply with National Transportation Communications for ITS Protocol (NTCIP) standards for communications with roadside equipment and environmental sensor stations.
This project entails developing plans and specifications for the system, and installing it by maintenance or under a separate installation contract. SDDOTs future RSI reviews will determine how much accidents decrease.
