Implementation of Enhancing Curve Advisory Speed and Curve Safety Assessment Practices

TxDOT engineering study methods for setting curve advisory speeds were recently updated in Research Project 0-6960, Enhancing Curve Advisory Speed and Curve Safety Assessment Practices. The update included extending the guidance to more types of rural highways (i.e., four-lane highways and freeways) and updating the software suite used to implement the Global Positioning System (GPS)-based engineering study method for setting advisory speeds. TTI will assist TxDOT practitioners in their application of these new resources for checking and updating Texas’ curve advisory speeds, in time for the December 31, 2019 compliance date of the Texas Manual on Uniform Traffic Control Devices (TMUTCD). Researchers will develop and present webinars and workshops for TxDOT practitioners who are responsible for traffic operations and signing and marking rural highways. The research team will also provide technical support and guidance for the software suite, which consists of the executable Texas Roadway Analysis and Measurement Software (TRAMS) program and the spreadsheet-based Texas Curve Evaluation Suite (TCES)
