Guidelines for the Evaluation of Dynamic Message Sign Performance

Author/Presenter: Mounce, John M.; Ullman, Gerald; Pesti, Geza; Pezoldt, Valmon
Abstract:

The objective of this research project was to determine appropriate guidelines and methodology for evaluating dynamic message sign (DMS) performance. National literature reviews and agency surveys were conducted and synthesized for a critical assessment of the state-of-the practice in DMS performance evaluation. DMS performance metrics were established based upon data availability, time of evaluation (pre-post), and environment of application (urban/rural). Both qualitative and quantitative DMS benefits were established with examples of associated analysis tools given and discussed. Case studies were conducted along freeway corridors where DMSs had been implemented in both urban (Houston, Texas) and rural (Amarillo, Texas) environments. The results of these case studies highlighted constraints in both data availability and appropriate analysis procedures. Final guidelines and methodology for DMS performance
evaluation were produced emphasizing the limitation to assessment of both qualitative and quantitative benefits. A guidebook of DMS performance evaluation procedures was included as Appendix D in the
research report.
