Evaluation of freeway DMS integrated with incident management in San Antonio, Texas, found fuel consumption reduced by 1.2 percent; integrating the DMS with arterial traffic control systems could save 1.4 percent.
The evaluation report detailed benefits information regarding the implementation of an incident management program with traveler information and dynamic message signs (DMS) along a freeway corridor and traffic signal timing control operations along a parallel arterial. Through a modeling effort, the study investigated the impacts of each implementation individually, and also evaluated the combined impact of integrating the DMS with incident management and then integrating both the DMS and incident management with traffic signal timing plan alterations along an alternative arterial route.
Results indicate that the most effective stand-alone implementation is incident management, recording improvements in all impact measures assessed. DMS and arterial traffic signal control can provide additional improvement under many of these areas. For the particular corridor modeled during this study, optimum implementation of the integrated DMS and incident management result in reduced delay, fewer crashes, and a 1.2 percent decrease in fuel consumption annually. Integrated use of incident management, DMS and arterial traffic control can achieve a 1.4 percent decrease in fuel consumption for travelers in the corridor.
