Abstract:
It has been perceived that the travelers do not respond to the incident messages on the dynamic message signs in the Las Vegas area in Nevada. The objective of the study is to evaluate whether dynamic message signs (DMS) in the Las Vegas freeway systems have been effective in distributing incident/traffic information. Specifically, this study investigates whether incident/traffic information can be distributed to the motorists in a timely manner: at the right time and at right location and in the right format. A literature review is conducted to see how dynamic message signs have been used effectively in other cities in the U.S. A tour to the traffic management center, the Freeway and Arterial System of Transportation (FAST) is made to observe the operations of DMSs. The performance of DMSs in providing traffic information to allow travelers to take alternative route is evaluated based on comparing the congestion progression and the activation of DMSs. A survey to travelers in the Las Vegas area is also conducted. Based on the investigations, it is concluded that (1) incident information should be provided earlier; (2) more relevant information on incident should be provided; and (3) more reliable information should be provided. Based on the conclusions, it is recommended (1) developing a computer aid system for using dynamic message signs in traffic management, (2) improving on the messages on incidents provided on DMS, (3) improving the reliability of travel time information provided on DMS, (4) improving the data system in incident management in FAST, and (5) conducting a study on locating the DMSs on the Las Vegas network.
