Active traffic management is a hot topic for addressing issues of highway congestion . It is the use of intelligent transportation systems to provide real time traffic information on highway conditions . In Austin , the segment of Interstate 35 between Riverside Drive and State Highway 71 experiences both congestion and safety issues . This report provides an introduction into the application of active traffic management through the use of a proposed queue warning system in the area . First , select crash data on the region is highlighted to present the safety conditions , particularly the type of collision and crash severity involved . Next , a proposed queue warning system design is described . This includes a description of the equipment used , methodology for system deployment , and expected outcomes . Finally , a computer simulation testing the operational performance of the queue warning system is performed using VISSIM , and the results are reported . This report aims to demonstrate the role that queue warning system and active traffic management may play in addressing metropolitan traffic needs . |
