Implementation of the Visual Interactive System for Transportation Algorithms (VISTA) in the United States
نویسنده
چکیده
This paper presents the functionality of the Visual Interactive System for Transportation Algorithms (VISTA) that utilizes a mesoscopic/microscopic simulation called RouteSim and a Dynamic Traffic Assignment (DTA) routine to emulate the behavior of individual drivers and how they distribute themselves into the transportation network. The principal output of the model is the path chosen by every driver to go from their origin to their destination, and the corresponding departure and arrival time. The paper presents the application of VISTA to evaluate: 1) Intelligent Transportation technologies such as the location of variable message signs, detectors, route diversion plans; 2) Traffic Operations such as signal timing plans, transit signal priority plans, flooding, weather conditions; and 3) Short term and Long term transportation planning such as construction plans, addition/deletion of lanes or roadways, addition or improvement of roadway interchanges. A sample of projects where VISTA has been implemented in the USA is presented.
