Advanced traveler information systems (ATIS) for traffic management of Tehran road network
Author(s):
Abstract:
The advanced traveler information systems (ATIS) are designed to be efficient in many aspects such as helping users in making travel route choice decisions, alleviating road congestion and enhancing network performance. These systems can propose a variety of information to users due to their criteria and objectives. In this paper, to enhance the performance of the network, it is assumed that all of the vehicles in Tehran network are equipped with ATIS and the information of system optimal (SO) routs is proposed to the users. travel times of some suggested paths are more than those of the shortest paths of the network, simply a portion of the users follows the information while the other uses the shortest paths. Accordingly, users are divided into two groups, and assigned to the network based on system optimal and user equilibrium, respectively. An iterative method is presented for assigning the demand of both groups simultaneously based on extending the well-known Frank-Wolf algorithm. Moreover, a sensitivity analysis of total travel time and average travel speed is performed regarding the different percentages of using the information of routes.
