A Two-User Travelers Game Model Based on ATIS

Advanced traveler information system (ATIS) have been put forward as possible solutions for reducing congestion of metropolitan cities. The traveler behavior model is the key point on research of traffic flow in ATIS. There are three kinds of ATIS market: the complete ATIS market, incomplete ATIS market and non-ATIS market. In different ATIS markets, we consider different two classes of drivers. A two-user Travelers Game Model was build and the equilibrium of such model was discussed. The solution of Bayesian equilibrium was studied in the incomplete ATIS market and non-ATIS market. In the complete ATIS market, Nash equilibrium is analyzed. In this paper, a two-user traveler game model was proposed under ATIS in a three-route road network. This paper compared expectation of total travel time under different ATIS market penetration. Then we found that more market penetration of ATIS didn't mean less total travel time, and whole expectation of travel time in network firstly went up and then went down while market penetration of ATIS was increasing. In the end, this paper presented several emerging research in the issue of travel game.
