Center for Traffic Simulation Studies

This paper examines the emergence of supply side competition in the advanced traveler information systems (ATIS) industry and the marketability of private ATIS. We first describe an architectural model in which the ATIS companies collect network information from their subscribers while providing them with real-time traffic information. We then turn to a simulation study of competition and cooperation under multiple private and public information agencies. This study focuses on analyzing the interaction between information agencies and its effect on traffic system performance.
