On the existence of competitions among information service providers and toll road operators

This paper investigates whether there are strategic interactions among private advanced traveller information service providers (ISP) and private toll road operators (TO), whose objectives are profit-driven. For this purpose, a multi-class stochastic user equilibrium assignment model capturing the elastic market penetration of traveller information services is developed through the nonlinear complementarity problem approach, and a numerical study is set up. The result indicates that TO and ISP can have strong interactions and be competitive in nature
