A methodology for sustainable traveler information services

The provision of traveler information services in the form of route planning and guidance (RPG) often involves three parties: service providers, users, and the traffic management agency. Each of these parties has distinctive objectives that are often in conflict with each other. This study developed a mixed-equilibrium model to consider the implementation of RPG services. We modeled the market penetration of RPG services in an elastic manner and developed a methodology to study the tradeoff among these conflicting objectives. The goal is to seek solutions that can sustain. This model can also be used to investigate the sensitivity of government policies on these services. Numerical results of a small network are provided to illustrate the behavior of this model.
