Abstract:

In view of the inefficiency in road network travel and the excessive fuel consumption caused by it, based on the analysis of vehicle fuel consumption model, the minimum fuel consumption model of multi-vehicle was established from the perspective of energy saving and consumption reduction. Then the optimal pricing equilibrium model of multivehicle was proposed to control the user’s route choice behavior by road pricing, so that users could travel in accordance with the expectancy of road capacity, and ultimately achieved the goal of minimizing the total fuel consumption when road network equilibrium attained. The FrankWolfe algorithm was used to solve the problem iteratively by finding feasible descending directions. Taking an abstract highway network in a certain area as an example, the results show that it is possible to effectively control the user’s route choice behavior by the reasonable road pricing strategy and achieve the goal of minimizing the total fuel consumption.

Key words: fuel consumption model, road network, multi-vehicle, road pricing
