This paper uses stochastic optimization techniques to minimize the fuel consumption of a vehicle under uncertain traffic speed. Minimizing the fuel consumption of a moving vehicle can be formulated as an optimal control problem that determines the speed profile that the vehicle should follow. The fuel consumption is affected by speed, acceleration, and external parameters such as road grades and speed limits. In addition, surrounding traffic conditions, and in particular traffic speed, may prevent the vehicle from following the optimal speed profile and consequently affect the fuel economy and the journey time. Uncertainty in the traffic speed will affect the optimization of fuel-economical speed profiles, which has seldom been investigated in the literature. This paper describes stochastic optimization models with chance constraints for minimizing the fuel consumption of a vehicle traveling over a given stretch of road under a given time limit, where the traffic speed is assumed to be random and follow a certain probability distribution. Computational results are presented to evaluate the performance of the proposed models and assess the impact of traffic speed uncertainty on the desired speed profiles. The results affirm that uncertainty in traffic speeds can significantly increase the fuel consumption and the journey time of the speed profiles created by deterministic model. Such impact can be mitigated by incorporating the stochasticity at the planning stage using the stochastic optimization models described in this paper.
