Many car-following models with their own merits have been proposed to explore various traffic problems,but researchers have rarely used vehicle’s performance to evaluate them.In this paper,we study each vehicle’s fuel consumption of the optimal velocity model,full velocity difference model,full velocity and acceleration difference model and the car-following model with consideration of the traffic interruption probability under two traffic situations,respectively.The numerical results show that the car-following model with consideration of traffic interruption probability can reduce vehicle’s fuel consumption in the two studied traffic situations and thus improve the vehicle’s fuel economy.
