Abstract EN
In order to investigate the effect of strong wind on dynamic characteristic of traffic flow, an improved car-following model based on the full velocity difference model is developed in this paper.
Wind force is introduced as the influence factor of car-following behavior.
Among three components of wind force, lift force and side force are taken into account.
The linear stability analysis is carried out and the stability condition of the newly developed model is derived.
Numerical analysis is made to explore the effect of strong wind on spatial-time evolution of a small perturbation.
The results show that the strong wind can significantly affect the stability of traffic flow.
Driving safety in strong wind is also studied by comparing the lateral force under different wind speeds with the side friction of vehicles.
Finally, the fuel consumption of vehicle in strong wind condition is explored and the results show that the fuel consumption decreased with the increase of wind speed.
