A new car-following model considering driver's desired visual angle on sharp curves

From the perspective of driver's visual characteristics, based on the influence of the two-point preview steering decision and stopping sight distance on the car-following behavior in small-radius curves, the new car-following model considering driver's desired visual angle on curved roads is proposed in this paper. The dynamic performance and safety of the new model are explored subsequently. First, the neutral stability condition of the new model is derived by linear stability analysis. Then, the evolution process of small disturbance of traffic flow is analyzed by numerical simulation, and the same conclusion of linear stability is obtained. That is, introducing the effect of the driver's desired visual, designing a reasonable curve radius, and the large vehicle becoming the leading vehicle is conducive to improving the stability of the traffic flow and effectively alleviating traffic congestion. Finally, the safety of the new model is analyzed by using the stopping sight distance, which shows that the newly introduced factor can also effectively improve the safety of car-following behavior on curved roads.
