An extended visual angle car-following model considering the vehicle types in the adjacent lane

In the real two-lane traffic environment without isolation belt, changes in vehicle type in the adjacent lane will have an impact on the driver's following behavior in the lane. Due to changes in the vehicle type in the adjacent lane, we improve the full velocity difference model and present an extended visual angle car-following model. From the perspective of stimulus-response framework, the model takes the visual angle and its rate of change in front of the same lane and adjacent lane as stimulus factors, the stability condition is obtained through linear stability theory. The results indicate that the vehicle type in the adjacent lane has great impact on the stability of traffic flow. The results of numerical simulations also verify these theoretical analysis.
