An improved car-following model considering influence of other factors on traffic jam

In the Letter, a modified car-following model is presented, in which, the effects of vehicles (or non-motor vehicles) on other lanes without isolation belts are taken into account. The stability condition of the model is obtained by using the control theory method. To check the validity of the present theoretical scheme, the numerical simulation is carried out for the new car-following model, and the simulation result is consistent with the theoretical analysis.

► We propose a new car-following model considering the effects of the traffic vehicles (or non-motor vehicles) without isolation belts.
► The control theory method is introduced into car-following model.
► The numerical simulation is presented to confirm the theoretical results.
