A new car-following model with consideration of roadside memorial

In this Letter, a car-following model with consideration of roadside memorial is proposed. The numerical results show that the proposed model can qualitatively describe the impacts of roadside memorial on traffic flow and the traffic risk coefficient. It is also shown that roadside memorial can enhance the traffic safety.

► A car-following model with consideration of roadside memorial has been developed.
► We use it to explore the effects of the roadside memorial on traffic system.
► Results show that it can describe complex phenomena resulted by roadside memorial.
► Whatʼs more, considering roadside memorial can improve traffic safety.
► The results help us understand effects of roadside memorial on traffic flow.
