Research on Virtual Emergency Lane Modeling of Expressway Based on VISSIM
In order to solve the traffic safety problems caused by the increase in the scale and quantity of expressway construction,the working principle of virtual emergency lane was studied,and the driving rule model of expressway based on virtual emergency lane was established,and the control strategy model of virtual emergency lane with different number of lanes was constructed in different time periods of accident emergency rescue.The simulation results show that the model can shorten the average travel time,reduce the average queue length and the average delay,improve the efficiency of accident rescue,and provide ideas and directions for the construction of expressway rescue system.
