To explore the urban expressway's capacity after a traffic incident, a capacity assessment approach based on VISSIM has been proposed, in which we disassemble the evolutionary processes of local traffic state after traffic incident and analyzed influence factors. Firstly, the ID algorithm of the decision tree was introduced, and accident delay time was solved by using information gain value. Then, according to the Traffic Flow Wave Theory, we determine the congestion dissipation time. Secondly, taking accident delay time as observation period, the maximum vehicle volume through the accident roads was considered as its capacity. Finally, it was simulated and calculated by VISSIM. The results show that, the accident delay time of vehicle anchor and the crowded dissipation time are the minimum, but the residual capacity of the accident roads was the maximum, the portion was 69.926%; the accident delay time of vehicle collision and the crowded dissipation time were the maximum, but the residual capacity of the accident roads was the minimum, the proportion was 49.963%; the residual capacity proportion of the vehicle roll-over, fire and rear-end were 56.87%, 61.611%, 59.796% respectively
