The freeway incident delay calculation model is generally based on freeway capacity, reduced freeway capacity, traffic flow rate and incident duration. Now, it is difficult to obtain traffic flow on-line data in China because the freeway traffic flow detection equipment is scarce and most types are not available. On the other hand, the Chinese freeways are all toll roads which have entry and exit toll stations, so this paper proposes a method to analyze the traffic flow rate and the vehicle travel time by using the toll data in the freeway network and further to study the traffic incident delay. Finally this method is validated by the deterministic queuing delay model.
