ABSTRACT

The determination of the traffic impact area is not only the basis of traffic impact analysis (TIA), but also one of its difficult issues. At present, the foreign subjective methods not suitable in China. Meanwhile, the domestic model methods have difficulties in calibrating parameters and are over-idealistic in road assumptions, so that they are too hard to be widely used. While, this paper propose method that based on travel time reliability. Firstly, it quantifies the factors of traffic impact area to get the travel time reliability function. Secondly, it demonstrates the overall process of this method to determine traffic impact area. Thirdly, it establishes traffic assignment model. Fourthly, it takes a practical developing project in Beijing as an example to verify its maneuverability and flexibility. Finally, it compares and analyses the benefits and drawbacks of the method and other methods. In conclusion, it is reasonable to say that this method is more suitable for the actual roads, easier to operate and has important practical significance.
