In order to ensure the quality of the reconstruction project of freeway as well as the traffic efficiency without breaking down the traffic, it is crucially important to arrange the work zone length alternately by sub-ways and subsections. The simulation method of transportation is adopted for Microscopic of the transportation situation under various length of work zone. Based on the results of the simulation, the stability, efficiency and safety of traffic flow are evaluated and analyzed comprehensively. The balance point among these three factors is determinated by the method of fuzzy comprehensive evaluation. Combined with the project cost, construction cost saving and other factors. to get the reasonable construction segment length reference value. Finally, G4 freeway (Beijing to Hong Kong and Macao) is selected as a case study.
