Abstract:

Visitors to the 2010 Shanghai Expo will be of large amount and scale, while the road traffic infrastructure and natural environment capacity around the Expo Park is limited. If under the visitors' free traffic choice mode, the artificial transportation environment will be overloaded inevitably, and the natural environment will be polluted seriously. So the traffic environment carrying capacity in the period of Expo must be regulated and controlled according to the situation. Visitors to Expo will be of highintensity and last for a long period. The traditional regulation and control policy, which are characterized by mandatory measures, however, is generally adopted for temporary highintensity visitors, and is not adapted to the EXPO's situation. Based on the regulation and control principles of transferring from separate parts to overall situation, from mandatory method to guiding method, as well as from single variable to double variables, "Guide and Control" mode, which is used to regulate and control traffic environment carrying capacity, is brought out in this paper. The mode gives priority to "guiding", which attracts the visitors to transfer to public transportation by improving public traffic efficiency and compensating for traffic transferring. The mode also takes "controlling" as the assisting way: restricting private vehicles' entry in a certain area around the Expo Park to ensure the assembling and evacuation of visitors, and using clean fuel vehicles to diminish the influence to the natural environment.
