[0049] Below in conjunction with accompanying drawing, the present invention is described in detail: as figure 1 As shown, the dynamic division method of the urban road network control sub-area based on the macroscopic basic map described in the present invention is to form the initial division sub-area of the road section in the road network with the real-time change of the traffic congestion degree, and then complete the further detailed sub-area. divided. According to the traffic data provided, the computer can automatically select the appropriate division method, and then start the dynamic division of the road network sub-areas. The method for dynamically dividing the urban road network control sub-area based on the macroscopic basic graph described in the present invention comprises the following steps:
[0050] 1), initialize the traffic control computer:
[0051] 1.1), use VISSIM software based on the real environment, according to the basic data of the road network...
