[0083] Such as figure 1 , figure 2 , image 3 with Figure 4 Shown, a kind of urban road hierarchical dynamic coordination control technology is characterized in that it is realized through the following steps:
[0084] Step 1 as figure 1 As shown, considering the city as a whole, urban roads are divided into ordinary road layer, ramp layer and express road layer by layering technology;
[0085] Step 2: According to S4 adjacent intersection correlation degree algorithm
[0086]
[0087] In the formula, D S(i→j) is the correlation degree of road traffic volume in the i→j direction; D C(i→j) is the periodic correlation degree between intersection i and intersection j: D E(i→j) is the number of existing associated traffic vehicles on the i→j direction road section, including the number of queuing vehicles and the number of driving vehicles, which can be obtained in real time through the magnetic induction coil set on the road section; N A(i→j) L is the maximum associa...
