[0051] Example
[0052] A time division method for traffic signal control schemes considering the flow imbalance at intersections, such as figure 1 , Including the following steps,
[0053] S1. Obtain intersection channelization information, traffic flow data, and basic information about traffic signal control schemes.
[0054] S11. Complete the collection of intersection channelization information for the intersection, including information such as entrance i, flow direction j;
[0055] S12. Obtain the traffic flow data of each entrance in each unit time period Clean the data. Where Represents the traffic flow from i to j in the nth unit time period, where n={1,2,...,N}, the duration of the unit time period is determined according to the intersection characteristics and traffic flow characteristics, generally 5min or 15min, N The preferred value is 288 or 96. In general, data cleaning includes abnormal data elimination (in general, abnormal data includes zero traffic flow, exceed...
