[0135] Example 1
[0136] Taking Beijing text alarm data and traffic flow data as examples, the process of the present invention is as follows:
[0137] 1) Preprocess the road traffic incident alarm information data, eliminate and repair abnormal data, establish a location information database of Beijing's place name address space, and obtain the location information of traffic incidents, such as figure 2 shown;
[0138] 2) According to the obtained spatial location information under the event state, classify the traffic flow data and analyze the spatiotemporal distribution characteristics of road traffic flow to map the 34,202 base stations in Beijing to the area within the sixth ring road of Beijing;
[0139] 3) Match the event location data with the traffic flow data upstream and downstream of the incident road section, analyze the impact of emergencies on traffic flow, and establish a traffic semantic classification based on mobile phone location information for commutin...
