Problems solved by technology
At present, when a gathering of operating vehicles occurs, the competent authorities often only know about it after the fact, and it is difficult to effectively prevent and deal with the gathering of operating vehicles
[0003] The existing early warning methods generally judge the total number of operating vehicles in the area regularly and regularly, and it is difficult to realize the judgment of multi-level sub-areas. The information of the prompt area is not comprehensive enough, and the workload of the competent department to search for the accurate area is relatively large.

Embodiment Construction
[0035] see figure 1 , a method for early warning of commercial vehicle gathering events based on floating vehicle technology, the method includes the following steps:
[0036] Step 10. Data collection: the on-board information terminal regularly collects the serial number and location information of the operating vehicle during driving, and transmits the collected information to the data center;
[0037] Specifically: the on-board information terminal regularly collects the serial number u and the position l of the commercial vehicle at a period τ during the running process of the commercial vehicle, and obtains the driving data sequence x of the commercial vehicle with the serial number u n =, and transmit the collected data to the data center equipped with GIS system through mobile cellular communication and other technologies, where n is the number of driving data sequence x;
[0038] Step 20, maintaining a dynamic area database of the data center: the data center divides ...

The invention provides a commercial vehicle gathering event early warning method based on a floating vehicle technology. The method comprises the following steps of: acquiring numbers and position information of commercial vehicles, recording the number of the commercial vehicles in each sub regional information sequence into a dynamic regional database of a data center, executing a gathering event abnormal information discovery algorithm on each sub regional information sequence to realize early warning information analysis, and actively transmitting the detected commercial vehicle gathering information to a competent department so as to realize early discovery and positioning of commercial vehicle gathering events. The method has significance for improving the safety and the stability of the commercial transportation vehicles.
Description
【Technical field】 [0001] The invention relates to a method for early warning of gathering events of commercial vehicles based on floating vehicle technology. 【Background technique】 [0002] With the development of urban public transportation, the number of operating vehicles has increased rapidly, and the management of operating vehicles has become more difficult. At present, when a gathering of commercial vehicles occurs, the competent authorities often only know about it after the fact, and it is difficult to effectively prevent and deal with the gathering of commercial vehicles. [0003] The existing early warning methods generally judge the total number of operating vehicles in the area regularly and regularly, which is difficult to realize the judgment of multi-level sub-areas, the information of the prompt area is not comprehensive enough, and the workload of the competent department to search for the accurate area is relatively large. With the development and applica...
