Abstract
The invention provides a method for collecting public traffic congestion status information in real time. The method comprises the following steps: firstly, a public bus provided with a vehicle-mounted information terminal collects the public number, time of pressing the key for reminding congestion and the position and the like at regular intervals in the running process of the public bus, and sends the information to a public traffic data service center through techniques such as mobile cellular communication and the like; then, the public traffic data service center judges whether the public traffic is congested at each position according to the corresponding information of time of pressing the key for reminding congestion in the data information uploaded by the public bus so as to obtain a real-time public traffic congestion status information set, and obtains corresponding public traffic information sequences by being combined with the public bus number and public bus position corresponding to the subset of the real-time public traffic congestion status information set; and finally, the public traffic data service center stores the obtained public traffic information sequences into the database of the public traffic data service center, so as to complete the collection of the information of the public traffic congestion status information in real time. In the invention, the method for collecting the public traffic congestion status information with low cost is realized.
Description
[technical field]
The present invention relates to the IT application.Specifically relate to the acquisition method of the real-time public transport congestion state information of car working application, make things convenient for the penetration and promotion of public transport congestion state acquisition system and application thereof.
[background technology]
Whether certain public transport crowded now? Where crowded? This is public's go off daily question of common concern, and people go on a journey and judge the public transport congestion status according to the experience of riding mostly at present, can't accomplish the real-time accurate information of blocking up that obtains public transport.Be exactly some public transport congestion status of query site that the user logins the public transport data service center in addition at present, but such Query Result can not feed back the congestion information of real-time public transport.
A kind of " public transport transportation regulator control system and regulate and control method thereof " is provided in the prior art; Its open day is 2008.06.11; Publication number is the Chinese patent of CN101197079, the public transport transportation regulator control system of this invention, and it is characterized in that: it is to be made up of following structure: car-mounted terminal equipment; Be installed on each bus, move, be used for personal information in the vehicle and traffic information are exported to the mobile data communication apparatus at any time with car; The mobile data communication apparatus; Be used to receive the information of car-mounted terminal equipment input, and the information of car-mounted terminal equipment input is exported to public transport company's regulation and control center microprocessor; Public transport company's regulation and control center microprocessor; Be used to receive the information of mobile data communication apparatus input; If this information is that patronage is many, the number of waiting for bus on the road is many or patronage and road on the number of waiting for bus all many; Then send control signal and give the microprocessor of each public bus network management station; Each public bus network management station sends two cars after receiving this control signal simultaneously.The public transport of this invention transportation regulate and control method is characterized in that: it comprises the steps: that car-mounted terminal equipment exports to the mobile data communication apparatus at any time with personal information in the vehicle and traffic information; The mobile data communication apparatus receives the information of car-mounted terminal equipment input, and the information of car-mounted terminal equipment input is exported to public transport company's regulation and control center microprocessor; Public transport company's regulation and control center microprocessor receives the information of mobile data communication apparatus input; If this information is that patronage is many, the number of waiting for bus on the road is many or patronage and road on the number of waiting for bus all many; Then send control signal and give the microprocessor of each public bus network management station; Each public bus network management station sends two cars after receiving this control signal simultaneously.This invention has improved the automaticity of public transport company's transportation management, solved the public transport peak period when crowded to people bring constant, especially the Ms has thoroughly solved the problem that the Ms is harassed with taking advantage of a car.But the cost that the technical scheme that should invent realizes is than higher, and the step of realization is also more loaded down with trivial details.
