Bus information inquiry method, collection method and bus information system

Abstract

The invention relates to a bus information inquiry method, a collection method and a bus information system. Inquiry and collection of bus information can be realized in asynchronous exchange of bus information of bus participants. At first, a bus information exchange request is sent through a controlled common networking device and comprises a bus information and / or inquiry request to be exchanged. Then the bus information exchange request is received by an asynchronous bus information exchange center, the exchanged bus information is stored, and the required bus information is inquired in the relevant stored bus information which is exchanged by other bus participants according to the inquiry request in the exchange request and is returned to the common networking device. No special bus information source device is needed for bus information inquiry or the bus information system, the openness of bus information inquiry services can be maintained, costs of the bus information inquiry services can be minimized, and more diverse bus information can be provided than the prior art.

Description

technical field [0001] The invention relates to the field of traffic information, in particular to a bus information query method, a collection method and a bus information system. technical background [0002] Public transport information plays an important role for public transport participants including passengers, bus drivers and passengers (hereinafter referred to as drivers), and bus station dispatchers (hereinafter referred to as dispatchers). Timely and comprehensive grasp of bus information, including passenger waiting information and bus / boat operation information, helps passengers choose the right bus line, bus time and even the right bus vehicle, saves traffic time, and improves the efficiency of taking public transportation. Comfort, improve the proportion of green travel; understand the bus operation status, help bus drivers and dispatchers optimize bus scheduling and operation, improve bus service quality and operational efficiency. [0003] Existing bus info...

Problems solved by technology

The short message service-based bus waiting query system disclosed in Chinese Patent Publication No. CN102088678A needs to be equipped with a special on-board device or module on the bus, which is used to allow the driver or flight attendant to perform manual operations for unilaterally providing the location information of the bus Addition and subtraction stations, and the short message service is limited by the form of communication, which makes the inquiry lack the flexibility it should have, and the cost of use is relatively high

[0004] Although the above technology has solved the query and collection of bus information or other information based on vehicle location, there are more or less the following problems to be solved: First, it is necessary to configure special bus information source equipment to enable the provision of bus information services Huge investment and maintenance costs are required, which makes the cost of providing public transport information services relatively high. At the same time, the asset dependency relationship generated by the dedicated public transport information source equipment also makes the operation of public transport information services heavily dependent on the operation of public transport, reducing the cost of public transport information services. The openness of the service; the second is that the content of the bus information automatically collected based on physical equipment is relatively single. Except for the information content that is easily captured by physical equipment such as location information, it is difficult to obtain information about the health status of the bus and the congestion in the bus that passengers care about. The information about the riding conditions such as status; in addition, the existing bus system generally only collects and provides information about bus vehicles, but cannot provide information about passengers; third, the working mode of the physical equipment of the bus information source sent automatically or regularly is Synchronous, that is, the transmitted bus position information is synchronous or almost synchronous with the real-time change of the position. Although this can make the position of the bus or passengers accurate to the meter level or ten meters, on the municipal bus roads with complex road conditions, meters The measured location information is not as good as the location information marked by bus stops, which is more conducive to the formation of their own judgments and predictions by bus participants who are familiar with road conditions. In this case, the synchronous working method of obtaining bus information will not only waste the precious power of the equipment And more communication resources, occupy unnecessary bandwidth, and the availability of the information provided is lower; if the position information measured by meters is converted into the use of bus stops or bus location markers, detailed bus geographic information data is required, This increases the link of information processing and wastes a certain amount of computing resources; when this synchronous working method is applied to the physical equipment carried by passengers, the resource occupation is even more serious
