Description
Technical field
The present invention relates to technical field of intelligent traffic.More particularly, the present invention relates to a kind of urban public transport releasing inquiry system.
Background technology
At present, the domestic exploratory stage being still in the real-time Bus information releasing inquiry of multimode, attempting the various realisation stronger releasing inquiry mode of exploitation, as set up public transport website, introducing electronic stop plate, mobile phone is installed trip query software etc.Because various mode respectively has feature, for different areas, city, can select according to condition.
Meanwhile, along with popularizing of internet, user increases, and website has become an audient and led very high distribution platform.Its maintenance cost is low, releases news convenient, and renewal speed is fast, and resource sharing is convenient, can imagery, specific represent road conditions, make user more directly, more fully can understand road network situation, and can not extra cost be produced.
Handheld mobile device mainly refers to the equipment such as mobile phone, palm PC, portable game machine PSP, itouch, ipad.Wherein mobile phone is one of typical, the most universal a kind of handheld device, end 2011 the end of the year China's mobile phone hold rate and reach 73.6%, and this numeral is still rising year by year.Along with development in science and technology, smart mobile phone prices, by most of people are accepted, improves the possibility that it becomes traffic releasing inquiry instrument.Smart mobile phone is provided with operating system, built-in multiple programs, feature richness, can install arbitrarily, uninstall, expands cell-phone function.Smart mobile phone can realize wireless network access by mobile communication network, surf whenever and wherever possible.User inputs the public bus network wanting to inquire about in mobile phone, very soon about the information such as the up-downgoing working line of this circuit, on the way website, map orientation all show; The public transport line of all marks " asterisk " can also show position and the number-plate number of all operational vehicles instantly, i.e. the real-time information of operational vehicle.User can select the public bus network paid close attention in systems in which, specifies website of getting on the bus, and system will inform that user is apart from getting on the bus the nearest vehicle of website distance leaving from station, and can represent on map, and this system can also estimate arrival time and pre-reception centre.
At present, what China's major part bus stop used is still traditional common station board, only show this circuit bus the fixing static information of the website of process, first final vehicle hour and admission fee etc.For nowadays carry most of passenger flow, becoming the bus of major public transportation trip instrument, only provide static information obviously can not provide enough services for passenger, add the civic travel time.Electronic stop plate is existing abroad to be promoted, and China also started progressively to develop in recent years, and based on level forecast of standing, come into operation in multiple cities such as Shanghai, Hangzhou, Nanjing, Shenyang.Electronic stop plate can be real-time all kinds of transport information is provided, except the essential information such as bus routes, name of station, also can show current vehicle position, with this stop spacing from, at a distance of website number and the information such as to reach after how many minutes, along with the progress of science and technology, probably also can provide the degree of crowding in car, vehicle condition, section situation etc., to user's synthesis judgment in the future.
No matter be traveler first time coming a unfamiliar city, still ride in a bus traveler on and off duty everyday, all needs the relevant information of transit trip, to plan optimum trip mode, travel time and traffic path etc.User not only needs static information, is more dynamic traffic state.And go back the unified public transport releasing inquiry system of neither one at present, and electronic stop plate, mobile phone A PP etc. also do not popularize, and the information source issued is also inaccurate not in time, the public transport Static and dynamic quantity of information that passenger can be known is little, usually " can only trust to chance and strokes of luck " at website, and the multidate information of mass transportation facilities cannot be known in advance, the traffic imbalance between supply and demand of trip is still unresolved, causes passenger to go on a journey inconvenience.
Summary of the invention
An object of the present invention is to solve at least the problems referred to above and/or defect, and the advantage will illustrated at least is below provided.
A further object of the invention is to provide a kind of urban public transport releasing inquiry system, and this system thinks that, for the purpose of traveler trip service, from the angle of traveler, the integration stress selecting user to be concerned about is issued.For traveler, have larger dirigibility in the selection before travel can done, traveler, according to the traffic of reality, selects best trip mode and trip route.Therefore, by urban public transport releasing inquiry system, the traffic-information service provided coordinates the contradiction of traffic supply and demand fully, to reach the optimum balance of traffic supply and demand.Delivery system needs to provide show the time of running of bus to user, route map, omnidistance travel time, omnidistance range ability, expense situation, delay time at stop, number of transfer, website wait the degree of crowding in duration, car, vehicle condition, section situation, weather condition and important service facility, buildings etc. on the way, allows user understand basic traffic.Inquiry system is mainly for user individual service, the origin and destination determined for user, travel time and available bus trip instrument, in conjunction with current road network situation, during prediction trip through the degree of crowding of route, search out the best route and the second route combination, and inform user in time when road conditions are different with former prediction case, arrange trip ahead of time to make user.
The information content that urban public transport releasing inquiry system provides is varied, releasing inquiry information is divided into before travel by this inquiry system from the time, trip in two classes, in two category informations, be divided into again essential information and customized information.Essential information, mainly towards the joint demand of most of audient, provides basic information service; Customized information provides service for each trip individuality, and it is a series of policy service that it is formulated that traveler can obtain dispatching center's information platform by releasing inquiry system.Inquiry system of the present invention solve passenger go on a journey inconvenience technical matters.
