Description
Technical field
The present invention relates to the transport information apparatus field, particularly a kind of city pedestrian traffic intelligent steering system.
Background technology
Present stage, technical field of information processing presented two kinds of development trends: a kind of is towards extensive, non-standard, hypermedia information, makes computer system possess the ability of handling wider information; Another kind be with artificial intelligence further combined with, make computer system process information more intelligently.Intelligent Information Processing is the forward position cross discipline in the computer science, is the application-oriented comprehensive branch of learning, and its target is to handle magnanimity and complex information, studies new, advanced theory and technology.Many levels such as fundamental research, applied basic research, gordian technique research and applied research are contained in Intelligent Information Processing research.It not only has very high theoretical research to be worth, and all has very important meaning for the development of national information industry and even entire society's economic construction, development.
Traffic guide comprises dynamic guiding and static guiding.Dynamically the information of guidance system issue airfield equipment adopts LED (Light Emitting Diode is called for short LED) display technique.Static guiding adopts various traffic signs and graticule that traffic guide information is provided.Both cooperatively interact, and play a role jointly.The expert of Communication and Transportation Engineering institute of Tongji University points out: the International Horticultural Expo Garden traffic guide must take into full account the interlock of dynamic and static traffic and induce.
In the intelligent transportation system at home and abroad, be that service object's traffic guide system has obtained first developing with the vehicle.Such as, aspect the public information guiding, the driver is by receiving radio broadcasting, and the LED traffic guidance screen in roadside is its indication the place ahead real-time road; Aspect the individual information guiding, the positional information that provides by analysis GPS (Global PositioningSystem is called for short GPS) is provided mobile unit is driver's navigation.
The technological core of the dynamic route inducible system of high-intelligentization (Dynamic Route Guidance System is called for short DRGS) depends on the optimal route selection algorithm, is the research focus always, and new algorithm continues to bring out.These algorithms differ from one another at aspects such as space complexity, time complexity, easy implementation and ranges of application.At present, the part of Real-time Traffic Information covers, and the information content is single, and is imperfect, and is dynamically pseudo-; The disunity of map of navigation electronic form, standard, software platform is to cause China to have one of reason of very big gap with the U.S., Japan and European Union aspect dynamic route planning.
But, the traffic guide system that with pedestrian is the service object does not at home and abroad obtain paying attention to and development at present as yet, in places such as large hospital, school, theme park, have only some simple and crude circuit direction boards, can not detailed route information is provided and be that the timely enquiring route of pedestrian is provided convenience to the pedestrian, particularly in as large areas such as Beijing Olympic Games, Shanghai World's Fair if there is not an electronics index map
Summary of the invention:
In order to overcome the defective of prior art, the invention provides a kind of city pedestrian traffic guiding intelligence system, a kind of city pedestrian traffic intelligent steering system is provided, this system is aspect municipal intelligent traffic pedestrian information guiding, have stronger perspective, its personalization, interactive mode, intelligent feature have embodied the characteristics that intelligent transportation is led.
Technical scheme of the present invention is as described below:
