【正文】 g Information Media is an important part of the information society, the status of her unique channels of information will naturally attract a number of fixed and non fixed public attention. Although due to its own constraints, the media in general, there is dynamic information updates slow, realtime delay, oneway transmission, and other weaknesses, but its influence is still with usual enough to play released to supplement the information in the form of Parking. Abstract With the rapid increase in demand for city parking, long hidden in the deepseated urban parking problems have bee increasingly apparent, as the intelligent traffic system, an important ponent of the intelligent parking guidance system has bee a modern urban traffic management can not or missing key elements, and one of the important parameters of the system an effective parking system data to predict accurately is a prerequisite for successful operation. There is no mature technology as can learn, how to predict the effective data issues bee a parking place in front of the researchers, a technical difficulty. After a long study authors presented data to predict effective method of parking for a successful solution to this technical problem provides a guideline. Introduction Is well known that the acceleration of urbanization process has brought the urban population explosion, and the sharp decline in tariffs on imported cars the automotive industry in China will inevitably bring about great development of the yearly increase in car ownership, so these will lead to the rapid increase in demand for city parking. Yet Longterm parking is not received due attention, parking facilities planning lags, chaotic management, construction by the shortage of land, shortage of funds constraints, resulting in a lot of cities parking is currently the obvious contradiction between supply and demand, parking has bee a serious problem of urban traffic problems. Intelligent transportation system as an important ponent of intelligent parking guidance system will participate in the city39。s traffic management, it can manage the parking situation and the regional share of the overall coordination of the situation, for different prices to different parking areas indirect control of parking demand and balance. It can also use a variety of ITS technologies and means to achieve the parking lot of modern management, dynamic to provide for the travel to designated areas near the parking spaces / parking fees and other information types and for the driver to choose the correct car park to provide decision basis. Thus, intelligent parking guidance system to the modern urban traffic management has bee an integral part of one of the key elements. Currently, the Intelligent Parking Guidance System is booming. One of the important parameters of the system as a valid parking data system can accurately predict a prerequisite for successful operation. There is no mature technology as can learn, how to predict the effective data issues bee a parking place in front of the researchers, a technical problem. This thesis is based on the research project in Jilin Province Science and Technology Commission, Parking Youdao system model and the applied technology in the parking spaces on the effective part of the data written forecasting techniques, the paper proposed the method for the research project laid the foundation for the smooth . The meaning of effective parking Intelligent parking guidance system, the effective parking is corrected in the open public parking lot is not occupied by vehicles or other items can be used to park vehicles in 顯示對應(yīng)的拉丁字符的拼音字典 查看字典詳細(xì)內(nèi)容3 Fuzzy Neural Network Based on the effective parking 4 parking spaces effective data collection and transmission 5 cities in the parking lot of the establishment of an effective parking database and application It should be noted that the establishment of a wide range of intelligent allround play of parking guidance system, the city parking in the parking lot of the effective establishment of the database is essential. Dedicated and effective city parking parking should reflect the establishment of the database the following three principles: (1) The establishment of the database should be reflected in all car parks, city parking data valid historical data. (2) database design should be as large as possible in the time reflected on the length of a valid parking parking lot of historical data. (3) the database should be designed to better support the database management, access to applications such as basic operations. The database was created to provide a parking guidance system required the user access to designated car parks, parking data valid historical data can also be parking for the eff
