【正文】 contain the mobility of the fact. Large and medium cities in China should seriously address this problem. Parking problems in our cities has bee a problem, how to make the parking lot (library) utilization, reduce interference between static and dynamic traffic and pollution, and has bee an urgent problem cities. Proposed to improve the traffic environment and the establishment of intelligent parking guidance system, and intelligent parking guidance system planning key technology research, which for a large population of large cities have a more positive farreaching significance. I have to report the contents of the 20042005 issue of Beijing39。s growing parking problem in big cities. On the one hand static and interference caused by the traffic decline in road capacity, increased transportation costs, other longterm lowspeed, idling cars on emissions of exhaust gave serious urban environmental pollution. Therefore, how to properly solve the parking problem is imminent. System characteristics and description of several related issuesAccording to the practical application of some of the issues to be resolved, the system to do a more detailed work, so that the system fault tolerance, practicality, ease and so have certain characteristics, and the scalability of the system stronger.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 顯示對應的拉丁字符的拼音字典 查看字典詳細內容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 effective provision of raw data, the data support the prediction. The database can be established with reference to the general method of establishing the database.Forecast valid parking data technology as an intelligent parking guidance system, one of the key technologies, a parking guidance system, the research focus of the researchers, the accuracy of the prediction to some extent will determine how the parking guidance system of the inducing capacity . In this paper, based on historical data and realtime data for the two neural network prediction, proved to predict good results. Method proposed for the intelligent parking guidance system laid the foundation for further research.Traffic can not do without modern city parking facilities, and stop hard
