Media Release Parking Information 本科畢業(yè)設計 (外文翻譯 ) 3 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。 induction system。s growing parking problem in big cities. From the parking guidance system of the angle of the overall planning and design, bined with intelligent transportation systems, discuss the establishment of a subframe structure before the trip, providing use of the Inter, munications and media, travel different channels were released before the transfer of specific functional design of parking information . Keywords: parking。s growing parking problem in big cities. Motorists to travel at the same time enjoy the freedom, they had to face due to lack of resources caused by the search for parking spaces in distress. Especially for the driving experience is short, travel, or are not familiar with a limited number of motorists who travel destination, if the destination before the trip did not understand the distribution of parking facilities nearby, it may be confused and convoluted, Park Patrol embarrassment. On the other hand, some car parks are set up in the ground, position a bit more, park paths far, newly built and other factors were not concerned about or even unknown, even in peak times, no one cares. Thus, it is necessary to prepare before the trip of Parking Guidance and Information System for simple profile. Prepare Pretrip parking information transmission system In order to meet the wishes of characteristics of drivers, taking into account the economic levels of different classes of drivers, knowledge, skills and information needs of the situation before the trip difference to modern hightech tools and 本科畢業(yè)設計 (外文翻譯 ) 2 traditional methods bined strengths to build multilevel useroriented and prehensive realtime parking information services the city before the trip information transmission system. Combined with modern hightech development trend of the future evolution of the guide, the use of Inter, munications and media transmission channels 3, subframe building before the trip shown in Figure It should be noted that the implementation of the scheme before the trip the main subsystem is twoway transmission, the subsystem can either finishing the traditional function of the passive receiving parking information, while the control center to pass the initiative to send the data, reflecting realtime parking information, and the city the ideal individual will of the user interface. Prepare the subsystem functional design before the trip To facilitate data exchange at all levels, PGIS and travel into the city before the subcentral control center, area control center, user 3 levels. The following were discussed by Inter, mun
