The service system of urban parking guidance based on GIS in Lianyungang, China

With the development of the city and the increasing personal cars, the parking difficulty has been a general problem in the urban traffic. Some Urban Parking Guidance Systems (UPGS) have been established that contain roadside changeable message boards. However, those general UPGS can´t provide personalized services, can´t combine with the electronic map, can´t show enough information. Additionally, the cost of those UPGS is very high. After analyzing the functions of UPGS and parking optimal models, we established a real-time changeable, integrate and individual UPGS, which combined with components Geographic Information System (GIS) technology, and contained the functions of information customization and message feedback. The UPGS is an effective way to solve the problem of finding parking place more quickly, to ease the crowded traffic. The UPGS has changed the traditional type of cluster information guidance method based on the roadside changeable message boards. The personalized service from the UPGS is highlighted, the parking optional algorithm is designed, and the UPGS is established ultimately. The drivers can so better master the information about spatial contribution of the parks and dynamic changes of information around the destination, that they can track the information of the interesting park continuously. The UPGS has a better dependability and can better meet the business features of parking and user information demand.
