Research On The Large Parking Lots Guidance Information System

With the rapid development of urban economy and the rapidly increase of the car numbers,the urban parking problem increasingly prominent.On the one hand,stop supply can't meet the parking demand;On the other hand,many parking space is leave unused,use efficiency is low,there is mainly caused by the lack of scientific management.Due to the increased supply of parking is restricted by the land,the funds and so on,so the science park management is more and more important. So that how to balance the parking efficient among the different parks and how to improve the parking efficient of existing parking facilities are the key and difficulty in solving the parking problem.Although there is some research on the parking guidance information system,but most are regional PGIS.After the vehicle is leaded to the parking,the research about the driver how to arrive at the empty parking lot in the parking is few.As a result,based on the study of parking guidance system,this text study the parking lots guidance information system.Firstly,based on summarizing and to analyze the research theories and status of PGIS at home and abroad,this text constructed the PGIS framework.Thereby,inducting the driver who have parking demand more accuraty and more comprehensively.At the same time,it is the foundation for the studying on the parking lots guidance information system.Secondly,based on distributing the free parking spot into the weighted directed graph,this paper calculates the shortest path with the ant colony algorithm.Applying the automatic store content ark principle,every parking space is considered as a separate storage,the parking lot is regarded as a complete system,the process of the driver save/take the car is regarded as the process of saveing/taking the goods,and combining the best parking model,this paper proposes the parking lots guidance information system based on the automatic parking guidance system.Finally, taking the Xiaozhai in Xi'an for example, this paper analyses the parking situation on Xiaozhai and combines the studied theory and design thought,and offers sample designs of the parking space guidance system of the underground parking on Xiaozhai.
