The invention provides a parking
guidance system regulation and control method taking parking time into account. A multi-purpose parking
guidance system dynamically displays the
road traffic condition in an area, information of
parking space of various large parking lots and information of difficulty of parking in the parking lots in a road network diagram. The parking
guidance system regulation and control method comprises the steps that parking
time information is selected as an index of the difficulty of parking in the
parking lot, wherein the parking
time information includes the parts which are the road traveling time for a vehicle to reach the
parking lot, the time for the vehicle to
queue outside the
parking lot for entrance, and the time for the vehicle to search for
parking space in the parking lot; calculation models of the parts of the parking time are built, and the mode of combination between color guidance and time publishing is selected to publish the parking
time information on a parking guidance screen through
wireless communication. According to the parking guidance
system, a driver can be helped to rapidly learn about the conditions of the
parking space in the parking slots in the area and the difficulty of parking in the parking slots, and makes a scientific and reasonable choice. The utilization rates of the parking slots can be balanced, the parking efficiency of the driver can also be improved, and the dynamic and static state traffic guidance integration design is achieved.
