Study on the Control Strategy of Parking Guidance System

The parking guidance system (PGS) is one part of ITS (Intelligence Transport Systems). At present the existing central problem is that the system control structure is ambiguous and the information of parking space issuance isn´t timely and exact; its form is single and it hasn´t the forecast function. Through the analysis for the route characteristic of big city the paper establishes the PGS control structure. Through the empty parking place analysis for the different the time period and area-parking field the paper concludes the factors that influence the parking place change. And then the paper concludes the control model of PGS information issuance. Last through the parking place data analysis for the past years parking field and considering the influence factors the paper concludes the empty parking place forecast model through Matlab simulation.
