Preliminary Exploration in Choice Behavior of a Parking Lot in a S/M City with a Logit Model

In recent years, along with the amount of our country's vehicle increasing year by year, the downtown areas or CBDs in many S/M Cities have appeared parking problems. To provide some effective decision-making reference for traffic management, this article tries to help S/M City find a method to solve its urban parking problem by studying persons’ parking choice behavior. We have made the parking behavior surveys about 3 ground parking lots and 2 underground parking lots in Dazhou city, a S/M City in the east of Sicuan Province, and analyzed surveys data to regard the Saturation of Berth as a leading indicator, the distance to destination and the parking fee as two main factors that affect parking choice behavior. On basis of research we established the Binary Logit (BL) models to quantitatively depict the parking behavior. And according to the coefficients in model and the symbols of t value view, under the premise that the confidence level of t is 95%, the BL model owned a high precision. Finally, based on the qualitative analysis of parking fee, the article got a preliminary threshold of parking fee: the basic fee is 7 yuan/h, and when the parking fee exceeds the value, it has significant effect on adjusting the ground and underground parking lot choice behavior in Dazhou urban area.
