Appertaining parking garage is the main part of urban parking facilities, so enhancing its utilization has great significance for relieving hard-parking in central area. In this study, we introduced hedonic price method (HPM) into static traffic field. Based on exploring the development and portability of this model, regional location and ministrant intention of building, garage scale, road grade at the entrance and the exit, parking fee standard, curb parking spots around garage were independent variables, average utilization of parking garage per unit-time was dependent variable, we established linear, semi logarithmic and double logarithmic model of parking garage utilization. Then, based on garage datum of Jiefangbei CBD in Chongqing, we established semi logarithmic utilization model of parking garage in the morning, afternoon and evening. The results show that: the factors which influence the utilization of parking garage are dynamic. Regional location, ministrant intention of building and curb parking are the main factors, besides, every ten curb parking spots will influence 1%~7% parking garage utilization. Finally, combined with ofregression data of the model, this paper proposed some measures and suggestions on how to enhance parking garage utilization in central area.
