Parking sharing means that privately and publicly owned unused parking spaces are shared by other people, which allows parking spaces to be used more efficiently. This is an innovative smart parking policy that can mitigate parking problems in high traffic urban areas. In order to facilitate parking sharing system, a convenient user environment should be created with securing sufficient parking spaces. Also it is necessary to study on customized parking information provision that reflecting the needs of users about the parking information providing through the parking sharing platform. In this study, importance factors (loading factors) on parking information requested by drivers are analyzed first using Structural Equation Model (SEM). Then based on the results of SEM analysis and users satisfaction analysis, the priority of customized parking information that have higher importance rate but lower satisfaction rate are suggested through Importance Performance Analysis (IPA). The result shows that the parking informations plotted in the 2nd quadrant are parking fee level, parking space size, parking fee information, number of parking space availability, transfer convenience, number of transfer parking lots, parking lot congestion level and waiting time for parking.
