The Matching Of Shared Parking In Central Areas’combined Land

With the rapid development of urban economy,the motor vehicle ownership has a rapid growth,"demand supply contradiction" and "parking resources do not match" in urban parking area are becoming increasingly serious.In the face of the mixed area of the city center area,various types of buildings in the mixed land are used to take advantage of the inherent law of the parking time.Parking Shared is used to dig he potential of time and space resources of the existing parking spaces,optimize the integration of parking resources,enhance the overall utilization of parking resources efficiency.In this paper,the parking spaces of various types of buildings which have been built and put into use in the combination land are used as the research object to analyze the time-varying characteristics of parking patterns of different land types and find their inherent laws.Through the questionnaire,this paper establishes a model of shared parking behavior under different scenarios;and establishes a time and space parking match model for parking demand and supply with the purpose of improving the space-time resource utilization efficiency of the parking facilities in the combination of land to explore the law of demand distribution between different land parking types as the impedance transformation conditions,descript of the combined use of berth sharing utility quantitatively.Firstly,five kinds of land types with universal shared parking were selected.Through the investigation and acquisition of data,the parking characteristics of parking spaces,vehicle departure characteristics and parking length characteristics were analyzed to find the relationship between the parking types:grasping the time required to park the vehicle from the parking time;analyzing the basic law of the types of parking from the parking berth occupancy characteristics,effectively determine the peak demand time;mastering the vehicle floating changes in the law from the vehicle to the characteristics,getting the specific time to change the range of vehicles to determine the type of land sharing capacity,and through the "vehicle into and out of the dynamic changes" to reflect it,which as the basis matching of different land types shared.Secondly,combined with SP and RP questionnaires to determine the factors that affect the choice of parking shared behavior in face of different types of parking vehicles,including the personal attributes(age,income,driving age,etc.)and parking lot options(distance,rate Security,etc.).According to the utility theory,this paper establishes a number of parking-sharing model and random number Logit model for the long-term sharing at night,daytime sharing,and short time sharing respectively,calibrate the parameters of the models with Stata,and the random coefficient Logit is more comprehensive and accurate when solving the parking sharing options with a comparative analysis.Finally,the paper analyzes the relationship between the supply of parking berths and the demand matching in the combined land under the shared conditions.Considering the time and space occupancy of the parking lot,the concept of the parking capacity of the combined land is put forward.The method of space-time consumption is established.With the objective of"parking system space-time equalization",the optimal allocation of shared berths based on objective data is obtained.According to the calculation of parking behavior,the actual allocation of shared berths under the impedance condition is established.The matching degree index based on the optimal allocation of objective data sharing berth is established,and the matching degree of the actual berth sharing option of the parking operator is improved by the dynamic control of the impedance,and the optimization method based on the choice of the parking shared is established.
