Analysis Of Parking Behavior Based On Type-2 Fuzzy Sets

At present,when the existing parking facilities are not perfect,the problems such as being difficult to park or to find parking space caused by the continuous increase of the number of motor vehicle have brought much inconvenience to people's life and work.In order to solve the problem of parking difficulties,this paper uses the type-2 fuzzy set method to analyze the parking behavior,from the driver's point of view to find the optimal parking choice to meet the driver's individual needs,which provide new ideas for parking selection research.Firstly,this article analyzes the searching parking lot's process from the perspective of the drivers and even makes comparative analysis of the parking process under the parking guidance system whether or not;Secondly,the factors influencing the parking selection were determined from the survey data of the parking behavior characteristics of the drivers and analysis of the factors affecting the parking behavior through the questionnaire.This paper mainly selects the walking distance,driving distance,safety and parking difficulty as the index of evaluating the parking space,selecting the distance of the parking lot,the service level of the parking lot and the price of the parking lot as the index of judging the parking lot.Thirdly,this article uses the type-2 fuzzy set in the time-varying universe to describe the evaluation index of the parking lot and sets its corresponding membership function,and the fuzzy comprehensive evaluation method is used to evaluate the parking lot of different parking time and obtain overall level of satisfaction in the different parking time of the target parking lots which can provide theoretical guidance for the drivers selecting the parking lot according to their preferences.Finally,the interval fuzzy comprehensive evaluation method is used to evaluate the real-time remaining parking space satisfaction level of a large underground parking lot in a certain city.The satisfaction level of the parking space is ordered according to the driver's personal preference,so as to select the optimal berth.Based on the analysis of the parking process,this article provides new ideas for evaluating and improving parking spaces from the comprehensive considerations of the main factors affecting the choice of parking from the driver's point of view and evaluation of the parking behavior by using the interval-2 fuzzy comprehensive evaluation method to select the optimal parking lot and parking space.
