Design And Implementation Of Parking Space Recommendation System Considering User Preference

The rapid economic development and the acceleration of urbanization have greatly improved people's living standards.To facilitate travel,more and more families have purchased cars and the number of cars has increased dramatically.At the same time,the parking needs of users are getting bigger and bigger,the parking space resources have become seriously insufficient,and the problem of parking difficulties has become more and more serious.In order to alleviate the problem of parking difficulties in the city,the number of parking lots in cities is increasing,and the scale is also increasing.The increase in parking space resources has alleviated the contradiction between parking space resources and parking needs of users to a certain extent,but it has also brought about new parking problems,that is,users do not know the distribution of free parking spaces when parking in large parking lots.It is difficult to quickly find free parking spaces that meet parking preferences and have to walk around in the parking lot.This not only causes vehicle congestion,but also wastes parking space resources.Due to the complexity of the parking environment inside the parking lot,the user is confused when parking the car,unable to know in advance the location of the empty parking space,and the parking difficulty caused by the parking environment around the empty parking space,this paper analyzes the factors affecting the user's parking preferences and designs a parking space recommendation system that considers user preferences.Based on the analysis of user's parking preferences,this paper takes the parking space recommendation as the research object,and establishes an optimal parking space recommendation model according to the user's parking preference.Among them,the parking preference includes the closest walking distance and convenient parking.The model selects walking distance and free parking space status as the optimization goal.If the user only considers the shortest walking distance from the empty parking space to the parking lot exit when parking the user,then the pedestrian distance is used as the evaluation index to recommend the nearest empty parking space for the user from the parking lot exit;If the user considers both the walking distance and the convenience of parking when parking the vehicle,the two factors of the walking distance and the free parking state are combined as an evaluation index to recommend the empty parking space having the highest integrated property value for the user.The main work of this paper is as follows:(1)Analyze the user's parking preferences.Firstly,the parking flow of whether parking spaces are recommended or parking spaces is compared and analyzed.Secondly,the main factors influencing the user's parking are analyzed,and the walking distance from the free parking space to the elevator and the free parking spaces are determined to affect the user's choice of free parking space.Influencing factors,finally introduced how to realize the calculation of the empty parking spaces recommendation and the shortest distance.(2)Establish a parking recommendation model.Firstly,the overall design of the system function is introduced.Then a parking space recommendation model is established according to the functional design.The walking distance and the free parking space status are used as the evaluation indicators for the parking spaces,and the parameters involved in the model are explained.(3)Realize parking space recommendation system.The algorithm for designing parking spaces recommendation function was used to calculate the best free parking space according to the parking space recommendation model.The Dijkstra algorithm was chosen to calculate the shortest path from the user's selected parking lot entrance to the recommended empty parking space.Thereby guiding the user to stop,and through the example to achieve the parking space recommendation and parking space guidance.The parking lot recommendation system designed in this paper mainly implements the parking space recommendation function and the parking space guidance function.The purpose is to recommend free parking spaces that meet the user's parking preferences,and at the same time,in order to facilitate the user to find the free parking space,the system provides the query from the parking lot entrance.The function of the shortest route to the empty parking space guides the user to stop and allows the user to quickly find an empty parking space.
