Optimization design of parking lot layout: taking Panzhihua Wanda outdoor parking lot as an example

At present, the number of motor vehicles in our country is increasing exponentially, and solving the problem of "parking difficulty" has gradually become an important link in urban traffic management, and the optimization of the spatial layout of urban parking lots is the core key to further improve the problem of "parking difficulty" in our country. Therefore, this paper takes the layout of Wanda outdoor parking lot in Panzhihua as an example. The minimum turning radius, the best Angle value and the width of parking channel are studied, and the optimization model and nonlinear mathematical optimization model of parking space arrangement are constructed. Based on LINGO software program design, the algorithm of optimal parking space arrangement is discussed, and the parking space planning and design scheme with the maximum space utilization rate under different restrictions is obtained. The research shows that: The optimization model of parking space arrangement and nonlinear mathematical programming model are adopted to optimize the regular area. The parking speed and utilization rate of parking space are significantly improved by using the parking mode with a tilt of 45 degrees and the scheme design of non-motor parking space layout, which can effectively increase the number of parking Spaces by 30 and non-motor parking Spaces by 80. The relevant research provides reference for the scheme design of large parking lots.
