在大量调查数据的基础上,通过停车特征参数的分析,提出了影响停车需求的多个因素。对其中的几个主要因素进行主成分分析,剔除权重最小的因素,建立了停车需求与剩余因素之间的预测模型。 Based on a large number of survey data, several factors influencing parking demand are proposed through the analysis of parking feature parameters. Principal component analysis is carried out for several of the major factors, the least weighting factors are removed, and the forecasting model between parking demand and residual factors is established.
