摘要
本文阐述了区域客流预测模型与市域模型差异,将城市引力模型引入到区域客运交通预测模型中,利用城市引力模型建立城际间客流生成及分布预测,并采用有序多分类logistic模型开展区域客流方式划分预测。以粤港澳大湾区区域客流分析为例,利用多源大数据对区域模型参数进行标定,开展相关趋势分析和应用研究。结论表明基于城市引力的区域客运交通模型具有较好的操作性和适用性。

Abstract: The difference between regional passenger transportation model and urban traffic model is elaborated in this paper, and the city gravity is introduced into the regional passenger transportation model, which establishs the inter-city passenger flow generation and distribution, and constructs mode split model using multi-class logistic model. Taking the analysis of Guangdong, Hong Kong and Macau Bay Area as an example, the multi-source big data is used to calibrate the regional model parameters, predict the changes of passenger flow and mode in the Bay Area. It can be concluded that the regional passenger transportation model based on city gravity has good operability and applicability.
Keywords: city gravity; regional transportation model; Guangdong, Hong Kong and Macau Bay Area; big data
