基于公交可达性的公交方式选择模型研究

Mode Split Model Study Based on Bus Accessibility

交通方式选择是公交出行需求预测的关键内容之一。文章在公交方式选择效用函数中加入起点和终点交通小区的交通可达性(考虑公交站点到达时间、站台数量、线路条数、发车频率等),对Logit模型进行改进,并用海口市居民出行调查数据对改进模型进行验证,结果表明改进模型划分结果更接近真实值。

Transportation mode split was one of the key elements of bus travel demand forecasting. The bus transportation ac- cessibility of the starting and ending traffic zone were added to the bus choice utility function to improve the Logit model con- sidering the time to the bus station,the number of bus stops,the number of lines,departure frequency,etc. Haikou resi- dents travel survey data were used to verify the improved model. The results showed that the improved model mode split was closer to the true value.
