基于CUBE的公共自行车衔接换乘影响研究

A study on Connection and transfer effect of the public bicycle based on CUBE

为改善城市公交预测模型的预测效果,提高其对交通方案评价的可靠性,分析了CUBE软件PT模块的运行机理,考虑西安市公共自行车的大规模使用和城市交通模型PT模块中未包含公共自行车出行方式的不足,在原有的PT模块基础上增加了公共自行车接驳和换乘模式,提出了一种包含公交、公共自行车、步行共三种出行方式的改进的公交预测模式。以西安市高新区BRT线路规划为例,对改进的公交预测模式进行了应用。改进前后的预测数据对比分析结果显示:添加公共自行车模块后,3条BRT线路连接小区的数量分别增加11个、12个、18个,与常规公交的换乘量分别增加7.5%、8.1%、9.3%,全天客运量分别增加9.2%、10.2%、13.6%,准确反应了公共自行车在改善公交接驳方面的作用。

To improve the prediction accuracy and reliability of urban public transport model,the operation mechanism of PT module in CUBE was analysed. Considering the massive use of public bicycle in XI＇AN and the deficiency of lack of public bicycle in PT module,public bicycle connection and transfer mode was added in PT module and an improved transit prediction mode containing transit,public bicycle and walking was put forward. The improved prediction mode was applied in XI＇AN High- tech zone BRT program and the results of the original and the improves models shows that the number of communities connected by three BRT lines increase 11,12,18; the transfer volumes between three BRT lines and buses increase by 7. 5%,8. 1%,9. 3%,passenger traffic volumes in one day increase by 9. 2%,10. 2%,13. 6%,which reflects the function of public bicycle in transit connection.
