| 摘要: |
| 公交专用道虽能有效地保障公交优先,但其对公交乘客产生的巨大吸引力,能够引发公交网络中局部区域的客流转移,对公交运营造成影响. 为准确获取该变化的具体范围及程度,结合公交出行特征,在改进后的公交换乘网络基础上,提出一种重叠社团结构检测算法以确定出专用道的可影响范围,并进一步利用改进后的公交站点网络,利用Djkstra算法提出影响模型以计算具体影响程度. 最后根据实际调研数据验证了方法的合理性. 研究表明:公交网络中线路间的相互联系是专用道影响的基础,而换乘条件是限制其影响的重要因素. 与专用道站点之间具有至多一次换乘关系的站点集构成了专用道的影响范围,乘车资源及环境则决定其影响程度. 研究结果,可对既有专用道进行评估及其进一步施划. |

| Abstract: |
| Although the bus lanes could guarantee public transport priority effectively, their great attraction to bus passengers can lead to the transfer of passenger flow in local area of bus network, and has an impact on bus operation. In order to accurately obtain the specific scope and extent of this change, this research put forward an overlapping community structure detection algorithm based on the improved bus transfer network, and used the improved bus station network and Djkstra algorithm to propose an impact model to calculate the specific impact degree. Finally, the rationality of the method was verified in accordance with the actual survey data. Results show that the interconnection among bus lines in the public transport network is the basis of the influence of the bus lanes, and the transfer conditions are the important factors limiting its influence. The set of stations with a maximum of one transfer relationship with the bus lane stations constitutes the scope of the impact of the bus lane, and the impact degree is determined by the resources and environment of the bus. The results can be used to evaluate the existing bus lanes or to further planning. |
