摘要： 定制公交既有研究主要集中于线路的定制规划和需求的定制响应，然而提升运行效率同样值 得关注。车路协同技术在检测精度和传输实时性方面的优势有助于提升定制公交运行效率，并可为 定制公交的运行效果评价提供数据来源。首先，基于互联网位置大数据明确定制公交线路规划的步 骤并进行精准选线，同时基于车路协同技术提出定制公交信号优先系统设计方法。然后，以车路协 同环境下产生的大量交互数据为基础对定制公交运行效果进行评价，从交通需求承载水平、通勤效 率提升水平、乘客出行体验水平以及车路协同服务水平4 个评价维度入手，确定14 个评价指标，并 利用层次分析法构建定制公交运行效果的评价方案。最后对长沙市梅溪湖—高新区通勤定制公交进 行实例评价，验证了评价方案的合理性和可参考性。

Abstract： The existing literature on customized bus services mainly concentrated on route planning and tailored responses to specific demands. Nevertheless, enhancing the travel efficiency of customized buses is equally deserving of attention. The advantages of Cellular Vehicle-to-Everything (C-V2X) in detection accuracy and real-time transmission are beneficial for improving the travel efficiency of customized buses, and can provide data sources for evaluating the operation performance of customized buses. Firstly, based on the Internet positioning data, the steps for planning customized bus routes are clearly defined, and a precise route selection philosophy is established. Meanwhile, a methodology for the signal priority system of customized buses is proposed based on C-V2X. Then, with the large amount of interaction data generated in a -V2X environment, the operation performance of customized buses is evaluated. The evaluation framework includes four evaluation dimensions, namely the level of travel demand carrying capacity, the level of improvement in commuting efficiency, the level of passenger travel experience, and the level of C-V2X service, and 14 detailed evaluation indicators are determined. Then the Analytical Hierarchy Process (AHP) is utilized to develop an evaluation scheme for performance evaluations. Finally, the example of customized commuting bus line from Meixi Lake to High-Tech Industrial Zone of Changsha is analyzed, and the rationality and applicability of the evaluation scheme were verified.
