Abstract: In response to the insufficient energy efficiency in the joint operation mode of conventional bus and demand responsive transit, this paper proposes an energy-saving oriented transit scheduling decision and ecological speed collaborative optimization method by introducing eco-driving technology. With the purpose of minimizing total operational cost and the penalty cost caused by asynchronous schedules, a mixed integer optimization model was developed with the constraints of passenger travel time window preferences and schedule coordination. Feasible range of conventional bus eco-speed are derived for four signal phase and timing scenarios, and the conventional bus eco-speed, actual arriving time, and demand responsive bus fleet size, route, schedule, and eco-speed are synthetically optimized. A three-stage mixed heuristic algorithm is designed based on the model properties. To verify the effectiveness of the proposed method, a case study is conducted in the Chongqing University town area, simulating the actual scenario of joint operation of conventional and demand-responsive buses. The results show that compared with traditional scheduling method, the proposed method can reduce the total system cost by more than 16.2%. Through adjusting eco-speed, the idle waiting at signalized intersection is avoided, and the arrival punctuality and the goal of energy saving are taken into account. In addition, this method also improves the turnover rate of demand responsive-bus, then reduces the fleet size, increases the timetable synchronization by 81%, fully meeting the passengers' time window preference and hybrid scheduling requirement.

摘要: 针对常规公交和需求响应公交联合运营模式下存在的同步性差和能耗高的问题,本文通过引入生态驾驶技术,提出一种低能耗导向的公交混合调度决策和生态车速协同优化方法。以最小化公交运营成本和时刻表不同步所产生的惩罚成本为目标,考虑乘客出行时间窗偏好和时刻表协同等关键约束条件,构建混合整数优化模型,推导4种信号相位配时场景下的公交生态车速可行区间,协同优化常规公交的生态车速、实际到站时间,以及需求响应公交车队规模、路径、时刻表和生态车速,并根据模型性质设计三阶段 混合启发式算法。为验证所提模型和算法的有效性,选取重庆大学城片区开展案例分析,模拟常规公交和需求响应公交联合运营的实际场景。结果表明,与传统混合调度方法相比,本文提出的方法能够降低系统总成本约16.2%。通过调整行驶车速,避免常规公交在信控交叉口的怠速等待,兼顾到站准时和能耗节约目标。此外,该方法还提升了需求响应公交单车周转率,减少了车队规模,接驳站点处时刻表同步性提升81%,充分满足乘客出行时间窗需求和混合调度要求。
