针对当前县域旅游巴士接驳服务存在的路径规划不合理、动态调度能力不足等突出问题，引入景区空间离散性、出游时效敏感性及运力资源有限性等特征约束，构建一种考虑客流分配的县域旅游巴士接驳路径规划模型。该模型以游客总乘车时长与旅游巴士总行程时长最小化为优化目标，并采用GUROBI优化器进行求解。随后，基于福建省平潭县的数据进行案例分析，通过权重系数实验探究目标间的协同优化效果，并开展运力利用率压力测试。结果表明：相较于点对点直达的基准方案，优化方案的游客总乘车时长仅增加0.6%，而车辆总行程时长降低23.2%；在运力缩减12.5%的极端条件下，优化方案仅以游客总乘车时长增长4%、车辆总行程时长增长8%的代价，实现了旅游巴士89.3%的峰值运力利用率，证明了模型在县域旅游场景下的可行性与鲁棒性。研究表明，采用该旅游巴士接驳路径规划模型，能高效配置县域旅游接驳资源，在保证游客出游体验的同时，兼顾旅游巴士运营成本的控制。

To address prominent issues in current county tourism shuttle bus services, such as inefficient route planning and insufficient dynamic scheduling, a shuttle bus route planning model considering passenger flow allocation was developed. This model explicitly incorporates key constraints, including the spatial dispersion of attractions, tourist sensitivity to travel time, and limited fleet resources. The optimization objectives were defined as minimizing total passenger travel time and total vehicle operating time. Solving was performed using the GUROBI optimizer. Then, a case study based on data from Pingtan County, Fujian Province, demonstrated the model′s effectiveness. Experiments varying the weight coefficients investigated the collaborative optimization between objectives. Pressure tests on fleet utilization were also conducted. Results indicated that, compared to a point-to-point direct shuttle baseline solution, the optimized solution increased total passenger travel time by only 0.6%, while significantly reducing total bus operating time by 23.2%. Under the extreme condition of a 12.5% fleet reduction compared with regular scenarios, the solution achieved a high peak fleet utilization rate of 89.3%. This performance came at a modest cost: a 4% increase in total passenger travel time and an 8% increase in total bus operating time, demonstrating the model′s feasibility and robustness in county tourism contexts. The study shows that adopting this shuttle bus route planning model enables efficient allocation of county tourism transfer resources. It effectively balances controlling shuttle bus operating costs against ensuring a satisfactory travel experience for tourists.
