公共交通作为通勤者的主要出行方式，在缓解城市交通网络拥挤方面发挥着重要作用。开发了一个模型，考虑异构需求，优化所有停止，短转，快速公交服务和相关的频率，具有成本效益的操作。对于给定站点和起讫点需求的公交线路，通过考虑一组约束条件来优化目标总成本函数，这些约束条件确保频率守恒和受可操作车队规模的足够容量。最后，以某轨道交通线路为例，验证了模型的适用性和有效性。结果表明，优化的综合服务模式和相关的服务频率显着降低总成本。
As a major mode choice of commuters, public transit plays an important role in relieving congestion on urban transportation networks. A model is developed for cost-efficient operation that optimizes all-stop, short-turn, and express transit services and the associated frequencies by considering heterogeneous demand. For a transit line with given stations and origin–destination demand, the objective total cost function is optimized by considering a set of constraints that ensure frequency conservation and sufficient capacity subject to operable fleet size. A numerical example is designed that is based on a real-world rail transit line to demonstrate the applicability and effectiveness of the developed model. Results show that optimized integrated service patterns and associated service frequencies significantly reduce total cost.
