提出了一个大型城市路网中需求响应型公交系统运营成本的连续统近似模型。模型的应用揭示了DRT系统的需求和特性如何影响成本的主要组成部分：车队、车辆小时数和车辆行驶里程。用经验数据验证了这种关系，结果表明，新泽西州的辅助医疗系统的运营成本是一个准确的近似。此外，我们开发了一种系统的方法来评估DRTS的政策实施的效率。最后，确定了协调出租车可以作为降低成本策略的情况。
This paper presents a continuum approximation model for the operating cost of demand responsive transit (DRT) systems in large urban networks. Applications of the proposed model shed light on ways demand and characteristics of the DRT system affect major components of cost: fleet, vehicle hours, and vehicle miles traveled. Verifying the relationship with empirical data, results show an accurate approximation of the operating cost for the paratransit system in New Jersey. Furthermore, we develop a systematic approach for evaluating the efficiency of policy implementations for DRTs. Finally, the circumstances where coordinated taxis could be a cost reduction strategy are identified.
