提出了一种公交线路运营中间规划的优化框架。服务模式在不同的运营期，其中包括短转弯策略（全长和短转弯线）和可变的车辆大小，被认为是。优化的变量为：运营折返的位置、车辆大小、频率（按运营期），以及在公交车定期到达的情况下，全长和短折返线路的相对偏移（按运营期）和票价。目标函数是净效益，其表示为用户因较低的平均等待时间而获得的效益减去票价不包括的运营商成本。给出了求解该问题的数值方法。它的应用程序的径向走廊条件的情况下代表显示的服务模式的影响和用户和运营商的成本之间的权衡，从不同的设计标准，根据附加到两个球员的操作期间。(C)1998 Elsevier Science Ltd.
An optimization framework for intermediate-level planning of bus operations on a given corridor is presented. Service patterns over different operation periods, which include short-turn strategies (full-length and short-turn line) and variable vehicle size, are considered. Variables optimized are: positions where turnbacks are operated, vehicle size, frequencies (by operation period) and, where bus arrivals are regular, relative offset (by operation period) of full-length and short-turn line, and fare. The objective function is the net benefit represented by benefits that accrue to the users for lower average waiting times minus operator's costs not covered by fares. A numerical procedure to solve the problem is provided. An application of it to a case representative of radial corridor conditions shows the effects on service patterns and the trade-offs over operation periods between users' and operator's costs, stemming from different design criteria according to the weights attached to the two players.
