Choices among alternative transit capital investments are often complex and politically controversial. There is renewed interest
in the use of performance indicators to assist in making rational and defensible choices for the investment of public funds.
To improve the evaluation of rail and bus performance and provide more useful information for transit investment decision-makers,
it is important to use performance indicators that fairly and efficiently compare different transit modes. This paper proposes
a set of inter-modal performance indicators in which service input, service output, and service consumption are measured by
total cost, revenue capacity miles/hours, and unlinked passenger trips/miles respectively based on economic principles and
evaluation objectives. The proposed improvements involve the inclusion of capital as well as operating costs in such comparisons,
and the recognition of the widely varying capacities of transit vehicles for seated and standing passengers. Two California
cases, the Los Angeles – Long Beach Corridor and the Market/Judah Corridor in San Francisco, are used for testing their usefulness
in the evaluation of the efficiency and effectiveness of rail and bus services. The results show substantial differences between
performance indicators in current use and those proposed in this study. The enhanced inter-modal performance indicators are
more appropriate for comparing the efficiency and effectiveness of different modes or a combination of transit modes at the
corridor and system levels where most major investment decisions are made.

针对既有线施工风险事故高发,进度难以顺利开展的现状问题,提出一种基于SD的既有线施工多目标决策分析方法。在实践基础上对既有线施工关键问题安全和进度进行识别,并构建多目标管理系统结构框图;在此基础上确定模型边界和子系统,通过劳动力数量、操作水平和返工率等要素深入反映系统目标之间的相互影响关系并构建因果关系图;结合案例进行模型仿真,对不同行为模式和不同天窗兑现率下的系统变化趋势进行对比分析,提出系统满意解和不同系统目标下的优化策略,结果表明,天窗兑现率对既有线施工违章和风险水平影响较大,为既有线施工安全管理提供了政策支持和参考。 相似文献

基于地铁自动售检票系统连续一周的数据,从多粒度、多层次、多角度对比分析了北京与伦敦地铁乘客的出行规律。结果显示:北京与伦敦地铁乘客的出行频次分布相似,但伦敦地铁的高频出行乘客更多,而北京地铁的低频出行乘客更多;伦敦地铁的总体换乘比例略低于北京,更便捷,且伦敦的短距离出行比例远高于北京;北京地铁周末的通勤出行更多,而伦敦市民从周五至周日的夜晚出行更多。地铁乘客的出现规律不仅与城市结构,居民的工作生活状态有关,对城市轨道交通的网络结构及运营管理也有重要的参考价值。 相似文献
