| 摘要： | The Guide to Incorporating Reliability Performance Measures into the Transportation Planning and Programming Processes is intended to be a high-level reference document for transportation planners, operators, and system managers. The reliability of the transportation system refers to the uncertainty or variability that system users experience in the time it takes to travel from one place to anotherfrom home to work, from producer to consumer, and from any location to another. This guide will help planning, programming, and operations managers to apply the concept of travel time reliability to balance investment in programs and projects. This guide has been developed at a time of significant changes in the transportation planning and programming process. The Moving Ahead for Progress in the 21st Century Act (MAP-21) transportation bill requires transportation agencies to use a performance-based approach to planning and programming. Reliability and congestion reduction are explicit goals of the bill, though the specifics of how agencies are expected to implement these requirements remain to be seen. At the same time, significant research on data and tools to evaluate reliability is helping agencies better understand and predict the variability of travel time. The purpose of this guide is to help agencies wherever they may be in the process of using reliability performance measurement to (1) understand and communicate reliability; (2) identify the tools and methods to help them track transportation system reliability; (3) begin to incorporate reliability into their existing analysis tools; and (4) identify emerging analysis tools that will better help them evaluate reliability and make program and project investment choices that address the reliability of the system. |
