摘要: |
This guidebook presents a framework and cost-effective methods to estimate, predict, measure, and report travel time, delay, and reliability performance data. The framework is applicable to highway vehicular traffic and also can be used for highway-carried public transit and freight vehicles. The guidebook presents and assesses performance measures currently believed to be most appropriate for estimating and reporting travel time, delay, and reliability from a perspective that system users and decision makers will find most understandable and relevant to their experience and information needs. This guidebook also presents various data collection methods, analysis approaches, and applications that most effectively support transportation planning and decision making for capital and operational investments and for quality of service monitoring and evaluation. Methods are presented in a manner to be useful for application in a range of settings and complexity, but are not intended to support real-time applications of travel-time data such as Traveler Information programs. |
