| 摘要： | The broader goals of the Reliability focus area within the second Strategic Highway Research Program (SHRP 2) are to address unexpected traffic congestion and improve travel time reliability. To this end, SHRP 2 research projects have brought forward numerous technical measures and policies for further consideration and development. In parallel with these projects, the L04 project, Incorporating Reliability Performance Measures into Operations and Planning Modeling Tools, is aimed at improving planning and operations models to create suitable tools for the evaluation of projects and policies that are expected to improve reliability. The L04 project addressed the need for a comprehensive framework and conceptually coherent set of methodologies to (1) better characterize reliability, and the manner in which the various sources of variability operate individually and in interaction with each other in determining overall reliability performance of a network; (2) assess the impact of reliability on users and the system; and (3) determine the effectiveness and value of proposed counter measures. In doing so, this project has closed an important gap in the underlying conceptual foundations of travel modeling and traffic simulation, and provided practical means of generating realistic reliability measures using network simulation models in a variety of application contexts. |
