| 摘要： | Ramp metering, as a major component of Advanced Transportation Management Systems (ATMSs) has been used in over 25 metropolitan areas in the United States. This paper documents the issues related to deployment to systemwide coordinated ramp metering systems. Guidelines are developed regarding implementation and operations of coordinated ramp metering systems based on a comprehensive literature review and agency surveys. A coordinated freeway ramp metering system is used to control a series of entrance ramps where the interdependency of entrance ramp operations is taken into consideration. The overall objective of a coordinated ramp metering system is to improve the efficiency and safety of freeway systems. A summary is provided regarding the current status of ramp metering, especially coordinated ramp metering system applications in the United States. The issues related to the various aspects of coordinated ramp metering systems and the procedures for implementing such systems are addressed. Guidelines are provided to achieve successful system implementation and operations. The features of the representative ramp metering algorithms are described. These algorithms represent the most advanced algorithms that have been successfully implemented and tested in the field. Guidelines are also developed to address the system performance evaluation process. Performance measures are recommended for conducting system evaluations. Results of various performance measures from previous studies are provided based on different types of ramp metering systems. This document contains information about the state-of-the-art technologies and developments in the area of coordinated ramp metering systems in the United States. The guidelines developed through this research can assist transportation agencies in dealing with various issues involved in the process of implementing coordinated freeway ramp metering systems. |
