Freeway management handbook

This handbook is an update of the 1983 edition and reflects the tremendous developments in computing and communications technology. It also reflects the importance of "Integrated" Transportation Management Systems and the development of the concept of Intelligent Transportation Systems (ITS). The handbook development began with a survey of current practice, including site visits and interviews, of ten Freeway Management Systems throughout the country. It was developed under the advice of a panel of freeway management practitioners. The 1997 edition is organized in modular fashion with each module addressing a particular aspect or technology of the freeway management task. The modules are stand-alone treatments of particular areas of freeway management but are cross-referenced to reflect their interdependence. Each module is organized as follows: INTRODUCTION - Including Module Objective and Scope; DECISION PROCESS - Partners and Consensus Building, Establishing Goals and Objectives, Performance Criteria, Functional Requirements, System Architectures, Identification and Screening of Technologies, and Implementation; TECHNIQUES AND TECHNOLOGIES - Applications specific to the module; LESSONS LEARNED - Experiences and observations from operating systems; and REFERENCES - Comprehensive list of references used in module preparation. Specific modules are as follows: Introduction and Executive Summary; (1) Freeway Management Concepts; (2) Decision Process; (3) Surveillance; (4) Lane Control; (5) Ramp Control; (6) HOV Concepts; (7) Information Dissemination; (8) Incident Management; (9) Communications; (10) Control Centers; and (11) Economic Analysis.
