FREEWAY RAMP CONTROL SYSTEM

A SUMMARY OF THE DEVELOPMENT OF FREEWAY RAMP CONTROL SYSTEMS IS PRESENTED IN THIS REPORT, WHICH IS THE LAST OF A SERIES OF TWENTY-SIX (26) REPORTS ON VARIOUS ASPECTS OF FREEWAY OPERATION, TRAFFIC SURVEILLANCE, AND CONTROL. THE THEME OF THIS REPORT IS THAT FREEWAY RAMP CONTROL SYSTEMS HAVE BEEN ADEQUATELY TESTED AND EVALUATED AND PROVEN TO BE EFFECTIVE IN IMPROVING FREEWAY OPERATIONS. THE DESIGN AND OPERATION OF THE CONTROL SYSTEMS WILL CONTINUE TO BE STUDIED AND IMPROVED, BUT CONSIDERABLE BENEFITS CAN BE DERIVED BY THE FREEWAY MOTORIST FROM THE IMMEDIATE IMPLEMENTATION OF THESE SYSTEMS ON FREEWAYS NOW EXPERIENCING TRAFFIC CONGESTION. THE SUGGESTED WARRANTS, DESIGNS, AND OPERATIONAL CONSIDERATIONS PRESENTED IN THIS REPORT ARE BASED ON THREE YEARS OF OPERATION OF THE GULF FREEWAY SURVEILLANCE AND CONTROL SYSTEM AND THE INFORMATION DERIVED FROM CONFERENCES WITH OTHER CONTROL PROJECTS IN THE UNITED STATES. THIS MATERIAL AND THE REPORTS REFERENCED IN THE PAGES PROVIDE THE NECESSARY FRAMEWORK ON WHICH A CITY OR STATE TRANSPORTATION DEPARTMENT CAN PLAN AND DEVELOP AN URBAN FREEWAY CONTROL SYSTEM. /AUTHOR/
