STUDY TECHNIQUES FOR PLANNING FREEWAY SURVEILLANCE AND CONTROL
FOUR STUDY TECHNIQUES, FOUND TO BE QUITE USEFUL IN PLANNING THE PEAK PERIOD FREEWAY SURVEILLANCE AND CONTROL ACTIVITIES ON THE GULF FREEWAY IN HOUSTON, ARE PRESENTED' /A/ ENTRANCE RAMP ORIGIN-DESTINATION STUDIES, /B/ INPUT- OUTPUT STUDIES OF CLOSED FREEWAY SUBSYSTEMS, /C/ AERIAL PHOTOGRAPHY, AND /D/ INPUT-OUTPUT STUDIES OF CRITICAL INTERSECTIONS IN THE STUDY AREA. DATA FROM THESE STUDIES CAN BE USED TO PLAN PEAK PERIOD RAMP CONTROLS BECAUSE THE DEMAND AND CAPACITY CAN BE ESTIMATED AT EACH BOTTLENECK /BOTH ON THE FREEWAY AND ON THE FRONTAGE ROADS AND STREETS/ AND TO PLAN ARTERIAL STREET CONTROLS TO PROVIDE FOR DIVERTED TRAFFIC BECAUSE THE TRAVEL PATTERNS OF FREEWAY INTERCHANGE TRAFFIC CAN BE DETERMINED. THE DURATION AND SEVERITY OF CONTROL AT EACH RAMP WHICH ARE REQUIRED TO PREVENT CONGESTION CAN BE ESTIMATED. THE DATA ARE ALSO USEFUL IN BEFORE-AND-AFTER COMPARISONS. /AUTHOR/
