HARBOR FREEWAY RAMP CLOSURE

THE EFFECT IS INVESTIGATED OF RAMP CLOSURE ON THE TRAFFIC OPERATIONS OF A FREEWAY AND AN ADJACENT ARTERIAL STREET. TRAFFIC OPERATION ON THE FREEWAY DURING PEAK HOURS EXPERIENCED CONGESTION DUE TO ADDITIONAL DEMAND AND POOR GEOMETRIC DESIGN OF THE FIGUEROA ON-RAMP. CLOSURE OF THIS RAMP RESULTED IN IMPROVEMENT IN THE TRAFFIC FLOW ON THE FREEWAY WITHOUT SERIOUSLY AFFECTING THE OPERATION OF THE ARTERIAL. IT WAS CONCLUDED THAT WHERE UNUSED CAPACITY IS AVAILABLE ON ALTERNATE ROUTES RAMP CLOSURE CAN RESULT IN IMPROVEMENT TO FREEWAY OPERATION AND AN APPRECIABLE TIME- SAVING TO THE COMBINED SYSTEM. /BPR/
