A closed-circuit television system now exists for a six-mile section of the Gulf Freeway in Houston, Texas. It permits complete surveillance of the traffic flow as well as the expedient handling of accidents or stalled vehicles on the freeway. The television monitors are housed in the central control center. Data on the operation of the Gulf Freeway, collected daily since September 15, 1965, have provided an excellent basis for evaluating the effect of the ramp control. The data show significant improvements in operation as compared to the before period when no ramp controls were in effect. In addition to research studies of the manual control system, developmental work was initiated on an automatic ramp control device which could replace the manual ramp control.
