RAMP METERING ON THE BLACK CANYON FREEWAY

The problem of recurrent congestion and its partial solution is discussed, experience in New York, Texas and California are reviewed, and details are given of freeway control in Phoenix. Studies revealed that ramp metering would be beneficial for southbound traffic during the morning peak period in certain southbound on-ramps. Details are outlined of the facility as well as of city arterials. Observations made after initiation of the ramp metering system indicate that east-west travel times on city arterials decreased and peak hour speeds on the freeway generally increased. The number of peak-hour accidents has also been reduced.
