Can ramp signals save the commuter time and/or money?
Over the years, every ramp signaling project in the United States has been subjected to exhaustive “before and after” tests using electronic counters, in-pavement sensors, computer studies, and even photography. Systems with ramp signals in place show that average speeds on the mainline freeways do increase, and sometimes rather substantially. With the future implementation of ramp signals, it is estimated that there will be: • Reduction in time spent in traffic due to the easing of recurring and non-recurring congestion • Savings in gas due to less stop and go traffic on the mainline • Savings due to a proven record of reduced crashes • An increase in travel time reliability due to lower flow and congestion which will allow a more consistent commute time during ramp signal operation.
