| Abstract: | This research investigated the delays incurred by motorists on two-way freeway frontage roads at intersections with entry and exit ramps. These delays were compared with the delays on one-way frontage roads. Four field studies were conducted in medium-sized Texas towns. Studies were conducted on both lanes of a two-way frontage road at an intersection with an exit ramp, and on a lane of a two-way frontage road opposing the traffic turning into an entry ramp. One study gathered data where an exit ramp intersected two moving lanes of a one-way frontage road. Signs required the frontage road traffic to yield to the ramp traffic at all of the study sites. Two types of delay models were derived from the study data. First, delay was regressed against frontage road and ramp volumes to form models. In addition, delay models based on the Poisson arrival process and queueing theory were formulated. The research found that for similar volumes, motorists on two-way frontage roads were delayed at ramp intersections more than motorists on one-way frontage roads. The average delay per vehicle was significant only for higher frontage road volumes, even on two-way frontage roads. |
