• Abstract:
  Priority entry ramps have been operational in Dallas and Houston for approximately five years. An evaluation of these installations indicated three of the four sites exhibited positive benefits in terms of delay savings to high-occupancy vehicle patrons authorized to use the priority entry ramp. Significant cost-effectiveness was found to be associated with priority entry bypassing ramp metering signalization. Violations of priority entry ramps decreased as the relationship between non-priority vehicle delay and priority vehicle demand increased. A benefit-cost methodology for assessing priority entry ramp effectiveness was formulated and recommended guidelines for implementation of priority entry ramps given.
