Introduction of ramp meters in the Portland metropolitan area seemed to cause undue delay to transit buses. A Smart Ramp is introduced on a freeway on-ramp for use by transit and school buses, as well as high occupancy vehicles. These vehicles carry special tags, which are identified by on-site equipment to provide preemption in the bypass lane. The Smart Ramp operates during the morning and afternoon rush hours. This paper discusses the establishment and operation of the Smart Ramp. The ramp is monitored over a one-year period, when its usage is examined. Data on registered users, dwell times, and ramp's influence on encouraging carpools are gathered as part of research. User surveys are also conducted to determine ramp's acceptance. Including buses and high occupancy vehicles in the bypass lane encouraged some illegal use. Illegal usage and related enforcement issues are investigated. Overall, the ramp has been well accepted and served its intended purpose in encouraging carpooling and saving time (and costs) to travelers and the transit agency
