FREEWAY ON-RAMP TRAFFIC-RESPONSIVE CONTROL METHODOLOGY

The report describes the development of a freeway on-ramp traffic-responsive real-time control methodology for alleviating both recurrent and nonrecurrent congestion on urban freeways. The control logic is synthesized into two levels of response; strategic control level and tactical control level. An efficient upper-bounding linear program was also developed and tested as part of the computer implementation of the control methodology. Immediate future needs are also presented and discussed.
