RESULTS OF THE ON-LINE IMPLEMENTATION AND TESTING OF A FUZZY LOGIC RAMP METERING ALGORITHM

A fuzzy logic ramp metering algorithm was implemented on 126 ramps in the greater Seattle area. Two multiple-ramp study sites were evaluated by comparing the fuzzy logic controller (FLC) to the other ramp metering algorithm in operation at that site over a 4 month period. On the first study site, the FLC metered days had reduced mainline occupancies, and increased throughput volume compared to the days metered with the local algorithm. At the second study site, the FLC metered days had similar mainline occupancies, significantly reduced queues, and similar throughput volume compared to the days metered with the bottleneck algorithm
