Abstract

The majority of the fuzzy controllers in the literature depend on simple logic that particularly depends on raw data of a single detector. Their input variables are usually simple estimates of traffic measures such as flow, speed or occupancy, estimated from such single detector readings. A room for improvement is sought in this paper by developing a fuzzy logic model (FLM) that could be integrated with smarter "processing" tools to estimate several traffic measures from multiple detectors on each approach. The estimates obtained from this processing tool are integrated as input knowledge into the FLM. The mathematical formulation of these traffic measures is presented. The fuzzy logic structure is addressed in details. A simulation model is devised to test the effectiveness of the FLM. The results are presented and discussed in details.
