A Fuzzy Signal Controller for Isolated Intersections
نویسندگان
چکیده
Fuzzy reasoning has become an important intelligent control method for traffic operation. This paper proposes a new fuzzy control system for signal control of an isolated intersection. This new fuzzy signal control system (FSCS) contains fuzzy phase selector and fuzzy green phase extender functions, which located in different levels of this multilevel signal control system. The phase selector is working on the phasing, while the green extender belongs to the green extension level of this multi-level signal control system. The phase selector function determines the next green phase and green extender controller function makes the decision whether to extend or terminate the current green phase. Simulation is used to evaluate the performance of the proposed FSCS system. The FSCS system is compared with pre timed control system and shows significant improvement over pre timed control strategy. © 2009 World Academic Press, UK. All rights reserved.

This paper presents two optimal approaches of two-stage fuzzy controller for traffic signals at isolated intersections. Firstly, in the light that traffic status variables in two-stage controller leads to the inefficiency of traffic status weakening under low traffic flow, a two-stage combination fuzzy controller is designed from the perspective of structural optimization; this controller intro...

Intelligent control in road traffic intersections can be an alternative to a conventional control where duration of each signal phase is predetermined. In this article fuzzy logic approach for traffic signals control is considered and applied for an isolated intersection. Number of vehicles in each lane is measured with loop detectors. At the end of each phase these numbers are used as inputs t...

متن کاملSelf-Organizing Traffic Control via Fuzzy Logic
We present an approach to self-organizing traffic signal control based on a fully distributed system of cooperative local controllers. The signal timing parameters at each intersection are adjusted by a local controller as functions of the local traffic condition and of the signal timing parameters at adjacent intersections. Each local controller uses a set of fuzzy decision rules to adjust the...
