Optimal Traffic Light Control for a Single Intersection

An Optimal Dynamic Control Method for an Isolated Intersection Using Fuzzy Systems

Traffic flow systems are nonlinear and uncertain, so it is very difficult to find their optimal points. In traditional traffic control systems, the traffic lights of crossings change in a fixed time period that is not optimal. On the other hand, most proposed systems are sufficiently capable of coping with the uncertainties of traffic flow. To solve this problem, there is a need to develop expe...

Optimal traffic light control for a single intersection: Addendum

Optimal Signal Control in Urban Road Networks with High Priority Congested Centers

Keeping the density of traffic flow and air pollution in an acceptable level and developing a good capacity for transit in the high priority areas of the city, is really a big deal in large and crowded cities. To address this problem, a new method of intersection signal optimization is presented in this paper. Based on network fundamental diagrams, an Internal–External Traffic Metering Strategy...

Optimal Feasible Green Light Assignment to a Traffic Intersection using Intersection Graph

A feasible green light assignment is an assignment of time period to each traffic stream so that only compatible traffic streams are allowed to recieve overlapping time period. In case of an intersection, it is almost always possible to find several feasible green light assignments. We usually have some goal such as to minimise the total waiting time, to maximise the volume of flow etc. , to be...

Fuzzy Control of Traffic Signals Accompanying Pedestrian Crossings

In this paper, a fuzzy logic control system was constructed for controlling the green time length for a real single intersection with multiple lanes, turns, and two pedestrian crossings. Control of pedestrian crossingd was achieved by assigning pedestrian crossingd into related light phases, which were controlled by a fuzzy logic controller. An evolutionary algorithm was employed to generate th...
