A Novel Intelligent Traffic Light Control Scheme

Abstract

Traffic congestion has become a major problem in today's society. It may cause a great waste of material and human casualties. We think the fixed-time-state traffic light control scheme is one important reason. An intelligent traffic light control scheme is necessary in order to give a solution to this problem. The paper proposes a model to describe a road cross. In terms of dynamic and real-time traffic information, weights of all the serial lanes are dynamically computed, so as to automatically manage the current status and duration of traffic lights. The proposed novel control scheme consider traffic situations of both upstream lanes and downstream lanes, in order to reduce average vehicle waiting time at a road cross. The paper further performs simulations for the proposed scheme and gives detailed analysis on parameters which have great influence on scheme performance. Results show that the proposed scheme outperforms the fixed-time-state traffic light control scheme on average vehicle waiting time.

Design Approach for Adaptive Traffic Light  Control System Based on Radio Propagation Model in VANET

“…[1,3].In this wireless sensor network is used to collect real time various traffic condition. Large number of sensors are placed along each end of a road so as to count arriving vehicles.…”

“…Higher traffic in the city generates severe problems like accidents, congestion, pollution etc. To handle all these problems and also to make traffic free flow on the intersections some intelligent traffic must be designed .Making changes in the urban area infrastructure is a expensive and usually not possible, researchers often agree in that instead of changing infrastructure ,some new scheduling of traffic lights should be introduced which will helpful to reduce these problems by improving the flow of vehicles through the intersection or lanes in the cities [3].Vehicles in the traffic are mobile nodes i.e. they are moving from one place to another place [4].Vehicular ad hoc networks (VANET) are one of the best tools for this purpose.…”

Implementation of Dynamic Fuzzy Logic Control of Traffic Light with Accident Detection and Action System using iTraffic Simulation

“…This automated system is one of the essential reasons for the traffic congestion, and it does not provide an optimal control for fluctuating traffic volumes. That may cause a significant waste of material and human casualties [2]. To alleviate this problem, many traffic control systems have been developed with limited success.…”

Enhancing Traffic Flow Using Vehicle Dashboard Traffic Lights with V2I Networks

“…In Cheng Hu's work [5], a road cross is described in terms of lanes and directions, and a set of all possible states that can occur on the intersection is defined -each state consists of two lanes on which vehicles can get along in the intersection safely. The system computes the weight of each state based on the number of vehicles -gathered with the aid of sensors installed on the side of the road -flowing on the lanes of the corresponding states, and then gives green lights for vehicles on the combined lanes' state that has the highest weight.…”
