IMPROVING TRAFFIC FLOW AT INTERSECTION USING INTELLIGENT TRAFFIC MANAGEMENT SYSTEM

In this study, a proposed intelligent traffic management system is presented making use of the wireless sensor network for improving traffic flow.  By making use of the clustering algorithm, VANET environment is utilized for the proposed system. The components of the proposed system include sensor node hardware, vehicle detection system through magnetometer, and UDP protocol for communication between the nodes. The intersection control agent receives the information about the vehicles and by making use of its algorithm, it dynamically changes the traffic light timings. By making use of the greedy algorithm, the system can be enhanced to a wider area by connecting multiple intersections

Design and Development of Traffic Light and IR Camera Computer Network; a Tool for Infrastructural Planning and Revenue Generation

A traffic light is a device that gives the right of way to any road user. The device is design with three visible colours made up of the Red, Yellow and Green light. It is used to control the movement of vehicles entry or leaving a junction of a town or cities. The red colour light indicates danger or stop movement. The yellow (amber) colour indicates get ready to start or stop movement. The green light indicates crossing the intersection without danger. The infrared camera (IR) is a light emitting diode (LEDs) which can video an image in an extreme low or absence of light condition. The IR camera when installed on a traffic light will capture every vehicle image, colour and the registration number of every vehicle that is given the right of way across an intersection in various locations. The captured data can be stored in a software drive (SD-card) or the hard-disk of the computer. The traffic light and IR camera are interface with a computer network system for visible and data retrieving for further programming processing. This system when installed can be used for infrastructural planning and revenue generation for the Government. It can also be used to prevent road accident and monitor the incessant knapping of the citizen. It serves as a tool for moral discipline for road user when defaulters are persecuted and charge to pay fine. The system will eliminate manual system of controlling traffic and embarrassment caused when there is traffic jam. The system is cheap and easy to install

A Comprehensive Approach to WSN-Based ITS Applications: A Survey

In order to perform sensing tasks, most current Intelligent Transportation Systems (ITS) rely on expensive sensors, which offer only limited functionality. A more recent trend consists of using Wireless Sensor Networks (WSN) for such purpose, which reduces the required investment and enables the development of new collaborative and intelligent applications that further contribute to improve both driving safety and traffic efficiency. This paper surveys the application of WSNs to such ITS scenarios, tackling the main issues that may arise when developing these systems. The paper is divided into sections which address different matters including vehicle detection and classification as well as the selection of appropriate communication protocols, network architecture, topology and some important design parameters. In addition, in line with the multiplicity of different technologies that take part in ITS, it does not consider WSNs just as stand-alone systems, but also as key components of heterogeneous systems cooperating along with other technologies employed in vehicular scenarios
