DESIGN AND CONSTRUCTION OF 3-WAY TRAFFIC LIGHT
This project work is on design and construction of a 3-way traffic lighting system. A 3-way Traffic light is signaling device positioned at 3-way road intersections, pedestrian crossings and other locations to control competing flows of traffic. The road construction safety traffic light system is designed to replace a manual traffic control on a road construction sites. This device can replace one or both flaggers during the two lane closures on the event of a road construction. The road construction safety traffic light system is considered one of the best devices in work zone traffic flow control systems. The device is a portable traffic light unit which can be best utilized in controlling traffic flow in a road construction site for long term or short term lane closures and to control two-way traffic in a single lane. By implementing new technologies in automating traffic flow in road construction site could possibly eliminate the usage of a conventional flagman at all times. The road construction safety traffic light system is a practical solution to solve problems which contribute towards hazards at road construction site and to be inline with the road safety regulation which is taken into granted by the contractors. The automated portable traffic light system can reduce direct costs in man power utilization and increase safety for the road users and construction workers by eliminating the need for a human flagmen. This system is applicable for public and privately funded road construction projects that require overnight or 24-hour traffic control as well as in different weather conditions.
The purpose of this project work is to design and construction a 3-way traffic light device that can be used to control the flow of traffic at 3-way road intersection.
