There are different traffic light signal that controls motorists in Dubai City, one of the largest and busiest cities. Different light signals have been installed at designated pedestrian crossing paths on the main intersections. The three main signs are yellow, green and red lights, which every motorists plying on route in Dubai must be aware off. For example, the yellow light signal is an indication for pedestrians to slow down, while red releases all motorists on the go. Meanwhile, the green light allows motorist to go, and cross (Krane 188). However, violation to these traffic laws is subject to punitive actions, ranging from heavy fines, confiscation of the vehicle, or imprisonment to the traffic offenders. The main focus here would be about the design of these traffic light signals, and how they are coordinated with other road lighting parameter.
Dubai is currently shifting to the 3G technology that will coordinate all traffic light signals to a central point with the use of a wireless application. The Hi-tech system will give motorists enough time to brake without causing jitters on the roads. These lights are designed in such a manner that it takes 100 seconds, but only 3 seconds for lights to turn from red to amber, green to amber, respectively. The amber light flicks three twice, warning motorists to slow down. The Dubai traffic light system is coordinated with other radars and high sensitivity cameras that are able to monitor and record any motorists on the road (Krane 190). The amber light is the defining moment for motorists to either move or stop. In Dubai, motorists are allowed to move, but at a slower speed when light flicks amber, but would stop in case there are pedestrians crossing.
