Dubai traffic lights become wireless
The RTA has completed the final phase of replacing light signal control units using 3G technology
The Roads and Transport Authority (RTA) has announced that all of Dubai's traffic lights are now linked to a traffic control centre as part of the Smart City initiative.
The transformation has been carried out in phases, with the around 400 traffic control units have been successfully connected using 3G technology, isolated signals have been connected via wireless systems, and cable-connected signals have been switched to a wireless network.
Engineer Metha bin Adai, CEO of RTA's Traffic & Roads Agency, said: "The project is part of the Government's initiative to transform Dubai into a smart city. Cables used in linking light signals with the traffic control centre in Dubai have been replaced by wireless technology and isolated signals have been connected using the 3G technology.
"The new system has high usability and efficiency, and is easily maintained. It eliminates the lag in the timing of traffic signals, and is considered cost-efficient compared to the previous situation, which required an intensive infrastructure in terms of cables, telephone lines to run the service nearby each signal," said Bin Adai. "Thus, the project saves the cost of providing these lines along with the risks of losing connectivity in case of any technical glitches or physical malfunctioning. It also enhances the control of light signals through the Traffic Control Centre."
"The benefits of the new system include remotely controlling of the timing of traffic signals and managing them to cope with the changes in the traffic flow, which translates into less congestion at intersections.
"The system enables diagnosing & managing faults of light signals to ensure the efficient and optimal functioning of the traffic signals control systems. If there is a need for additional traffic signals, they can be easily and quickly linked with the control center at a cost lower than previously incurred when telephone lines were used," added Bin Adai.
