INTELIGHTS: India’s 1st 3-D Smart Traffic Signal launched in Mohali

Mohali traffic police in Punjab have launched India’s first wireless 3-D Smart Traffic Signal System called Intelights. It proposes a Intelligent Traffic Timer Control to regulate traffic signals with smart bird’s eye view using wireless sensor system. It has been installed at traffic crossing near the Airport Road in Mohali on a pilot project basis.


One of the major reasons for traffic congestion is inefficient working of traffic signal timers installed at intersections. Presently, timers of traffic lights display preset value which leads to waste of time. For instance, consider scenario in which traffic signal shows green light for ’20 seconds’ but there is no vehicle present at that particular intersection – thus leading to unnecessary waste of time.

About Intelights

It has been devised by students of Chandigarh university after three years of intensive research. It proposes a 360-degree solution to curb the rising problem of traffic congestion

Working: It uses dynamic signal control technology to adjust timers of red, yellow and green lights according to the traffic density at an intersection. It uses existing CCTV cameras to gather live traffic video feed, and automatically evaluates the traffic density using Artificial Intelligence (AI), and sets signal timers accordingly. This process is repeated for every cycle of traffic lights to keep traffic flowing smoothly.
