Chandigarh, June 1 -- In an effort to rein in late-night overspeeding, the Chandigarh Traffic Police have issued 150 challans between May 19 and May 31 during targeted night-time enforcement drives. The action was taken using advanced Laser Speed Meters, also known as LiDAR guns (Light Detection and Ranging), a tool for accurately measuring the speed of moving vehicles, even in low-light conditions. Speedsters revving up to race through empty roads at night should think again, as Chandigarh Traffic Police have armed themselves with night-vision LiDAR guns to catch such offenders. Launching a crackdown on late-night speeding, a major cause of fatal accidents, traffic police have issued 150 challans between May 19 and May 31. Most speed violations recorded during the speed enforcement drives ranged between 70 kmph and 110 kmph, significantly exceeding the permissible limits on city roads. The drives were conducted daily between 10 pm and 1 am, focusing on key entry points to the city, including Airport light point to Hallo Majra light point, Sector 9/10 dividing road and Transport light point. These locations were identified based on traffic analysis and past accident records, particularly noting a higher incidence of speeding during late hours when traffic is sparse and enforcement is typically more challenging. LiDAR guns, also known as laser speed guns, use light detection and ranging (LiDAR) technology to measure the speed of moving vehicles with a high degree of precision. The Chandigarh Traffic Police currently have six LiDAR speed meters, including advanced models equipped with night vision capabilities. SSP (Traffic) Sumer Pratap Singh said, "Our teams are equipped with laser speed meters that allow them to monitor speeding violations with unmatched precision. These devices work efficiently in the dark and have helped us tighten enforcement during hours when violations tend to spike." The device emits a narrow, pulsed laser beam aimed at a moving vehicle. This beam strikes the vehicle and reflects back to the device. By measuring the time taken for the light to travel to the vehicle and back (a round trip), the LiDAR device calculates the exact distance between the device and the vehicle. By taking multiple distance readings in rapid succession, the system determines how quickly the distance is changing over time, which is then translated into vehicle speed....
