Tambaram to Tindivanam NH to be monitored by IoT; 1st in TN
Chennai: The 90-km Tambaram-Tindivanam stretch on NH-32 will soon become Tamil Nadu's first highway to be fully integrated with NHAI's Internet of Things (IoT) network. As part of a pilot project, all lights along this route will be fitted with sensors linked to GPS and a central dashboard at NHAI's Chennai regional office.

Currently, each streetlight functions independently, with manual switch. Workers often leave the lights on for 24 hours or switch them on prematurely in the afternoon, leading to unnecessary power consumption. "We've noticed some lights on even in broad daylight. It's a waste, especially since we pay tolls," said R Raghavan of Madurantakam.
Under the upcoming system, sensors and timers will automatically calculate the daily duration of sunlight based on location and operate the lights only when needed.
The dashboard will record illumination required versus what was actually provided, allowing officials to assess lighting coverage across the full stretch without physical checks, said a senior NHAI official.
NHAI will use IoT data to track movement of ambulances, patrol vehicles, and recovery cranes. The system logs how quickly these services respond to accidents and flags delays or failures in deployment. Geo-fencing will ensure patrol vehicles stay within designated zones; any breach will prompt alerts and contractor accountability, the official said.
However, frequent commuters remain unconvinced. "While technology is fine, the highway still lacks basic safety features. Road markings have faded, and accident-prone spots are left unattended," said G Ganesh of Sngaperumalkoil.
