Cohda Wireless has demonstrated a smart street light concept at the Intelligent Transport Systems World Congress in Copenhagen that has been designed to alert motorists to the presence of broken-down vehicles.

The streetlight system proposed by Cohda Wireless will see the luminosity of the street light increase from 20% to 100% intensity to alert motorists that a car has broken down in the immediate vicinity of the light.

Cohda Wireless CEO Dr Paul Gray explained that the concept could utilise connected smart city infrastructure to make roads safer by highlighting a significant road hazard, encouraging motorists to slow down and be more alert, thereby reducing the risk of an accident.

“Broken-down vehicles present a significant risk to all road-users, more especially on freeways and motorways when its dark or where there are blind rises or bends,” explained Dr Gray.

“Our concept proposes that an on-board application in the vehicle sends a notification via DSRC to the nearest streetlight to the car that has broken down.   The streetlight, which has been fitted with hardware that receives and interprets the message, sends a message to the controller of the smart street light, typically in the Cloud, which in turn responds by increasing the luminosity of the street light until the vehicle leaves the scene under its own power or is towed away.”

“There are many smart street light initiatives around the world that are focused on connecting street light infrastructure and enhancing control functionality.  This is about Vehicle-To-Infrastructure technology plugging into these networks to enhance road safety.”

“It’s a relatively simple concept, but it could save lives.” added Dr Gray.
