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 is a global leader in the development of Connected Autonomous Vehicle (CAV)
software with proven applications for Smart City, Mining and other environments. Cohda’s
technology connects vehicles with infrastructure and pedestrians to make our streets, cities and
working environments safer, smarter and greener. Cohda is headquartered in Australia and has
offices in Europe, China and the USA.

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
