IPL intersection safety improvements come to light for road users

Challenge

The Panalatinga Road exit ramp from the Southern Expressway forms part of a busy intersection, with some 30,000 motorists passing through it each day.

The intersection sees four major roads meet, along with a pedestrian crossing serving a nearby park and ride, and the multiple lane markings can be a source of confusion for drivers.

To further improve the safety of the intersection, SAGE Automation was engaged by the Department for Infrastructure and Transport (DIT) to design an in-pavement lighting system that easily identifies lane boundaries for motorists.

Solution

SAGE Automation completed the design, supply and installation of LED lights and controllers to improve wayfinding using an in-pavement lighting (IPL) system.

Following a comprehensive in-house testing period, the supplied lighting solution was installed.

The installation of the IPLs was completed in conjunction with SAGE Group company Traffic Control Systems, requiring night works to minimise disruption to road users.

Outcome

In-pavement lights (IPLs) were activated on the Panalatinga Road exit ramp in May 2020.

The IPLs link to the intersection’s traffic signals and activate when traffic is passing in the direction of the lighting. Using LED lighting focused in the motorists’ line of sight helps to provide guidance through the intersection by illuminating the direction of travel during a green light sequence.

The IPLs improve visibility for road users and allow drivers to easily navigate the intersection, especially during low light and poor visibility conditions.
