Road Traffic Information is a key component of the modern Intelligent Transportation System and signaling systems have a significant role to play in optimising traffic efficiency as they allow travelers to navigate safely through the road network and prioritise the direction and coordination of travel at peak times of the day.

Sensor technologies can be deployed to contribute real-time information about traffic occupancy and efficiency that can be used to enhance flow and journey time, allowing large numbers of road users to pass through the road network with minimal delays.

Staying on top of the ebb and flow of traffic coordination requires up-to-minute data and intelligence. Ventia currently programs and monitors all traffic signals in the WA roads network to ensure safe and efficient operation.

By monitoring and centrally controlling vehicle movement through signaling and sensor information we can manage congestion, reinforce speed limits and control safety outcomes, and have a positive effect on the environment, reducing greenhouse emissions by better managing traffic flow to minimise stop/start driving.

At Ventia we can plan, procure, install or upgrade, program, operate, coordinate and test complete traffic signal systems, plus establish back up batteries and protocols for urban and interurban roads, bridges and tunnels.

Signals optimisation is achieved through the SCATS system designed to coordinate and monitor the entire signals network. Using NGEN Adaptive engineering software we can program signals from a Windows’ system. The Wintraff PC based platform enables monitoring of signals to ensure performance to design specifications, with all input and output functions operating correctly.

As a key component of any Intelligent Transport System, signaling can be provided as one part of a wider, end-to-end ITS solution or tailored as a unique offer to clients.

Our Capabilities include:

Programming and monitoring of all traffic signals for safety and efficiency
Optimisation of signals by adjusting timings as required
Trial of new technologies
Issue of technical updates
Advice on phasing and signals operation
Training provision on all aspects of traffic signals operation
Design of traffic signals, design verifications and peer reviews
Provision of technical documentation to complement supported software packages, and
Expert witness advice to police, investigators, lawyers and the courts.

Carrying more than 180,000 vehicles a day, the West Gate Freeway is one of Victoria’s major arterials.

VicRoads sought a partner to develop a Managed Motorway system that would improve the travel experience between Williamstown Road and the M80 Interchange. The system would also need to link to other existing ITS systems operated by VicRoads.

Ventia was awarded this contract in 2013 and brought its considerable, proven and successful experience working with VicRoads to upgrade, design, construct, integrate and maintain traffic management systems throughout the state.

The purpose of the West Gate Managed Motorway Project was to upgrade the ITS to enable VicRoads to:

better manage traffic flow
improve reliability and safety
create a smarter road.

To help VicRoads achieve the project outcomes and improve traffic flow for Melbourne’s motorists on one of Australia’s busiest roads, Ventia applied its existing, contemporary experience to design a system that integrated with the existing ITS. Construction was completed in 2014 and included the longest gantry in the Southern Hemisphere.

Key features of Ventia's integrated solution for VicRoads include:

Lane use management signs and associated gantries (including the longest gantry in the Southern Hemisphere)
Non-intrusive traffic data collection stations
CCTV cameras
Supporting ICT infrastructure including active equipment, fibre network, pits cabinets and conduits
Integration of new section of ITS equipment into the existing ITS FMS network including communications links and access switches
Power systems and reticulation.
