New South West Roads and Maritime Services has relied on Coates Hire’s JamLogic Traffic Control System to ease holiday period congestion on the Pacific and Princes Highways for the second year in a row.
“JamLogic is the name of the software used to control our fleet of variable message signs (VMS),” explains Jarrad Whitby, Coates Hire Major Project Manager – Events.
“Its capabilities now allow us to offer the most advanced traffic control systems in Australia.”
The NSW RMS North Coast Region uses a JamLogic Automatic Queue Warning System to monitor holiday traffic flows on the Pacific Highway at Macksville. This section of the highway is susceptible to congestion when road works are underway.
The system uses radar speed sensors to monitor the speed of the traffic on the highway and feed this data into the web-based JamLogic software.
The software, using complex algorithms, predicts when the traffic will start to slow, stop and bank up throughout the monitored stretch of road.
It then automatically changes the messages on the upstream VMS to warn motorists that traffic ahead is slowing, or is stopped. This helps to prevent rear-end collisions by keeping motorists informed of traffic conditions ahead.
JamLogic also sends emails or SMS alerts to RMS staff when traffic is slowing or stopped, and again when it is free flowing.
This feature saves the RMS costs by removing the need to have staff out monitoring the traffic at peak flow times, Whitby says.
“When sensors register an average traffic speed of, say, 60 kilometres an hour and a traffic volume close to a pre-set figure, then JamLogic will automatically change the message on the upstream VMS to something such as ‘Queuing traffic ahead. Prepare to stop’.
“If the sensors farther along the road detect that the volume in a specific period has increased and the speed has dropped to another threshold such as 40 kilometres an hour, then JamLogic might change the VMS to read ‘Stopped traffic ahead. Prepare to stop’.
“It really can be any message that the operator chooses to put into the system.”
Coates Hire has also deployed an advanced Travel Time Information System along the northern sections of the Pacific Highway.
The system calculates the speed it takes for vehicles to travel along a section of road and then posts these travel times on upstream VMS. This gives motorists up-to-date information on the conditions ahead and an indication of the time it will take to reach certain locations.
The calculations are made by tracking the Bluetooth signature of vehicles travelling along the route and the time it takes them to reach certain points.The system is even smart enough to filter out instances where people pull off to the side of the road for a break.
“The RMS places great importance on keeping motorists informed of traffic conditions and they are impressed with JamLogic’s performance,” John Annison, Coates Hire National Product Manager – Traffic Management, reports.
“JamLogic is a great value-add to our existing traffic management customers. Coates Hire is leading the market in its deployment.
“JamLogic can also be configured to interface with a multitude of different sensors, including CCTV cameras, weather stations, and vehicle over height sensors, so there are many applications for the technology,” Annison says.
“The systems we provide can offer real safety benefits to road authorities and major contractors around road works, accident black spots and also major events.”
