Novia Scotia Trial for AGD’s 343 Highways Radar

When the Ministry of Transportation (Highways Division) in the Canadian province of Nova Scotia was seeking an effective solution to its outdated vehicle monitoring and traffic flow system, it was the team here at AGD that offered the ideal solution.

Having previously relied upon standard inductive loops, The Highways Division was looking for a non-intrusive alternative in order to provide high quality data on vehicular volume, classification, and speed across all lanes of a busy highway.

With a partnership with us spanning more than two generations, AGD’s Canadian Distributor – North Line Canada Ltd – recommended to its client an initial trial of our 343 Highways Monitoring Radar.

The project’s location was Kelly Lake Compliance Station situated on the Veteran’s Memorial Highway route 102, a site that utilised Weigh In Motion Sensors (WIMS) along with high-maintenance inductive loops.

One of the core challenges posed by the Canadian Highways Division was that the highway (which spanned almost 90 metres) was made up of multiple lanes in both directions, which were divided by a large, grassed median.  Being able to set the radar to accommodate an elevation difference of over one metre between the north and southbound lanes was also vital.

Dean Jarvis, AGD’s Commercial Engineer, said: “Our 343 radar was designed specifically to combat the challenges faced by authorities who require their monitoring products to be situated close to the highway itself.  Most radars must be mounted between 5m and 8m from the carriageway, and – particularly on roads where the edge of the highway is close to the built environment – there isn’t always that amount of space available.

“The 343 can be mounted as close as two metres from the inner edge of the inside lane and, due to a bespoke antenna, will still provide information for the lane immediately below the radar, as well as the lane on the farthest point of the carriageway. The 343 is angled at 30o, but it can also monitor up to ten lanes of traffic, looking across both carriageways to detect vehicles travelling in approaching and receding directions – making it the perfect solution for this particular project.”

Following official approval for the trial to proceed at the designated site, the North Line team got to work and completed the installation at the location in less than 45minutes – with all traffic monitoring fully functional within a quarter of an hour of final commissioning.

Jim Sheehan of North Line Canada, said: “When we were approached by the Province of Novia Scotia and asked for assistance, the AGD343 product was an obvious choice as a solution to their very specific needs.

“AGD’s reputation for reliable equipment, intensive quality control, and their highly efficient responses to customer feedback meant that we were extremely confident that the initial installation would be a success – and we’d like to offer a huge thank you to the expert and experienced team on the ground at AGD who ensured a smooth and pain-free transition.”

Subject to a successful trial at the Kelly Lake Compliance Station site, the plans are to undertake further permanent installations of the AGD343 over the next 12 months, with significant numbers of future installations across all current stations across the territory.
