'Just devastating': New data confirms Gardiner construction eroding commercial travel times

Data reveals impact of Gardiner construction Data from telematics giant Geotab revealed construction on the west end of the Gardiner has more than doubled commuter time.

Commercial travel times on the Gardiner have increased a whopping 250 per cent during the morning rush hour since the latest round of expressway repairs began two months ago, new fleet tracking data reveal.

Oakville-based telematics giant Geotab Intelligent Transportations Systems harnessed artificial intelligence, along with GPS and on-board diagnostic technologies, to assess the impact of the Dufferin-to-Strachan construction on business productivity – and the hard data confirm the anecdotal tales of grievous gridlock caused by the latest lane restrictions.

“Certainly, there's that massive slowdown there,” Mike Branch, Geotab’s Data and Analytics Vice-President, told CTV Toronto at the Oakville data centre.

“And we thought, you know what – let's have a look at the data. Let's discover it a little bit, see what we can find there.”

Comparing the travel times and patterns of 10,000 vehicles during the months before and after the construction began, Geotab revealed that commercial drivers are now spending 80 per cent more time driving per day on the Gardiner.

During the 7 a.m.-to-10 a.m. morning commute, travel times increased by up to 250 per cent, while during the afternoon rush hour travel times grew by up to 230 per cent. Average drive times were most impacted around 8 a.m.

“The numbers are staggering, but they’re not surprising,” Toronto Councillor Brad Bradford said Thursday. “It confirms what we’ve been hearing from residents across the city, and in fact the entire region.”

“A 250 per cent increase in travel times during peak periods is just devastating.”

It now takes an average of 20 minutes, up from eight, to get from the Humber River to Strachan Ave.; the travel time from Jarvis St. to Dufferin St. has increased to 25 minutes from 11.

“It's a huge drop from a productivity perspective,” Branch said. “We’ve got fleets doing last-mile delivery, right, service and repair. So you can think about – imagine the person sitting in the vehicle, spending that much more time on the road, what it does to them mentally, what it does the productivity of their work day.”

“We knew that there were going to be massive economic impacts,” Jen van der Valk, senior vice-president at the Toronto Region Board of Trade said Thursday.

“We’re hearing from our members that it’s having them rethink their footprint, their office footprint downtown, which is also detrimental to our downtown core and the thriving economy.”

The 700-metre stretch of aging expressway is undergoing the second of six phases of rehabilitation work, as crews replace the elevated bridge and repair the supporting structures underneath. The resulting 30-per cent cut to lane capacity affects an estimated 200,000 vehicles a day, according to the City.

Geotab reports that the amount of commercial traffic travelling less than 25km per hour has doubled since the construction began, and that the top three alternate roads – Harbour St., Lakeshore Blvd., and Cherry St. – have seen an average traffic increase of 43 per cent.

The heightened travel times have also had a serious impact on emissions, causing an additional 1,200 kg of carbon dioxide a day – a 23 per cent increase, according to the data.

The lane restrictions were originally scheduled to be in place for three full years, lifted only during the FIFA World Cup tournament in 2026 – but in the wake of driver outcry, Toronto City Council voted in May to explore accelerating the construction schedule.

City staff have been directed to examine the feasibility of 24-7 repair work, among other strategies.

Mayor Olivia Chow said Thursday that “it’s all hands on deck” in the push to mitigate the impacts of the construction.

“There’s a team that are meeting urgently, together with the provincial government, they’ve been extremely cooperative,” Chow said. The [Transportation] Minister and I have met twice on it, and we are pooling all our resources together, both the province and the city, and bringing in international experts to assist us. “

Branch, meanwhile, stresses that the stats and the science exist right here in the GTA; City Hall simply needs to leverage the technology to help solve the congestion conundrum.

“We have access to this data at-scale, privacy-compliant, all aggregate, that we can help use to make some really intelligent decisions. So it’s management by measurement,” he said.

“We can use management by measurement to help keep Toronto moving."
