They do data collection, here's the 2011 report showing traffic volumes and origins:
https://fraseropolis.com/wp-content/...dy-summary.pdf They use license plates to find origins. This report doesn't show the 6% figure I quoted as that's for every road into downtown - the math for that shouldn't be at all surprising (count up the number of lanes going into downtown and no one - about 22 by count and 6% sounds about right)
The data shows only about 7% of trips originate from Surrey or Langley while 44% of them come from within Vancouver (22% from Burnaby/New West)

The Viaduct itself is rarely ever the problem, but instead it's the feeders and exit that causes the issue.
Venables cannot flow that many cars, with it being single lane, set to 30km/h (not that anyone observes this), the extremely broken pavement, and the multitudes of lights flowing on and off.
Dunsmuir is regularly backed up because of the lights and the lack of a dedicated right turn lane which many times ends up limiting it to a 1 lane road as well, and also the taxis/ubers that insist on boarding and unboarding where they aren't supposed to.
Georgia and out is the only route which it can sustain the rate that the viaduct can flow, and that side also has 3 lanes unlike the constricted 2 lanes on the entry side. The bike lane is cool, I've used it a few times, but I don't know if it actually flows that many commuters. |
This is one of the better reasons for getting rid of the viaducts - the existing road network around it was never designed (and never will be) to support highway volumes which is what the viaduct was built for (like the Granville Bridge it was designed for a highway system that never got built). If the surrounding network can't use the capacity that's there and there's no way there ever will be capacity to support it why do we keep it?
That said, the proposed replacement road is actually larger than the viaduct so it should flow better. It's just that you'll hit a couple traffic lights because it's part of ground level.

You are probably right that it may only add 5-10 mins to the commute. But my commute to DT is only 15-20mins if I drive, 5-10min is a lot of time. Call it NIMBYism, but due to pick up and drop off, I would tend to drive if I commute into DT. |
The reports I've read say the removal would increase commutes by a maximum of 3 mins. That also sounds about right as the replacement road will be larger but with a couple lights in place. Even if they're wrong by a factor of 2 that's still just 6 mins for a maximum of 6% of the trips being made into downtown. In exchange we get 33 acres of new park space, lands we can develop on and we can reconnect the two sides of Main Street again.

EDIT: just briefly skimmed that PDF, it was penned a decade ago, and the data gathering is older than that. The viaduct now is definitely busier than back in 2013. |
The linked report (which is from 2011) shows trips into downtown were down 15% between 1996-2011. I don't have current data handy but I have seen it and data consistently shows that trips are DOWN into downtown, not up. This is generally true for most of our roads (the Massey tunnel is an example of this that I've seen the data on).
Even in places where volume is up, it's not by as much as we think. It's things like construction (roadwork, housing), and different timing of the volume that are causing congestion that we're seeing (like the mess at Brentwood).

I’m sure reports are always incredibly accurate given the interests involved. The the people facilitating those reports.. |

They do not.
