Silver Linings: COVID-19 Thinning Traffic Across the Country

Road traffic across the United States is dropping drastically, thanks to social-distancing efforts taking place to combat the spread of the novel coronavirus. For yours truly, traffic in New York City has gone from frequently hectic to downright pleasurable and relaxed. While there’s a statewide initiative in place to keep residents in their homes, the days leading up to the shelter-in-place order saw a decline in roadway activity I’d only previously witnessed during Hurricane Sandy.

According to INRIX, a Washington-based firm providing traffic analytics, road use in the United States dropped by about 30 percent last week — with regions affected by state-mandated shutdowns seeing even larger declines. The study compares the national traffic volume from the 14th to the 20th of March to volumes recorded between the 22nd and the 28th of February — noting that March 13th was the first day traffic started trending downward in most regions. Moving forward, INRIX says it wants to continue offering up a weekly synopsis of national traffic volume until the health crisis ends.

Regions fared differently depending on when COVID-19 struck and how aggressive local governments responded. For Seattle, that culminated in a 29-percent decrease in motorists on March 20th. Meanwhile, San Francisco witnessed a 51-percent decline as New York City maxed out at 43 percent (which, again, has been lovely).

Major metropolitan areas were hardest hit by the virus since its migration out of China. However, statewide declines in traffic are still noteworthy, with many seeing roads clear by more than the national average of 30 percent. For the most part, people seem to be making the same sort of trips they used to — just at a much lower frequency (as many are opting to stay home). The only exception was said to be commercial traffic.

From INRIX:

Digging a little deeper, so far, the decline in national passenger traffic volume is directly tied to a decline in total trips, with distance-per-trip increasingly slightly from 9.2 miles to 9.4 miles. With the reduction in congestion as reported by INRIX Research, we are seeing slightly shorter trip times, with 18.5 minutes per trip dropping to 17.8 minutes.

A silver lining, if there is one, is that commercial traffic is holding up. Long haul truck traffic is holding steady — a hopeful sign as we clearly need the nation’s logistics backbone to continue to function. Local fleets, such as service vehicles and local deliveries, are experiencing a drop nationwide, slightly under 10 [percent] through the week. These commercial traffic trends bear watching.

Clients included several of the world’s largest automakers, global tire brands, and aftermarket part suppliers. Dissatisfied with the corporate world and resentful of having to wear suits everyday, he pivoted to writing about cars. Since then, that man has become an ardent supporter of the right-to-repair movement, been interviewed on the auto industry by national radio broadcasts, driven more rental cars than anyone ever should, participated in amateur rallying events, and received the requisite minimum training as sanctioned by the SCCA. Handy with a wrench, Matt grew up surrounded by Detroit auto workers and managed to get a pizza delivery job before he was legally eligible. He later found himself driving box trucks through Manhattan, guaranteeing future sympathy for actual truckers. He continues to conduct research pertaining to the automotive sector as an independent contractor and has since moved back to his native Michigan, closer to where the cars are born. A contrarian, Matt claims to prefer understeer — stating that front and all-wheel drive vehicles cater best to his driving style.

    Here on Oahu (where locals who learned to drive here take a perverse pride in giving up the right of way to as many cars as possible and have bumper sticker that read 'Slow down, this ain't da mainland, brah'), H-1 has been wide open and easy. It's normally clogged between 5:30 - 9am and 3-6:30pm or so. Hitting the 55 mph speed limit is normally a sign of no traffic. Right now, if you aren't doing 65 in the right lane, you're gonna get honked at. More motorcycles and sports cars are out on my normal drive. I'm working from home and playing teacher as well, but I still need groceries and what not and head out early (7am). So, while I expected the light traffic, I didn't expect to see the weird, cool, and fast things come out. Saw an old school suicide door Continental on Monday. Yesterday a classic Nissan Z and a first gen RX-7. So many sport bikes. It feels like there is suddenly a ton of somewhat older modded Japanese compacts, older Mustangs and Camaros, and all manner of Corvettes. I even saw a had my first sighting of a Suzuki Kizashi... showroom new look. I think people are just taking out their fun or weird vehicles and driving. Its kinda cool, but I know it means a lot of people aren't working or getting checks. :/

      I really enjoyed Oahu and I think everyone needs to visit Hawaii at least once, same as New York City . Hawaii has multiple islands so you can try different lifestyles . -Nate

    Just before everything shut, I had to be in lower Manhattan, then the next day, Coney Island. Normally a painful two hour slog each way, the 1948 traffic levels allowed me free-flow from upstate to the city. Less than an hour to City Hall, and not even pushing it. Turns out the roadway system works really well with 1/4 the usual traffic, especially the Uber and Lyft idiots being gone. Making the run to Coney Island in less than an hour was a once in a lifetime thing.....and I wasn't even trying hard or pushing beyond my normal pace + 10/15 mph.

  • Brian Uchida Laguna Seca, corkscrew, (drying track off in rental car prior to Superbike test session), at speed - turn 9 big Willow Springs racing a motorcycle,- at greater speed (but riding shotgun) - The Carrousel at Sears Point in a 1981 PA9 Osella 2 litre FIA racer with Eddie Lawson at the wheel! (apologies for not being brief!)
  • Mister It wasn't helped any by the horrible fuel economy for what it was... something like 22mpg city, iirc.
  • Lorenzo I shop for all-season tires that have good wet and dry pavement grip and use them year-round. Nothing works on black ice, and I stopped driving in snow long ago - I'll wait until the streets and highways are plowed, when all-seasons are good enough. After all, I don't live in Canada or deep in the snow zone.
  • FormerFF I’m in Atlanta. The summers go on in April and come off in October. I have a Cayman that stays on summer tires year round and gets driven on winter days when the temperature gets above 45 F and it’s dry, which is usually at least once a week.
  • Kwik_Shift_Pro4X I've never driven anything that would justify having summer tires.
