Traffic on Wisconsin roads has decreased dramatically because of the COVID-19 pandemic, according to a new report from the Wisconsin Policy Forum.

“We expected that the drop off in traffic would be most concentrated in the Milwaukee area and maybe the Madison area much more than other parts of the state where there haven’t been very many COVID-19 cases,” said Joe Peterangelo, the Policy Forum’s lead researcher. “But we actually found a pretty consistent drop off in traffic throughout the entire state.”

The data was collected from 61 different locations along interstates and highways throughout the state by the Wisconsin Department of Transportation.

There has been a 41.6 percent decrease in the southeast part of state, a 40.9 percent decrease in the southwest, a 36.1 percent decrease in the northeast, a 37.4 percent decrease in the north central part of the state and a 37.7 percent decrease in the northwest.

Data on traffic on local city streets is not known at this time.

Peterangelo said the decrease started when Gov. Tony Evers’ administration closed K-12 schools March 13. Evers declared his “Safer at Home” order on March 24.

According to the Policy Form, the decline could have potential impacts on the economy, public health, and traffic safety.

Forty percent fewer cars on the road could likely mean there are fewer crashes, injuries, and fatalities. Peterangelo told WPR the preliminary data for March of this year compared to March of last year suggests fatalities may not have improved, but he says it’s too early to tell.

“If people are driving faster — and speed is such a big impact on the likelihood of a fatality — it may not matter that there are fewer drivers on the road,” Peterangelo explained. “It may still be just as many fatalities.”

The drop in traffic could likely impact state revenue as well. Wisconsin has a gas tax of about 31 cents per gallon, so with people filling up at the pump less often, Peterangelo said, that could mean a financial hit for state government.

“The gas tax makes up more than half of the state’s revenue that go into it’s transportation fund,” Peterangelo explained. “The transportation fund is how the state pays for highway projects and local road projects throughout the state.”

Without that revenue, the state may struggle to carry out those projects.

Peterangelo said the Wisconsin Policy Forum is going to keep track of the traffic information as well as look into other impacts of the coronavirus pandemic.

“Things like air quality,” he said. “One of the silver linings is reduced driving may be improving air quality and there have been reports of that, but we don’t have the data to be able to talk about that.”
