The Connecticut Department of Transportation recently released data on the number of vehicle miles traveled daily on various road types throughout the state. The data is available on the state data portal.
Trend CT has played with this data before as part of a correlation quiz game, but wanted to take a closer look.
Looking at the map above, it’s apparent that the number of interstate miles driven per town is higher where there are interstates that intersect, as in Hartford, New Haven and Greenwich.
Roads such as Route 2 through Glastonbury or Route 9 in Middletown are considered “freeways” because they have more local exits and a lower speed limit compared to an interstate.
Hartford is the single busiest municipality with more than 1 million daily vehicle miles, followed by Windsor and Greenwich.
More than 700,000 miles were driven daily in Trumbull and 500,000 in Glastonbury.
Focusing just on local roads, Stamford, Fairfield and Danbury were the three towns with the most daily vehicle miles driven, at 190,000, 165,000, and 155,000 respectively. Southwestern Connecticut in general has the most daily vehicle miles traveled.
Unsurprisingly, there’s a high correlation (.78) between the population of a town and the daily vehicle miles traveled on local roads.
Does that translate to more traffic stops by police?
It looks like the answer is no. The correlation is only .29.
