Metro Detroit is one of the more heavily congested regions for automobile traffic in the nation, as is shown consistently in various national transportation studies.

According to a transportation study by INRIX Inc. (a high tech telematics transportation company) metro Detroit ranked #19 out of the top 100 worst traffic congested cities in the USA... the INRIX study also determined the peak weekly traffic period to be on Friday afternoons between the hours of 5pm - 6pm.

According to another traffic study by the Texas Transportation Institute, the TTI ranked metro Detroit #16 out of the top 20 most congested cities as measured by the number of hours commuters endured in extra travel time during rush hour traffic... the TTI determined metro Detroit residents waste approx. an extra 54 hours per year traveling in local rush-hour traffic.

In a recent Road Rage survey commissioned by AutoVantage, the survey found that Detroit road rage is the 3rd worst in the US as compared amongst a total of 25 major US cities.
