U.S. Department of Transportation Study on Traffic Flow
The U.S. Department of Transportation conducted a study to measure the rate of traffic flow in the United States. According to USDOT, the average rate of traffic flow was calculated to be about 50 miles per hour. However, there are many factors that can affect this rate, including the time of day, the type of road, and the weather conditions. USDOT officials used a variety of methods to measure the rate of traffic flow. They looked at the number of cars on the roads, the amount of time it took for cars to travel certain distances, and the average speed of cars. They also looked at how often accidents occurred and how long it took for emergency vehicles to respond to them.
