If it seems like there's more traffic in your everyday travel than there was in recent years, your eyes aren't deceiving you. The Federal Highway Administration's latest "Travel Trends" report says the miles covered by American drivers have been increasing for 14 months in a row.

The report, estimating travel in the United States for April, says that drivers covered 267.9 billion miles over the course of the month. This tally marked a 3.9 percent increase from April of 2014, or 10.2 billion additional miles.

The FHWA says the seasonally adjusted total for the month is 262.4 miles, which is a slightly smaller increase—3.7 percent, or 9.5 billion miles—over the previous year. April's travel total was also 1.1 percent higher than March's total.

A new record was set for the cumulative total for the first four months of the year. In 2015, the distance traveled in by U.S. drivers between January and April totaled 987.8 billion miles. The previous record was set in 2007, when drivers tallied up 965.5 billion miles.

The moving 12-month total also exceeded 3 trillion miles, the first time this has occurred in April since 2008. The total estimated distance traveled over the course of the year in this tally was 3.07 trillion miles, while the figure in April of 2008 stood at 3.03 trillion miles.

The Northeast region—consisting of the New England states as well as New Jersey, New York, and Pennsylvania—had the smallest year-over-year increase at 2.4 percent. Travel in this region increased from 36.08 billion miles in April of 2014 to 36.96 trillion miles in April of this year.

Connecticut travel increased 1.4 percent, from 2.48 billion miles to 2.51 billion miles. This included a 1.2 percent increase on urban arterial roads, from 1.76 billion miles to 1.78 billion miles, and a 2.3 percent increase on rural arterial roads, from 164 million miles to 168 million miles.

The 12 states of the North Central region had the largest increase in travel, with the distance covered increasing 5.2 percent since last April. Travel in this region totaled 60.5 billion miles, a year-over-year increase of about 3 billion miles.

In the 13 states of the Western region, travel increased 4 percent to 60.86 billion miles. Travel in the South Atlantic region, which includes eight states and the District of Columbia, went up 3.5 percent to a total of 56.1 billion miles. In the eight states of the South Gulf region, the total distance traveled increased 3.5 percent to 53.5 billion miles.

Indiana had the largest increase in travel among the states, with drivers covering 14.8 percent more miles in April than they did the year before. The total distance traveled in the month was 8 billion miles, about 1 billion more than in April of 2014.

Hawaii had the second most significant change in travel, with the distance covered increasing 8.1 percent to 1.1 billion miles. North Dakota had the third largest increase, going up 7.4 percent to 992 million miles.

Washington, D.C. had the only year-over-year decrease in overall travel in April. The distance covered in the District of Columbia dropped 0.3 percent, from 301 million miles to 300 million miles.

Other areas saw individual decreases on certain routes. Maine had the largest drop in urban arterial traffic, falling 1.8 percent to 193 million miles. Urban arterial traffic in the District of Columbia decreased 0.3 percent to 214 million miles, while Louisiana's urban arterial traffic fell 0.2 percent to 1.97 billion miles.

The Traffic Volume Trends reports are based on hourly traffic count data collected from about 4,000 locations across the nation. The change in the percentage of traffic is compared with the same month in the previous year to estimate the total distance traveled by drivers in the state. The FHWA says that due to the limited sample size, a more accurate count is provided annually by the Highway Performance Monitoring System.
