It seems this is the summer of road trips, with gas prices at their lowest point in six years.

Prices are roughly a buck cheaper per gallon than in 2014, which means an average American household will spend about $700 less for gas in 2015 than last year. In total, Americans are going to save about $65 billion on gas this year.

The last time gas prices were this low was in 2009. But with the recession taking its toll, few people were in a mood to travel. This year, however, travel is a top agenda for Americans, who are all set to contribute to the $8 trillion global travel and tourism industry.

According to the U.S. Energy Information Administration, gas will average $2.43 a gallon in 2015, while last year it averaged at $3.59 per gallon. The EIA's latest average from July 27 has gas priced at $2.75 per gallon, and it may even drop back down around $2,00 across the country after summer.

With annual vehicle fuel expenditures to fall to their lowest level in 11 years, more families will be encouraged to plan road trips for their vacations. Along with obvious savings, this could mean a big boost for the economy.

As people take more trips, hotels and B&B's, bars and restaurants, America's great national parks and amusement parks are gearing up for brisk business, not just this year but into 2016 as well. More than anything, consumers are set to splurge on various travel apps, advanced GPS systems for updated traffic information as well as the nationwide atlas road map.

According to AAA, cheap gas is going to send more cars onto America's highways. Memorial Day road traffic was up by 5.3 percent this year, which actually amounted to a staggering 33 million road-trippers, the highest number in a decade.

Everyone is excited about the cheap gas prices. With the job market improving, it seems to a great time to plan more trips. Yet the recession made people more cautious about spending.

Low gas prices are a big boon since consumers can now go a vacation without spending a bundle. As they take to the roads in record numbers, astounding figures are coming in from all corners.

An estimated 35.5 million people drove 50 miles or more from home during the July 4 weekend. The first four months of 2015 saw a record 987.8 billion miles of driving on American roads.

According to the AAA, drivers and road trips will account for 85 percent of travelers in 2015. A strong employment market, recovering economy and rising income have already prompted a lot of vacation plans this year, and cheap gas prices will act as an icing to finalize those plans.

Why are gas prices so low? Bankrate has the answer to that. The world is expected to have more oil on hand than it needs this year, which will in turn make gasoline, diesel and other petroleum-based fuels cheap and affordable. The cheapest gas can be found near the refineries of the Southeast, while West Coast residents will pay higher fuel prices this summer.
