After replaced by Honolulu a year is part of the country again, Los Angeles deserves the title of the most crowded Metro. 17 On a Friday in the year 2012, the average driver wasted more than 28 minutes in traffic according to INRIX traffic information and services group, which collects data for individual sections of the road.
In his 2012 traffic scorecard found INRIX that traffic at peak hours on Interstate 405 in Los Angeles drew only 14 miles per hour, 26 minutes add, what should be an eight-minute drive. Last year, the average American 38 hours wasted sitting in traffic; but for those, the life of the nation's most congested cities, jumped this number to 42 hours.
Not surprisingly, population density contributes to traffic congestion. Is overloaded by the 10 metro areas with the highest population density in 2010 six among the 10 of the nation's most.
INRIX generates a stowage factor, which is a compilation of factors such as population density, that average time spent commuting and the percentage of the population who drives to work.
In terms of the longest average commute daily, New York captured the honor with an average of 34.9 minutes. Washington, D.C. was second in a close at 34.5 minutes. But the availability and use of public transport the cities down to the top 10 list.
The congestion index is a metric of how long travel takes the average driver during rush hour when traffic is clear. Los Angeles has a congestion index of 28.8, meaning that that it takes 28.8 percent longer to make a trip during peak hours traffic jams as it does when there is no traffic.
This year on the most congested cities (with their congestion index in brackets):
1. Los Angeles (28.8)
2. Honolulu (26)
(3) San Francisco (23.5)
4. Austin, Texas (20.7)
5. New York City (19.9)
6 Bridgeport, Connecticut (19.1)
7, California (17.6)
8 Seattle (17.6)
9 Washington, D.C. (16.4)
10 Boston (14.7)
INRIX scale is supported by other surveys. Researchers at Texas A & M transportation Institute recently released its urban mobility report and similar results found.
In the Texas A & M rankings, Washington, D.C. leader, followed by Los Angeles, San Francisco-Oakland, New York-Newark and Boston. The second five are Atlanta, Chicago, Philadelphia, Houston and Seattle. The urban mobility report contains a detailed presentation of the traffic problems in total 498 U.S. cities.
Overloading is frustrating, but researchers have found that it is also expensive - for the company and drivers.
"We all understand that the journeys take longer time, rush hour, but for really important dates, we have more and more time to ensure an on-time arrival," said Bill Eisele, TTI researchers and report co-author. "How traffic jams are so bad that it even more frustrating is that you cannot rely on the consistency of daily traffic jams. "These unreliable travel is expensive for commuters and truck drivers were move."
The 2012 report of estimating the attributed to congestion additional carbon dioxide emissions: ?56 billion--about 380 pounds per car commuters.
Moreover, the amount of fuel was wasted in congested traffic 2.9 billion gallons - enough, four times to fill the New Orleans Superdome. This is the same as 2010, but behind the 3.2 billion gallons are wasted in 2005.
The financial cost for congestion in the year 2011 was $121 billion, up $ 1 billion from the previous year, or $818 per commuter. It was about 27 billion $ value wasting time and diesel fuel from the truck of goods on the system.
