Additionally, the agency\u2019s research suggested that an array of small-scale, lower cost solutions could provide travel time benefits for both trucks and passenger vehicles.<\/span><\/p>\n<p><span lang=\"EN-US\">Snarled traffic is estimated to have caused the trucking industry to consume an additional 6.87 billion gallons of fuel in 2016 \u2013 representing approximately 13% of the industry\u2019s fuel consumption, while adding $15.74 billion to its fuel bill. From an environmental standpoint, congestion also resulted in 67.3 million metric tons of excess carbon dioxide (CO<\/span><sub><span lang=\"EN-US\">2<\/span><\/sub><span lang=\"EN-US\">) emissions being emitted into the atmosphere.<\/span><\/p>\n<p><span lang=\"EN-US\">The resulting study, entitled \u201cFixing the 12%\u201d examines the potential fuel consumption and emissions benefits.<\/span><\/p>\n<p><span lang=\"EN-US\">\u00a0which could be derived from improvements to an interstate interchange in Atlanta, Georgia that costs commuters and the trucking industry millions of dollars each year due to congestion.<\/span><\/p>\n<p><span lang=\"EN-US\">Looking specifically as an example at the intersection of Interstate 285 and Interstate 85 in northern DeKalb County, Georgia \u2013 consistently ranked as one of the worst traffic bottlenecks in the US \u2013 ATRI utilized its truck GPS database to identify average truck speeds by time of day through this intersection, with vehicle positions and speed data and found that average vehicle speeds during the weekday morning commute (7-10 a.m.) slowed to as little as 28 mph, while the evening commute (3 to 7 p.m.) dropped to a low of 14 mph. <\/span><\/p>\n<p><span lang=\"EN-US\">The average speed during these weekday peak periods is 23 mph while the average during weekday non-peak periods is 47 mph, still below free-flow conditions. The overall average speed throughout the weekday at this interchange is 40 mph, while weekend speeds average 49 mph overall, with average hourly speeds as low as 37 mph. Taking that data, ARTI researchers then estimated the fuel consumption and emissions benefits of improving the interchange in terms of fuel consumption and emissions from existing traffic conditions and comparing them to an assumed free-flow condition.<\/span><\/p>\n<p><span lang=\"EN-US\">The results showed that if improvements to the interchange were made to allow the free-flow of traffic, increasing average vehicle speeds to 55 mph, the change could save a projected 4.5 million gallons of fuel annually among the vehicles passing through the project area. This is equivalent to a fuel economy increase of 7%\u00a0for gasoline vehicles and nearly 11%\u00a0for diesel vehicles, the study noted.<\/span><\/p>\n<p><span lang=\"EN-US\">According to ATRI these reductions in fuel consumption and emissions illustrate the potential ancillary benefits which could be achieved by making road improvements which eliminate or reduce congestion at this interchange as well as others throughout the nation.<\/span><\/p>\n<p><span lang=\"EN-US\">The full study can be downloaded<span class=\"apple-converted-space\">\u00a0<\/span><a href=\"https:\/\/truckingresearch.org\/2019\/03\/01\/fixing-the-12-case-study-atlanta-georgia\/#.XH7L-lxKg2x\">here.<\/a><\/span><\/p>\n<p><span lang=\"EN-US\">The full HDT article can be <a href=\"https:\/\/www.truckinginfo.com\/326494\/atri-study-only-12-of-interstate-miles-cause-89-of-traffic-congestion\">found here<\/a>. <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Congestion is a relatively \u201csmall\u201d problem with massive consequences for the trucking industry, according to the American Transportation Research Institute (ATRI) Research Advisory Committee.
