Cost of Congestion in the Trucking Industry

Wednesday, April 27th, 2016
Figure 1: United States NPMRDS Roadway Network

AMERICAN TRANSPORTATION RESEARCH INSTITUTE
Trucks transported nearly 10 billion tons of freight representing over two-thirds (68.8 percent) of total domestic tonnage shipped1, and traveled more than 279 billion miles on the nation’s roadway network in 2014.2 Due to the critical role of safe and reliable truck movements in sustainable economic growth, it is essential to continually monitor and evaluate the efficiency of the national roadway system. A key impediment to nimble supply chains is the level of traffic congestion experienced on U.S. roadways, and the subsequent costs that are incurred due to this congestion.

Monday, April 11th, 2016
Outstanding Engineering - Michigan's "96fix"

96fix was the largest single-season construction project in state history. Reconstruction of the seven-mile stretch of the 40-year-old freeway included the rehabilitation of 37 bridges, installation of LED lighting and storm sewers, and safety improvements. The $153 million project was completed early and under budget, and brought I-96 in line with current standards. Innovative technologies included visual modeling to gain public support for closing the freeway during construction and 3-D design model for fine-tuning paving work. The process saved taxpayer dollars, cut freeway closure time, and improved pavement quality and safety.

Indiana: History and Analysis of Gas Taxes

Thursday, February 25th, 2016
Figure 1. Inflation-Adjusted Gasoline Excise Taxes, USA and Indiana (1932-2015); Figure 2. Sales Tax Cost per Gallon of Retail Gasoline in Indiana (1962-2015)

BALL STATE UNIVERSITY
CENTER FOR BUSINESS AND ECONOMIC RESEARCH
With gasoline taxes static or declining due to inflation, the costs of constructing and maintaining roadways and developing congestion relief has grown. The cost per mile of road maintenance has increased roughly 22 percent since the late 1990s and will certainly continue to grow in the coming years (ITEP, 2013). The real (inflation-adjusted) reduction in the gasoline excise tax reduces the state’s ability to fund highway construction, operations, maintenance and relieve congestion. In addition, there have been other issues that affect the stability of the gasoline excise tax revenue.
