VOC, Congestion & Safety

TRIP
With a current unemployment rate of 7.4 percent and with the state’s population continuing to grow, California must improve its system of roads, highways and bridges to foster economic growth and keep businesses in the state. In addition to economic growth, transportation improvements are needed to ensure safe, reliable mobility and quality of life for all Californians. Meeting California’s need to modernize and maintain its system of roads, highways and bridges will require a significant boost in local, state and federal funding.

Highway Boondoggles: Wasted Money and America’s Transportation Future

Monday, September 22nd, 2014
Figure ES-2. Vehicle-Miles Traveled per Capita in the United States, 1946-2013

U.S. PIRG EDUCATION FUND
Americans drive no more in total now than we did in 2005, and no more on average than we did at the end of Bill Clinton’s first term as president. The recent stagnation in driving comes on the heels of a six decade-long Driving Boom that saw steady, rapid increases in driving and congestion across the United States, along with the investment of more than $1 trillion of public money in highways…But even though the Driving Boom is now over, state and federal governments continue to pour vast sums of money into the construction of new highways and expansion of old ones—at the expense of urgent needs such as road and bridge repairs, improvements in public transportation and other transportation priorities.

21st Annual Report on the Performance of State Highway Systems

Friday, September 19th, 2014
Table ES1: Performance of State-Owned Highways, 2009–2012

REASON FOUNDATION
Reason Foundation’s 21st Annual Highway Report tracks the performance of the 50 state-owned highway systems from 1984 to 2012. Each state’s overall rating consists of 11 category rankings. The rankingsinclude highway expenditures, Interstate and rural primary road pavement conditions, bridge conditions, urban Interstate/freeway congestion, fatality rates and narrow rural arterial lanes. The study is based on spending and performance data submitted by the state highway agencies to the federal government. It also reviews changes in highway performance since 2009, the prior report’s focus.

Travel time is an important performance measure used to assess the traffic operational quality of various types of highway facilities. Previous research funded by the Florida Department of Transportation (FDOT) on travel time reliability developed, implemented, and evaluated tools for estimating travel time reliability for freeways and arterials. Previous research efforts have also compared the model-estimated travel times to field-measured travel times.

Figure 1. Reclaimed material use, 2013.

ILLINOIS CENTER FOR TRANSPORTATION
The Illinois Department of Transportation (IDOT) has many years of experience using a variety of reclaimed and recycled materials in highway construction. Major material use in highway construction is in the form of aggregates, concrete, and hot-mix asphalt (HMA). It should be no surprise that reclaimed and recycled material use is aligned with usage of these basic construction materials. This report presents the quantity of materials used in 2013, along with specific reporting as required in Illinois Public Act 097-0314. Specific reporting on use of shingles, along with efforts to reduce the carbon footprint and to achieve cost savings through the use of recycled and reclaimed materials, in asphalt paving projects is presented.
