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.

A Global High Shift Scenario: Impacts And Potential For More Public Transport, Walking, And Cycling With Lower Car Use

Thursday, September 18th, 2014
Figure 7: Total Urban Passenger Travel for Select Countries/Regions

INSTITUTE FOR TRANSPORTATION & DEVELOPMENT POLICY
UNIVERSITY OF CALIFORNIA, DAVIS
This report is the first study to examine how major changes in urban transport investments worldwide would affect urban passenger transport emissions as well as mobility by different income groups. It starts with the most recent United Nations urban population forecasts and the most recent model framework and forecasts used by the International Energy Agency (IEA) for global mobility modeling. The study extends these with new research on the extent of various urban passenger transport systems in cities across the world, as well as new estimates of the extent of mobility by non-motorized transport and low power e-bikes.

Renewable Energy in the Western States

Wednesday, September 17th, 2014
ELECTRICITY GENERATION BY SOURCE, 2013

AMERICAN COUNCIL ON RENEWABLE ENERGY
With the growing prominence of renewable energy in the western power, heat, and transportation sectors, states are implementing and exploring technology and policy options to effectively manage its production and use. Renewable energy is now responsible for over 20% of electricity generation in six western states, and the region saw the addition of nearly 4 GW of new renewable energy capacity in 2013 alone – which is more than two thirds of total 2013 U.S. capacity additions.

Moving an Age-Friendly Washington, DC: Transportation for All Ages

Monday, September 15th, 2014
Density of the DC region’s older adult population (65+)

COALITION FOR SMARTER GROWTH
Baby boomers in DC, who are an estimated 17 percent of the District of Columbia’s population, represent a growing older cohort. Both their presence and well being are important to sustaining vibrant and inclusive neighborhoods. The potential contributions to our neighborhoods by older residents are undermined without forward-thinking planning to address the growing and unique needs of our oldest residents.

Measuring Travel Time at Florida Freeways and Arterials

Friday, September 12th, 2014

FLORIDA DEPARTMENT OF TRANSPORTATION
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.

Illinois Highway Materials Sustainability Efforts

Wednesday, September 10th, 2014
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.

West Valley City, UT: Traffic Modeling of Transit Oriented Development

Tuesday, September 9th, 2014
Figure 2.4 The example of two neighborhoods with different levels of connectivity (Source: New Jersey DOT)

MOUNTAIN-PLAINS CONSORTIUM
Throughout the Wasatch Front Metropolitan Region, the majority of land use development forces people to drive in order to access their destinations. This is due to low density and mostly single use developments built on poorly connected street networks with several cul-de-sacs and few routing options for transport system users. Even though the development of Wasatch Front has the legacy of transit supportive land uses in the region’s city centers and previous street car suburbs, the connection between them is still such that it encourages driving as the dominant mode of transportation. Designing streets and street networks that would support TOD environments is still considered with hesitation as the potential solution for traffic congestion and increasing travel demand. One of the reasons for this might be the need to evaluate the effects that TOD has on traffic operations.

NYC Six Month Report Card: New Class at the City Council

Monday, September 8th, 2014

TRANSPORTATION ALTERNATIVES
In January, 21 new members were sworn into the 51-seat City Council – New York City’s most powerful governing body. Some defeated long-standing incumbents. Many were elected on the strength of their transportation platforms, with promises of more safe, convenient and affordable transportation ushering them into office. In a Transportation Alternatives survey before the election, candidates pledged to improve bus service, expand the bike network and make New York City’s streets and sidewalks safer for everyone. Now, halfway through the first year of their terms, Transportation Alternatives looks back at what City Council members pledged, and how they have lived up to their promises on crucial transportation issues.

Performance of Alternatively Fueled Buses

Friday, September 5th, 2014
Figure 3-2. Comparison of performance and costs of 40-foot buses, diesel vs. hybrid.

NATIONAL CENTER FOR TRANSIT RESEARCH
Florida transit agencies have been dealing with volatile fuel prices and changes in regulations regarding diesel engines and fuel. In addition, emphasis on reducing the overall consumption of fossil fuels has increased, as well as reducing carbon emissions by transit agencies. Florida transit agencies and funding entities continue to be under pressure to reduce operating costs and to run a more sustainable and environmentally friendly fleet in the urban environment. A popular strategy to pursue these goals has been the acquisition of alternatively fueled buses. However, higher reliance on alternative fuels has increased both capital and operating costs for some fixed route operators, and has created challenges for the widespread adoption of advanced transit technologies.

Los Angeles: Eastside Transit Corridor Environmental Impact Study

Thursday, September 4th, 2014
Figure ES-1: Existing and Proposed Regional Metro Rail Lines (2035)

LOS ANGELES COUNTY METROPOLITAN TRANSPORTATION AUTHORITY
In addition to mobility benefits, the Eastside Transit Corridor Phase 2 Project would provide the project area with transportation, economic, land use, and environmental benefits. The analysis presented in this document shows that improved mobility to and from the project area has the potential to boost economic development in the project area and improve social justice by providing better access to employment, educational opportunities, and activity centers. Improved transit connectivity would increase transit ridership, which would also generate environmental benefits through reduced vehicle trips, less roadway congestion, and improved air quality.
