TRB’s National Cooperative Highway Research Program (NCHRP) Report 803: Pedestrian and Bicycle Transportation Along Existing Roads—ActiveTrans Priority Tool Guidebook presents a tool and guidance that may be used to help prioritize improvements to pedestrian and bicycle facilities, either separately or together as part of a “complete streets” evaluation approach.

The guidebook is supplemented by a CD that contains a programmed spreadsheet to facilitate implementation of the ActiveTrans methodology, as well as a final report that documents the research approach, findings, and conclusions.

New Report Finds Drivers Pay Less Than Half the Cost of Roads

As Congress struggles to renew the federal transportation law, a new report from CALPIRG Education Fund and the Frontier Group finds that drivers currently pay less than half the total cost of roads, and argues that while increasing gas taxes could fill the shortfall, it would leave other problems unaddressed.

The new report, “Who Pays for Roads? How the ‘Users Pays’ Myth Gets in the Way of Solutions to America’s Transportation Problems” exposes the widening gap between how Californians think we pay for transportation – through gas taxes and other fees – and how we actually do.

Database improvements for motor vehicle/bicycle crash analysis

Bicycling is healthy but needs to be safer for more to bike. Police crash templates are designed for reporting crashes between motor vehicles, but not between vehicles/bicycles. If written/drawn bicycle-crash-scene details exist, these are not entered into spreadsheets.

To assess which bicycle-crash-scene data might be added to spreadsheets for analysis.

Police crash templates from 50 states were analysed. Reports for 3350 motor vehicle/bicycle crashes (2011) were obtained for the New York City area and 300 cases selected (with drawings and on roads with sharrows, bike lanes, cycle tracks and no bike provisions). Crashes were redrawn and new bicycle-crash-scene details were coded and entered into the existing spreadsheet. The association between severity of injuries and bicycle-crash-scene codes was evaluated using multiple logistic regression.

Police templates only consistently include pedal-cyclist and helmet. Bicycle-crash-scene coded variables for templates could include: 4 bicycle environments, 18 vehicle impact-points (opened-doors and mirrors), 4 bicycle impact-points, motor vehicle/bicycle crash patterns, in/out of the bicycle environment and bike/relevant motor vehicle categories. A test of including these variables suggested that, with bicyclists who had minor injuries as the control group, bicyclists on roads with bike lanes riding outside the lane had lower likelihood of severe injuries (OR, 0.40, 95% CI 0.16 to 0.98) compared with bicyclists riding on roads without bicycle facilities.

Police templates should include additional bicycle-crash-scene codes for entry into spreadsheets. Crash analysis, including with big data, could then be conducted on bicycle environments, motor vehicle potential impact points/doors/mirrors, bicycle potential impact points, motor vehicle characteristics, location and injury.

TRB Special Report 317: The Essential Federal Role in Highway Research and Innovation summarizes conclusions and advice on the Federal Highway Administration’s (FHWA’s) critical role in highway research, development, and technology (RD&T) that have been developed over the years by TRB’s Research and Technology Coordinating Committee (RTCC).

The RTCC is charged to monitor and review the FHWA’s research and technology activities; provide advice to FHWA on the setting of a research agenda and coordination of highway research with states, universities, and other partners; review strategies to accelerate the deployment and adoption of innovation; and identify areas where research may be needed.

The RTCC concludes that FHWA plays an essential role in exploratory, advanced research; addresses national priorities that other highway RD&T programs do not address; and facilitates adoption of innovations at the state and local level through technology transfer.

Along with its other responsibilities, the RTCC notes that FHWA will play a particularly important role with ensuring the standardization of safety alerts to motorists between infrastructure and vehicles as part of the national connected vehicle initiative as well as assisting transportation agencies in implementing the many innovations developed in the second Strategic Highway Research Program (SHRP 2).

Financing U.S. Transportation Infrastructure in the 21st Century

The nation’s transportation infrastructure, it is widely agreed, is eroding and in need of investment. Most policymakers recognize the merits of investing in the system, such as gains in productivity, global competitiveness, and job creation. Low public borrowing rates have also created an attractive climate for increased public investment. However, government leaders have failed to agree on which investments to make and how to pay for them. In order to break this logjam, this paper proposes two tracks of solutions, some of which can be implemented quickly, and others can be executed over the longer term. In the short term, we propose improvement and expansion of the Transportation Infrastructure Finance and Innovation Act lending program, reauthorization of Build America Bonds, better utilization of the Army Corps of Engineers and the Harbor Maintenance Trust Fund, and reform of the federal gas tax. Over the longer term, we recommend investing in research to improve user fee technology and using federal incentives to encourage states to adopt standardized and innovative user fee technology, fostering cooperation in pooled procurement among states and municipalities, and developing and implementing a broad national strategy to guide infrastructure investment in the United States.

Release: Urban sprawl costs US economy more than $1 trillion per year

Urban sprawl costs the American economy more than US$1 trillion annually, according to a new study by the New Climate Economy. These costs include greater spending on infrastructure, public service delivery and transportation. The study finds that Americans living in sprawled communities directly bear an astounding $625 billion in extra costs. In addition, all residents and businesses, regardless of where they are located, bear an extra $400 billion in external costs. Correcting this problem provides an opportunity to increase economic productivity, improve public health and protect the environment. The report identifies specific smarter growth policies that can lead to healthier, safer and wealthier communities in both developed and developing countries.
