In the August 2014 issue of the ITE Journal, Jeffrey Tumlin, Eric Dumbaugh, and Wesley Marshall explore the error of assuming transportation performance measures are objective. They are not. The authors assert “we should be aware of how our performance measures relate to the values and desires of the public which we serve. If there... Read more »
BART Board member Gail Murray, Joey Goldman, Cathleen Sullivan, Bethany Whitaker, and other colleagues led a study that has been released from the Transportation Research Board. Under TCRP Project H-49, they identified and documented the motivations, benefits, and barriers to coordination and integration among multiple public transportation providers. The Transit Integration Manual (Volume I) provides... Read more »
RB’s National Cooperative Highway Research Program (NCHRP) Report 832: State DOTs Connecting Specialized Transportation Users and Rides, Volume 2: Toolkit for State DOTs and Others assists agencies and organizations with the process of designing, developing, implementing, and evaluating linkages that connect customers of specialized transportation services and programs with rides. The stand-alone toolkit directs lead agencies and partners through the decision process for their state, region, or county, and factors in budget limitations. Design decisions and evaluation criteria tailored to each functionality level are also provided.
In an era of limited and constrained funding, transportation agencies struggle to meet the needs of travelers and the demands on the system. Agencies need creative and low-cost transportation solutions and seek to identify ways to maximize use of existing multimodal networks.
As I learned of the health implications and realized my role in specifying these chemicals into projects I was trying to make healthier, I searched for ways to avoid using them.

A compilation of data on substances in the built environment that may cause or aggravate asthma, a disease of high and increasing prevalence and major economic importance. This is a valuable resource for identifying asthma triggers and asthmagens, minimizing their use in building materials and furnishings, and contributing to our larger goals of fostering healthier built environments.
PVC is unique within the broad spectrum of plastics because it is a chlorinated plastic. Its chlorinated chemistry is responsible for a range of environmental and human health hazards.
Many flame retardants are persistent, bioaccumulative, and/or toxic, and the building products that incorporate them can be avoided in many cases.
