-> According to the recently posted Transportation Research Board article, "TRB Annual Meeting Online (AMOnline) portal now includes the papers and presentations from the 2014 TRB 93rd Annual Meeting which includes more than 2,900 technical papers and viewable slides and Posters of the more than 3,600 program presentations from the Annual Meeting. In one search, this portal allows users to quickly find all available papers and visual aids by session, presentation, author, subject area, and more... this site also includes the 2013, 2012, and 2011 Annual Meeting Compendium of Papers... more than 28,000 paper and presentation files are available for viewing and downloading.
"All employees of Year-Round TRB Sponsors, 2014 Annual Meeting Patrons, as well as 2014 Annual Meeting attendee registrants have access to this content in the TRB AMOnline portal at no additional charge..." [Others pay between $10 and $20 per paper or $250 to $500 for the entire collection]
-> According to the abstract of a recently published study entitled Statewide Multimodal Planning, "This paper summarizes the results of a national survey of state departments of transportation (DOTs) focusing on the extent to which they emphasized multimodal solutions in transportation planning. The results offer insights into the size, the scope, and the progress in multimodal planning that states have been making since the passage of the Intermodal Surface Transportation Efficiency Act of 1991. The online survey instrument was distributed to all 50 state DOTs; 35 responses were collected.
"Some key challenges that apparently limited the adoption of multimodal planning approaches in earlier decades are still considered challenges today. The current snapshot of multimodal planning suggests that most state transportation agencies still do not use evaluation criteria to compare multiple modal options. Not surprisingly, constraints and limitations on project eligibility because of funding source restrictions were identified as the major limitation to advances in multimodal planning and program development, followed by the need to follow agency standard operating procedures and by an agency's history and culture of highway-dominated planning. However, changes were clearly taking place. It is a positive sign that many state officials (20 out of 35) concluded that real progress had been made in furthering multimodal planning objectives during the past 10 years."
-> According to a Spring VTPI News article, "‘Preliminary Evaluation of Alternative Methods of Transportation Analysis’ (http://bit.ly/1g7ewii) by the California Governor's Office of Planning and Research, discusses new ways to evaluate urban transportation system performance. This is part of the state’s efforts to develop more comprehensive and multi-modal indicators for transportation project evaluation. This issue is discussed in my Planetizen column, "Change Management: Do Planners Lead or Follow?" (http://bit.ly/1iwHzKF). VTPI submitted comments titled, ‘Beyond Roadway Level-of-Service: Improving Transport System Impact Evaluation’ (http://bit.ly/1i0PemF)."
-> According to a Mar. 10th CalTrans release, "Results from the California Household Travel Survey – the largest and most complex review of its kind – show that the percentage of California residents walking, biking, or using public transportation on a typical day has more than doubled since 2000... Nearly 23 percent of household trips were taken by walking, biking, and public transportation. In 2000, that share was only 11 percent. This increase includes a dramatic increase in walking trips, which nearly doubled from 8.4 percent to 16.6 percent of trips...
"The 2012 study provides a snapshot of the travel behavior of approximately 109,000 persons from more than 42,000 households in 58 California counties, this included parents driving to work or kids biking to school..."
-> According the abstract of a recently published study entitled "Do Residents of Smart Growth Neighborhoods in Los Angeles, California, Travel ‘Smarter’?," "With the individual trip diary from the recent 2009 National Household Travel Survey, a study was done on the effect of neighborhood-level smart growth patterns and socioeconomic diversity on commute mode choice, daily work travel mode choice, and nonwork travel mode choice for individuals living in neighborhoods in the Los Angeles, California, metropolitan statistical area.
"Model results consistently showed that nonauto transportation infrastructure diversity and quality were the most important aspects of smart growth patterns that affected the choice of nonauto travel modes. Moreover, housing mix in a neighborhood increased the likelihood of choosing walking and cycling for daily work trips and daily nonwork trips. The socioeconomic diversity of a neighborhood reduced the likelihood of choosing walking and cycling for daily nonwork trips. The remaining two factors—residential density and mixed use—insignificantly affected travel mode choice. Overall, people living in smart growth neighborhoods in Los Angeles do travel smarter, in that they use environmentally more sustainable (bus and train) and healthier (walking and cycling) travel modes."
-> According the abstract of a recently published study entitled "Causality Between Built Environment and Travel Behavior," "The goal of this study was to explore the causality between the built environment and three transportation modes (private vehicles, mass transit, and nonmotorized modes such as bicycling and walking) while accounting for sociodemographic characteristics for an understanding of what factors may foster transit and nonmotor use.
"Data from the 2009 National Household Transportation Survey combined with Los Angeles County, California, land use data were used to estimate a recursive structural equations model for an examination of causality direction and for a quantification of the built environment effect and residential self-selection effect. Results suggest that urban planning strategies that promote high population and employment density, land use mix, high four-way intersection density, and road density as well as good transit service can either significantly encourage transit use, bicycling, and walking or reduce vehicle miles traveled. However, the relatively small effect of the size of the built environment on travel behavior implies that achieving the above planning goals may cause considerable residential relocation, which contributes to the major part of observed travel behavior changes."
