Thursday, Jan. 27 dispatch from the TRB annual meeting in Washington, D.C.:

Not everyone who attends the Transportation Research Board’s annual meeting in Washington, D.C., stays until the end. This year, many who planned to leave before Thurday’s sessions just couldn’t pull themselves away.

Thank the snowstorm.

With fresh snow quickly coating the capital region, flights were canceled and delayed while other traffic came to a standstill. Even the annual meeting’s internal transportation system ground to a halt, as shuttle buses between the three conference hotels stopped running. The Capital Bikeshare program that had served attendees so well on a tour of the district earlier in the week shut down for the weather.

Conference attendees got their exercise walking between hotels, and stopping for snowball fights along the way. Others, with an unplanned night in town, gave more business to District bars.

Along the way, a conference dedicated to the multitude of transportation modes ended up highlighting the original: walking. “Turns out I actually walked 6.3 miles (or more) yesterday,” Richard Moeur, a Phoenix-based traffic engineer, wrote on Twitter. “Need snowshoes!”

Jennifer Dill, OTREC’s director, said the streets in the District’s core were clear by Thursdsay, although the scene Wednesday night was chaotic. “The snow does shut down Washington,” Dill said. “Buses were getting stuck going uphill. There was a big line for taxis.”

Think people who live in suburban developments don't walk and bike? They do, particularly if the development is well-connected. University of Oregon assistant professor Nico Larco has shown this with his OTREC projects.

He explains some of the work himself in this video.

This OTREC educational project took students at Portland State University beyond the lecture hall and the library. Dr. Lynn Weigand expanded the bicycle and pedestrian design curriculum at PSU by turning an existing three-credit course into a five-credit course with an applied lab. The new course gave students the opportunity to apply the knowledge they gained in class to real projects in their community. Working in teams, the students developed projects that focused on improving bicycle and pedestrian connections to the PSU campus. The course received excellent reviews from the students, and the department recognized the courseís value by offering it again the following year. The report can be downloaded at: https://ppms.trec.pdx.edu/media/project_files/OTREC-ED-10-01.pdf.

Professor John Pucher, a car-less commuter from the Bloustein School of Planning and Public Policy at Rutgers University, was the first fall OTREC Visiting Scholar and CTS Seminar guest on September 28, 2007. His presentation, "Promoting Safe Walking and Cycling to Improve Public Health: Lessons from Europe," was standing room only, and the audience enjoyed his photos of bike-friendly features in cities across Europe. Pucher examined a range of public health impacts of our urban transport systems and argued that the current car dependence of American cities is responsible for enormous environmental harm, social isolation, lack of physical activity, and traffic dangers. He described how improving the convenience, safety, and attractiveness of walking and cycling in crucial to overcoming these negative impacts. Pucher discussed specific policies and programs used in Europe, and advocates their widespread adoption in American cities. A lively discussion with faculty, students and members of the Portland Bicycle Master Plan Committee followed the seminar.

Wei Feng: Impacts of Economic, Technological and Operational Factors on the Economic Competitiveness of Electric Commercial Vehicles in Fleet Replacement Decisions

Electric commercial vehicles (ECV) have the potential to substantially reduce greenhouse gas emissions, noise, and pollution in urban areas. In addition, ECVs have lower per-mile operating costs and potentially lower maintenance costs. However, the initial purchase cost of ECVs is significantly higher than the purchase cost of a conventional diesel vehicle. From a purely economic perspective, there is a cost tradeoff between the low operating and maintenance costs of ECVs and their high initial capital costs.  In this paper, a fleet replacement optimization framework is employed to analyze the competitiveness of ECVs. Scenarios with different fleet utilization, fuel efficiency and sensitivity analysis of ten additional factors indicate that ECVs are more cost effective when conventional diesel vehicles’ fuel efficiency is low (8.2 miles/gallon) and daily utilization is more than 54 miles. Breakeven values of some key economic and technological factors that separate the competitiveness between ECVs and conventional diesel vehicles are calculated in all scenarios. For example, in low conventional diesel vehicle fuel efficiency and low daily utilization scenario, ECVs are more competitive when their purchase prices...

Abstract: Walking and bicycling are being promoted as transportation options that can increase the livability and sustainability of communities, but the automobile remains the dominant mode of transportation in all United States metropolitan regions. In order to change travel behavior, researchers and practitioners need a greater understanding of the mode choice decision process, especially for walking and bicycling.

This presentation will summarize dissertation research on factors associated with walking and bicycling for routine travel purposes, such as shopping. More than 1,000 retail pharmacy store customers were surveyed in 20 San Francisco Bay Area shopping districts in fall 2009, and 26 follow-up interviews were conducted in spring and summer 2010. Mixed logit models showed that walking was associated with shorter travel distances, higher population densities, more street tree canopy coverage, and greater enjoyment of walking. Bicycling was associated with shorter travel distances, more bicycle facilities, more bicycle parking, and greater enjoyment of bicycling. Respondents were more likely to drive when they perceived a high risk of crime, but automobile use was discouraged by higher employment densities, smaller parking lots,...
