Women on bikes

From the League of American Bicyclists:

In our latest Women Bike report, “Women on a Roll,” we can see how important these two elements are to bridging the gender gap in bicycling. Yesterday, we took a closer look at “comfort” and “convenience,” hosting a webinar with two expert researchers in the field: Jennifer Dill of Portland State University and Susan Handyof University of California, Davis.

Their research on women’s attitudes toward bicycling provided great insight for the report, and we were able to delve more deeply into their findings. We learned more about the bike facilities women tend to flock to, why women tend to have less of a positive attitude toward bicycling, and the strategies to help make bicycling more comfortable for everyone.

World Symposium on Transport and Land Use Research 2014

Call for Papers (note subsection below on active transport)

World Symposium on Transport and Land Use Research 2014

June 24-27, 2014 in Delft, the Netherlands

About the Symposium

We are pleased to announce the 2014 meeting of the World Symposium on Transport and Land Use Research (WSTLUR) to be held in Delft, the Netherlands, June 24 – June 27, 2014. The conference provides a unique international forum for academics and practitioners at the intersection of economics, planning, design, engineering, and other relevant disciplines. The Conference is aimed at developing a better understanding of the interaction between the dynamics of land use and transport, with an emphasis on the way in which the built environment can contribute to more sustainable transport in a rapidly changing world. Papers are welcome on a wide range of topics covering all modes of transport, both passenger and freight transport, at all spatial scales.

The Delft University of Technology hosts this conference in the bicycle friendly city of Delft in the heart of the Randstad Holland. In addition to the technical program, the conference provides a day tour through parts of the Randstad, including transit-oriented development in the city of The Hague’. Hotel rooms are pre-booked in the historical city center; within walking distance of the university campus (public transport is also available).

In addition to presentations based on peer-reviewed papers, the conference program will include confirmed plenary presentations from:

  • Glenn Lyons (Professor of Transport and Society, University of the West of England, and founding Director of the Centre for Transport and Society);
  • Patricia Mokhtarian (Professor of Civil and Environmental Engineering at the Georgia Institute of Technology effective August 1, 2013); and
  • Bert van Wee (Professor in Transport Policy ,Delft University of Technology, faculty Technology, Policy and Management).

Submission of Papers

WSTLUR seeks papers on the interaction of transport and land use. Welcome domains include: engineering, planning, modeling, behavior, economics, geography, regional science, sociology, psychology, health, architecture and design, network science, and complex systems.

Original papers must be submitted electronically November 30, 2013 for consideration. Full papers should be uploaded for peer review at http://jtlu.org prior to midnight (Pacific Standard Time) in the above mentioned date. See http://wstlur.org for more details related to the conference.

All papers accepted for WSTLUR will be considered for publication in the Journal of Transport and Land Use.

WSTLUR welcomes all papers on the topic of transport and land use. In addition to this general call, special calls are listed below in alphabetical order.

  1. Accessibility Analysis and Evaluation, led by Karst Geurs (k.t.geurs@utwente.nl; University of Twente) and Ahmed El-Geneidy (ahmed.elgeneidy@mcgill.ca; McGill University). This is a special session on accessibility modeling and analysis organized by NECTAR (Network on European Communications and Transport Activities Research) Cluster 6 and WSTLUR. Although accessibility analysis has evolved from simple calculations to complex and detailed methods at fine levels of spatial resolution, there are many outstanding questions on accessibility analysis and modelling – and its practical use in transport planning. We particularly welcome papers on the use of accessibility measures in impact evaluations of transport investments, e.g. economic and social impact assessments, also in the light of network vulnerability and resilience issues.
  2. Active Transport and Land use: led by Kevin J. Krizek (krizek@colorado.edu; University of Colorado Boulder). Ideal papers for this special issue will explore detailed aspects of non-motorized travel and its interface with existing transport networks and urban form, policy, or other relevant dimensions of travel behavior or health. Selected papers from this session will be included in a special issue of JTLU. See the WSTLUR paper submission web page for detailed instructions.
  3. Children and Youth Transport and Land Use Theory, Method and Applications: Led by Ron Buliung (ron.buliung@utoronto.ca; University of Toronto) and Raktim Mitra (raktim.mitra@ryerson.ca; Ryerson Univeristy).. A broad call for papers intended to draw attention to the connection between children and youth mobility and land use/ built environment. We invite international research focused on theory, innovative survey methods and applied research.
  4. Empirical Studies of Automobile Parking and Travel: led by Dan Chatman (dgc@berkeley.edu; University of California, Berkeley): The strong influence of the supply and cost of automobile parking on automobile use is both intuitive and theoretically well-established. But there have been fewer empirical studies of how on-street and off-street automobile parking affect auto use or the use of other travel modes. A related issue is whether built environment characteristics like density, diversity, and design have been ascribed influences upon travel that are actually due to variations in the supply and cost of parking, Ideal papers for this special issue will address any aspect of parking supply as a built environment characteristic and its empirical relationship to travel patterns, or novel theoretical relationships that have not already been established in previous literature.
  5. Integrated Land Use and Transport Models: led by Zachary Patterson (zachary.patterson@concordia.ca; Concordia University, Montreal). The past two decades has seen the development and application of increasingly advanced integrated transport and land-use modeling systems. Papers on the application of these models into emerging areas (e.g. social equity), innovations in submodels of these complex modeling systems and their incorporation in the planning process are welcomed.
  6. Network Structure: led by David Levinson (levin031@umn.edu; University of Minnesota), Stephen Marshall (s.marshall@ucl.ac.uk; University College London), Kay Axhausen (axhausen@ivt.baug.ethz.ch; ETH Zurich), and Basil Vitins (basil.vitins@ivt.baug.ethz.ch; ETH, Zurich). The structure of transport networks depends on, and shapes both demand for travel and patterns of land use. Empirical and theoretical analyses of rules or grammars for generating networks and places, systematic characterization of networks, studies of the development and evolution of networks, comparative network analysis, and the relationship between network structure, land use, and travel behavior are welcome.
  7. Transit Oriented Development (TOD): led by Kees Maat (C.Maat@tudelft.nl TU Delft). TOD principles have been developed in metropolitan areas, in order to promote more sustainable travel behaviour. Papers providing empirical evidence and discussing implementation and governance issues are welcomed.

When submitting your manuscript please verify which session stream you are interested in.

Citi Bike Launches In NYC, But Will It Reach New Yorkers Who Aren’t Rich And White?

NYC is again showing its colors: Based on the expansive coverage the CITI bikesharing program is getting in the NYTimes and other outlets, one would think there aren’t 30 other cities in North America with systems already. (Ok, fine, no other system has 300 stations with 6,000 bikes).

Together with David Levinson and David King, I am interviewed by Roxanne Palmer in the International Business Times for the article, Citi Bike Launches In NYC, But Will It Reach New Yorkers Who Aren’t Rich And White?.

My “insights” include:

“The bicycle is so affordable, at first blush you’d think it’d have a widespread appeal to the economically disadvantaged,” University of Colorado Professor of Planning, Design and Civil Engineering Kevin Krizek told International Business Times. “But at least in this country, the preponderance of people riding tend to be male, 40ish, and relatively well-to-do. So if you kind of translate that forward, the people using bike share tend to fall into that same demographic profile.”

Bikes “are not a status symbol yet,” Krizek says. “We’ve had a car culture for so long.”

“All things with respect to NYC versus any other U.S. city in terms of transport tend not to be comparable,” Krizek says. For instance, “car culture is, by several standard deviations, considerably less in NYC.”

“A lot of other cities have put out the bikes first and are now saying, ‘We need better infrastructure,’” Krizek says.

“It’s still uncertain whether bike-share programs in the U.S. are viable transportation options for most residents, or a way for cities to provide “another kind of luxury item,” Krizek says.

Sensing a common theme: “can’t we get along?”

Rodney King’s quote might continue to live on. I am sensing a common new theme this spring centered around education and other efforts to encourage bicycles and cars to “get along.” This theme certainly comports with my developing theory of the importance of autos and cars being able to better “co-mingle” in downtown (and other environments). See: (1) the New York bike sharing folks are holding classes to help educate cyclists about riding with cars around and (2) the creative Bikes Belong video of the month, encouraging the modes to “roll together.”


Active Communities / Transport (ACT) Research Group Scholarly Workshop

The Active Communities / Transport (ACT) Research Group (co-directed by Kevin J. Krizek) will be hosting its first “Scholarly Workshop;” April 18-19 on the Boulder/Denver campuses. Daniel Rodriguez, PhD, of UNC-Chapel Hill will be the first distinguished scholar. The workshop is intended to provide insights and feedback on research currently being pursued or proposed by student and faculty members. All members of the CU community are welcome to attend with complimentary registration.

Please consult the schedule and book of abstracts.

Current ACT students will present their well-developed research proposals to ACT faculty and student members, as well as to Dr. Rodriguez, and receive feedback from the group. The central purpose of the event is to learn from close interactions with a proven scholar, and to elevate the quality and depth of the group’s work through constructive and critical feedback. In addition, there will be opportunity to reflect on perspectives and experiences about transportation-land use research and scholarship. Please email with questions or further interest. If you would like to attend or for further information, please contact Professor Krizek.

Pedestrians and cyclists can get hurt even on NYC sidewalks, but the heavier ones less so

The NY Times reports on an article re: pedestrian and cyclist safety from the Journal of Trauma and Acute Care Surgery.

-Gathering data from 1,400 people who have been injured is impressive.

-That pedestrians are most vulnerable in crosswalks is not surprising; it is where the pedestrians are–the whole “exposure” aspect.

But now, we finally have a partial silver lining to the obesity epidemic in the US: excessive weight may prove a boon for pedestrians in a collision. Victims with an above-normal body mass index were found to have less severe injuries than their counterparts. “It is not implausible that a greater proportion of torso and extremity fat may protect against injury”

Infographics and gamification

The following infographic from Active Living Research recently came across my email. It is nicely presented; it is a fair representation of some of the research.  But……

…while it might satisfy some central purposes of an infographic, we have argued elsewhere, it is best to to consider the balance of the research and not rely on what one study here or there has to offer about a particular factoid.

Illustration of points for completing sustainable activitiesThe larger issue is that based on an article in the recent issue of ensia, knowledge and information have little to do with behavior change. Moral suasion does not work either (my favorite quote from the article: “If educating people about an issue would solve the problem, we would have no obesity and no smokers in our country”).

Two reactions: First, competition (what they call “gamification”) and peer pressure are paramount. We are getting there with the both–in terms of cycling, at least–but these elements take time to engender in society. Second, talk is cheap. Most everyone says they want to save water and the planet; action is less so.


Cyclists defensive about the pollution they emit

Cyclists recently came out in hoards to repel the comments from the Washington State politician who claimed, “Since CO2 is deemed to be a greenhouse gas and a pollutant, bicyclists are actually polluting when they ride.” Both the Seattle times and Velonews picked it up. And, the politician has since apologized.

It reminds me of the GM ad telling college students to stop pedaling and to start driving–an ad that was met with so much opposition that it was pulled by GM back in the fall of 2011.

** And just fyi, here are two “journalistic reporting stats” that appeared in the Seattle Times report: (1) On average, cars emit about three-quarters of a pound of carbon dioxide per mile, while bicycling releases just over 1 ounce per mile, including manufacturing, according to analysis by the European Cyclists Federation. and (2) food calories burned by a rider may well be equivalent to 650 miles per gallon, figures Todd Litman, of the Victoria Transport Policy Institute.

Three-hundred and twenty-nine days in NYC

329 days is how much longer the Bloomberg administration will be in office in NYC, including Janette Sadik-Khan. So, this how long they have to finish all of their aggressive cycling projects for which they have received much acclaim and this is how long we have to wait to hear the degree to which the new incumbent might roll back some of the advancements.
