Last of the Mohicans has fallen

The last of the mohicans has fallen. My colleague, David Levinson, told me,

“how can you expect to be a self-respecting and authoritative voice on the future of urban transport if you don’t own a smart phone?”

Owing to this and other complications, I just acquired my first cell phone in 43 years. Based on 24 hours of use, I have three semi-philosophical observations:

1. We (as a society) have the lost the art of planning (e.g., where should we meet? It does not matter, I will text you).

2. No one asks for directions anymore; our ability to accurately give them is probably at an all-time low as well (not that it was anything great to begin with).

3. No one talks on the phone anymore, socially. We have seemingly moved to texting for all socially related interpersonal communication when physical proximity jeopardized (and even then texting seems preferred).

VerDuS congress in Rotterdam

I was invited to participate in the VerDuS programme in Rotterdam (the Netherlands) on June 16-17, in which there were a variety of sessions focussing on:

  • Knowledge for Strong Cities
  • Sustainable Accessibility of the Randstad
  • Urban Regions in the Delta

Here are two photos from the event: one from my presentation and another in conversation with Luca Bertolini.


Seminar at ETH Zurich

For those traipsing about in the old continent next week, I will be presenting at ETH Zurich on Tuesday (April 15):

Der Weg des Fahrradverkehrs ins zukünftige

“Paving Bicycling’s Path to Redemption in the Future of Transport Systems”

Where to paint your street |

The last in a 3 part series at rationalizes and prescribes guidelines for where to paint your street.

“Paint is a critical ally as cities aim to spur more innovative bicycle facilities with less. Here’s to unified and clear guidance for applying this valuable resource.”

Call for hosting 2017 WSTLUR

The World Society for Transport and Land Use Research (WSTLUR) invites all interested parties to propose hosting the 2017 World Symposium on Transport and Land Use Research. WSLTUR is an international professional organization that promotes the understanding and analysis of the interdisciplinary interactions of transport and land use, offers a forum for debate, and provides a mechanism for the dissemination of information. The main vehicle for this promotion is the triennial symposium, which aims to bring together the leading researchers in the field to present scholarly papers on the broad set of topics falling within this enterprise. The Journal of Transport and Land Use (JTLU) is the official journal of WSTLUR and will publish select papers from the symposium. More information about WSLTUR and past and current symposia can be found at

The second symposium in this triennial series will be held on June 22-27, 2014 in Delft, the Netherlands, hosted by Delft University of Technology and the University of Twente. We are planning for approximately 140 attendees and 100 paper presentations This follows the inaugural conference held in Whistler, British Columbia, Canada in July of 2013, which was a great success – with 80 participants and 60 paper submissions. For the 2017 symposium, we expect the numbers of attendees and presentations to grow at a modest pace from the 2014 conference.

Entities interested in hosting the conference should submit a full application including the following information:

  1. Name of the city (or town) where the conference will be held. The symposium can be held in remote areas, but a clear transport plan will be needed, regarding how participants will arrive at the conference location.
  2. A brief description about the suggested venue (stating what makes the venue (and/or its near surroundings) an interesting place to visit, seen from the perspective of transport and land use research).
  3. The strengths and profile of the host institution(s) in terms of research within land use and transport field.
  4. A detailed budget, including:
    • Total expected budget for the entire conference,
    • Expected registration fees, and
    • Number of meals included in the registration fees.
  5. Details of tours that the local host can accommodate in the conference city or nearby venues.
  6. Special agreements with local hotels in providing group rates for conference attendees.

WSLTUR will be responsible of all printable materials, conference proceedings, and gifts to attendees. All proposals should be received by email to Ahmed El Geneidy before May 1, 2014, and an announcement will be made regarding the host location during the conference in Delft in June. If you have any questions, please do not hesitate to contact us.

Why paint shines (colored and white ) |

At, I posted the second of a three part series discussing the value of using paint for bicycle facilities and planning.

“City officials make transportation planning decisions under financial duress and scant information. Will rezoning land uses in the neighborhood encourage walking? Will the new bus line decrease car use? Should the city build a protected bike path in the middle of the city? Answers to these questions come slowly as changes in cities take time to mature. People’s travel habits evolve even slower. It is difficult to know what “works” in the transportation business.”

Krista Nordback dissertation defense

The bicycle research community will further benefit from the addition of a great researcher with soon to be “PhD” credentials behind her. Krista Nordback of UC Denver Civil Engineering successfully defended her dissertation, ESTIMATING ANNUAL AVERAGE DAILY BICYCLISTS AND ANALYZING CYCLIST SAFETY IN URBAN AREAS.Picture

Using Boulder, Colorado as a case community (mainly because of the wealth of data available), she created a method to estimate annual average daily bicyclists (AADB) and bicyclist safety at intersections.

Krista employed continuous automated bicycle counts to create a statistical model of bicycle use considering external factors, such as temperature, month, and day of the week. This model allowed her to estimate the average daily volume of bicyclists on a given roadway over a year, analogous to Average Annual Daily Traffic (AADT) for motor vehicles.

Quantifying bicycle use per roadway and path is an important step to assessing which bicycle infrastructure is most used and establishing a baseline for studying other issues such as safety and physical activity.  Specifically, she combined use data with bicycle-related collision data to provide a comprehensive assessment of bicyclist safety by infrastructure type (i.e. bicycle lanes, bicycle paths and shared-roadway bicycle routes) at the community level. Let’s wait for the final, final, final version of the dissertation (20 more days) and then further report on the “elevator pitch” take-away conclusions.

Krista provided a guest blog here last month and is also a member of the Active Communities / Transport (ACT) Research Group.

Congratulations, Krista, on a job well done!
