Workshop on Big Data and Urban Informatics



Big Data has opened up several opportunities to obtain new insights on cities. We invite papers at the intersection of the urban social sciences and the data sciences to be presented in an NSF-sponsored workshop to be held on Aug 11-12, 2014, in the University of Illinois at Chicago, Chicago, Illinois. We hope that the workshop will generate discussions in this emerging area of research, with the goal of long-term community-building on the topic. Travel funds will be available for presenters.

We welcome papers that discuss research results as well as idea pieces of work in progress which highlight research needs and data limitations. Workshop papers will be published in an online workshop proceeding. Selected papers will be published, after additional peer-review, in an edited book.

The objective of the workshop is to bring together researchers with an interest in the use of Big Data for urban analysis. The focus will be on understanding of urban systems, and related examples of urban applications, methods and tools. We are seeking papers that clearly create or use such novel sources of information for urban and regional analysis. Urban and regional analysis spans a broad range of areas. A far from complete list of areas include transportation, environment, public health, land-use, housing, economic development, labor markets, criminal justice, population demographics, urban ecology, energy, community development and public participation.

We invite original research, including position papers, on theoretical developments and applications demonstrating the use of urban Big Data, and the next-generation of Big Data services, tools and technologies for urban informatics. We are interested in papers that use Big Data in one or more of the following five themes:

1)      Theoretical developments and knowledge discovery in urban systems;

2)      Planning and operational uses of urban Big Data;

3)      Urban Big Data measurement, analysis and methodological questions;

4)      Information management for urban informatics;

5)      Institutional issues, organizations, networks and infomediaries in urban Big Data.

Travel funds of up to $700 will be available for a single presenter per paper, on a reimbursement basis. Student presenters will be able to compete for an additional limited pool of funds, for upto an additional $250 per student presenter.

Dates: Extended abstracts of 750-1000 words are due April 1, 2014. Full papers for accepted presenters will be due July 15, 2014.

INSTR 2015 The 6th International Symposium on Transportation Network Reliability

I serve on the International Scientific Committee of INSTR, which is announcing its 2015 conference:

The 6th International Symposium on Transportation Network Reliability

-The Value of Reliability, Robustness and Resilience-

2-3 August 2015, Nara, Japan

The 6th International Symposium on Transportation Network Reliability (INSTR) will be held in Nara, the ancient capital of Japan, from 2-3 August, 2015. The symposium is jointly organised by the Department of Urban Management, Kyoto University, and the Japan Society of Transportation Engineering. The INSTR series is the premier gathering for the world’s leading researchers and professionals interested in transportation network reliability, to discuss both recent research and future directions in this increasingly important field of research.


A special focus of this symposium will be the increasing practical value of reliability improvements for project evaluation. In particular the value of infrastructure investments to improve network resilience to counter large disasters is nowadays a critical issue. Contributions that discuss this issue are specifically encouraged for this symposium though the scope of this conference is wider and includes all aspects of analysis and design to improve network reliability, including;

  •  User perception of unreliability and vulnerability
  • Public policy and reliability of travel times
  • The valuation of reliability
  • The economics of reliability
  • Network reliability modelling and estimation
  • Transportation network robustness and resilience
  • Reliability of public transportation
  • Travel behaviour under uncertainty
  • Risk evaluation and management for transportation networks
  • ITS to improve network reliability
  • Vehicle routing under uncertainty
  • Disaster relief distribution


30 May, 2014 : Submission of extended abstract (1,000 words)
3 September, 2014 : Notification of abstract acceptance
19 December, 2014 : Submission of full papers for peer review
16 March, 2015 : Notification of full paper acceptance
20 May, 2015 : Submission of full, revised papers in camera-ready format


– It is envisaged to arrange special issues in prominent journals with papers drawn from the symposium proceedings. For further details, see

– The 21st International Symposium on Transportation and Traffic Theory (ISTTT21) will be held on the days subsequent to INSTR from 5th to 7th August at Kobe, which is about a 1.5 hours train ride from Nara.

Why must I travel, why can’t I tele-conference

Two times in two days last week I was asked to fly to an east coast city for a half-day meeting. The meeting organizers offered to pay my travel expenses. I asked to save the travel money and tele-conference in via some/any web-based video technology. The organizers declined, saying they weren’t set up to do that.

Seriously, you can pay more than a $1000 to bring me in considering airline tickets, hotel, ground transportation, and meals, but you can’t get your act together to have a room with wireline internet, a camera enabled laptop (aren’t they all now), and Skype or FaceTime or Google Hangouts or any of a hundred other services at a marginal monetary outlay of zero and a time outlay of damn close to that?

I hypothesize one source of the problem is the technological backwardness of the governmental/consulting/advocacy/transportation sector. This is a process of mutual causation. Technological backwardness deters the technologically advanced from entering the sector, reinforcing the backwardness. It’s a wonder there are PCs on people’s desks. It’s no wonder we see no progress. I fully anticipate major changes to the transportation sector to come from outside actors, much like the Google self-driving vehicle because of this innovation aversion.

The second source of the problem might be incentives. I hypothesize the meeting organizers budgeted for travel, and not for information technology. They have no incentive not to spend the budget, the money has to get spent.

The third source of the problem is also incentives. My travel time costs them nothing. My video conferencing takes them a few minutes. No matter their few minutes are a lot less time than my travel, they (not me) are spending it.

I realize video-conferences are not quite as high a resolution in audio or video as being present, and in the hands of the incompetent have meeting-disruptive technical difficulties. But they are good enough for the purposes of this kind of conversation, for which conference calls are often used.

It is not that I object to spending your money, or actually want to save you money. I am not noble in this regard. It is that travel is a major hassle, filled with danger and uncertainty. This is often not worth it for me anymore especially for a less than one-day meeting in a city I have seen plenty of times where

I am doing you a favor by being present (you asked me to attend, not vice versa). Moreover, I don’t want to eat another dinner at an east coast airport.

Update: Bill Lindeke suggests: @trnsprttnst perhaps transportation scholars are inherently biased towards transporting things/people

World Society for Transport and Land Use Research (WSTLUR)

The inaugural World Symposium on Transport and Land Use Research
(WSTLUR) was held in Whistler, BC on July 27-30, featuring over 40
peer reviewed papers (submitted to the Journal of Land Use and
Transport, and keynote addresses from Ed Glaeser (Harvard),
Robert Cervero (UC Berkeley) and David Bannister (Oxford). Please see for the program and links to presentations and even
audio recordings of the keynotes.
The steering committee is now forming the World Society for Transport
and Land Use Research (WSTLUR), who will be charged with organizing a
subsequent symposium in 2014 and other aims of the Society. The
mission statement—broadly, to cultivate an interdisciplinary research
community/agenda— is below.
Members of the society will elect the board (11 seats are open); the
board will then select its officers. (Please see bylaws posted at ; Kevin J. Krizek, University of Colorado, has been
appointed chair of the elections committee). If you are interested in
participating in this exciting international endeavor, we encourage
you to become a member of the society. Attendees of the World Symposium on Transport and Land Use Research
(WSTLUR) are already members.
Fees are $75 for three years
and can be registered by going to .
Elections for the board will commence Sept 15, 2011; if you are
interested in becoming a member and voting in the election, please
become a member by September 9, 2011.
If you or someone you know is interested in serving on the board,
please send a nomination to Kevin J. Krizek ( by
September 9. Anyone can nominate members for the board, however,
nominees must be (or become) a registered member of the society. A nomination
consists of:
-Name of the nominee
-Current position and affiliation
-A narrative (not to exceed 80 words and written in the third person),
describing the nominee’s activities, broadly speaking, in the area of
integrated transport-land use research.
