workshops description
A substantial part of the conference program is devoted to two series of eight workshops A series: B series: Posters and papers for the poster session are available under contributed papers tab. A1. Surveys for Behavioral Experiments
Workshop Chair: Peter Jones, University College London,
United Kingdom This workshop will address recent experience with, and the special challenges involved in, designing and executing survey research to support the development and evaluation of transportation-related behavioural experiments. Examples include surveys used to support programs such as individualized marketing of travel reduction options and, more generally, conceptual frameworks such as the Theory of Planned Behaviour. Surveys can be designed both to determine the factors that will most influence changes in behaviour, and to estimate the behavioural changes that result from efforts to modify travel patterns. The latter can be before-and-after cross-sectional or more complex panel surveys to estimate change: however, this workshop focuses on consciously experimental frameworks for programme and policy development and refinement, and not on measuring evolving behavioural responses to any change in policy or infrastructure.

A2. Non-response Challenges in GPS-Based Surveys
Workshop Chair: Heather Contrino, Federal Highway
Administration, United States This workshop will focus on innovative techniques for addressing
both unit and item non-response in GPS-based travel surveys.
Designers and implementers of GPS-based travel surveys know
that non-response happens in this context as it does in more
traditional CATI-based surveys. This workshop will provide a
forum for practitioners to exchange information on characteristics
of non-responding persons and households in GPS-based surveys
and techniques for mitigating non-response. Workshop participants
will also share experiences with innovative ways to deal with
item non-response – the failure to obtain complete GPS
information from a participating unit (e.g., someone agrees
to do a GPS survey for 7 days but only uses the device for 2
days). Such techniques include both survey design and post-processing
fixes. Resource paper: Stacey Bricka, Non-Response Challenges in GPS-based SurveysContributed papers:
A3. Electronic Instrument Design: User Interfaces
Workshop Chair: Elaine Murakami, Federal Highway Administration,
United States This workshop will focus on improvements in usability and
usability testing for web-based surveys and mobile phone-based
surveys in both revealed preference and stated response contexts.
Usability refers to the ease of use in terms of the human-computer
interaction -- the clarity, intuitiveness, seamlessness, and
elegance of an application or website interface design. User
interfaces may include maps with look-up capabilities for identifying
specific businesses and locations, satellite imagery like Google
Earth, videos showing real or simulated traffic or new transport
modes, drag-and-drop icons for selecting activities and placing
them into a calendar that can be annotated, among others. This
workshop will discuss usability issues and testing techniques
that have been used in transport surveys as well as ideas from
other fields. Resource paper: Eiji Hato and Harry Timmermans, Electronic Instrument Design and User Interfaces for Activity Based Modeling (+Ann)Contributed papers: 27. Horeni Oliver, Theo A. Arentze, Benedict Dellaert and Harry J.P. Timmermans,
A4. Capturing Travel Behavior Data during Exceptional Events
Workshop Chair: Chester Wilmot, Louisiana State University,
United States The workshop will identify effective survey approaches, sampling
procedures, survey instrument designs and content, and data
collection strategies for capturing personal travel behavior
during unplanned and / or exceptional events. These events represent
conditions when the transportation system is most stressed and
when improvement in its operation would have the greatest beneficial
impact. Such events include emergency evacuation, emergency
response, sudden impacts on transportation systems from external
sources (e.g., extreme weather on air travel, major incidents
on highways, derailment or other incidents on rail systems),
or even unusual demands placed on the transportation system
(e.g., at popular holiday times, Olympic games). Resource paper: Earl J. Baker, Capturing Travel Behavior during Exceptional EventsContributed papers:
A5. Surveys on Urban Freight Transport
Workshop Chair: Arnim Meyburg, Cornell University,
United States This workshop will focus on best practices for the accurate
capture of urban freight movements. It will build upon several
recent surveys that have been carried out in the framework of
European networks, such as COST 355, BESTUFS II, Cityfreight,
Interreg III, Cityport, and MEROPE. These surveys represent
the two main types of urban freight surveys: commodity-based
surveys and tour-based surveys.This workshop will cover the
following points: Diversity of measurement units and methods;
Adequacy of survey content to political and technical needs;
Capacity to analyze the interactions between the agents in the
supply chain, Collection of distribution channels of the supply
chain; Data representativeness, Data transferability; and Use
of new technologies, such as GPS, RFID, for data capture. Resource paper: Danièle Patier and Jean-Louis Routhier, How to Improve the Capture of Urban Goods Movement Data?Contributed papers: 5. Arndt Wulf-Holger,
A6. Moving from Cross-Sectional to Continuous Surveying
Workshop Chair: Dirk Zumkeller, Institute for Transport
Studies, Karlsruhe, Germany This workshop examines the methodological issues involved in
designing, implementing and using data from a continuous measurement
survey. Continuous measurement surveys are longitudinal surveys
that collect data over time. Several types of data may be regarded
as longitudinal: repeated cross-sectionals, representative panels,
cohort panels, and linked panels. Issues that this workshop
will address include: How to cost, Sampling and weighting schemes,
Estimation procedures including producing multi-year estimates,
Non-response and attrition challenges, Dealing with disruptions
in the cycle, and Exploiting panel sample opportunities for
exploring the activity/travel behavior dynamics. Resource paper: Liz Ampt, Sinclair Knight Merz, Juan de Dios Ortuzar and Tony Richardson,Contributed papers: 48. Ruiz Tomás, Harry Timmermans and John W. Polak,
A7. Best Practices in Data Fusion
Workshop Chair: John Polak, Imperial College London,
United Kingdom This workshop forum presents best practices in data fusion.
Transportation policy and planning studies require data on travel
behavior are often obtained from travel activity surveys. In
the 40-year span since the early 1960’s, when systematic
surveying of travelers has begun, response rates for travel
surveys have dropped significantly. At the same time, the cost
of conducting such surveys has skyrocketed. One of the avenues
of considerable promise includes supplementing the survey data
by integrating with readily available data from other compatible
sources. In this context, the term data fusion refers to the
process in which two or more databases are integrated so as
to obtain necessary parameters or a single database. In this
workshop the challenges and opportunities related to data fusion
concerning travel survey and other related databases are examined
to produce best practices. Resource paper: Caroline Bayart, Patrick Bonnel and Catherine Morency, Survey Mode Integration and Data Fusion: Methods and challengesContributed papers: 42. Nakamya Juliet, Elke Moons and Geert Wets,
A8. Understanding Relationships among Transportation Infrastructu
re, Physical Activity and Health
Workshop
Chair: Kelly Clifton, University of Maryland, United States
This workshop will focus on recent survey designs and methods, uses of technology in surveys, and other innovative measurement techniques for better understanding the many relationships between people’s physical activity, the role of physical activity in personal travel behavior, and the constraining or stimulating impact of infrastructure and urban form. This topic is important because societies around the world are concerned with the fast-growing incidence of obesity and obesity-related diseases. Walking, biking and other non-motorized modes of travel represent a potentially successful antidote against obesity. Incidence of these travel behaviors is related to access to physical activity venues and expanded opportunities for engaging in physical activity so the measuring and analyzing the relationships among these variables is an important contemporary issue.

B1. Data for Public Transit Planning, Marketing and Model Development
Workshop Chair: Orlando Strambi, Escola Politecnicada
Universidade de Sao Paulo, Brazil This workshop focuses on innovative and efficient methods for
sampling passengers, collecting data, analyzing travel patterns,
and using administrative data for transit planning and marketing
and travel demand model development. Many public transit systems
have grown into multi-modal systems that include bus, shuttle,
light rail, commuter rail, car-sharing, and para-transit services.
Transit agencies are interested in collecting empirical data
about their systems – Who uses it? How people use it?
When they use it? How might usage be improved, enhanced, or
in some cases impaired? How to segment or visualize transit
markets? These questions require collection of attitude, opinion,
preference, and behavior data from users and non-users of the
public transit system. Some of this data may be captured through
surveys; other data may be administrative or ITS data. Resource paper:

B2. Vehicle-Based Surveys
Workshop Chair: Klaas van Zyl, Stewart Scott International,
South Africa This workshop will raise methodological challenges in vehicle-based
surveys and ways of overcoming them. Usually individuals (or
households) are surveyed for passenger transport and firms for
freight. However, to address research and policy questions on
environmental issues and energy consumption, vehicles are also
significant sampling units. Research questions concerning such
surveys include: Do exhaustive sampling frames exist and for
what scope (private cars, light or heavy trucks)? Is it necessary
and / or sufficient to survey vehicles through the households
or firms which use them? What information can be obtained by
combining administrative data with survey data? How to get multiday
and multiperiod information for a dynamic analysis? What information
could be provided by automatic data transmission from the vehicle?
How new technologies (e.g. data-logger, GPS) can improve the
accuracy of data collected? Resource paper: Jean-Loup Madre and Dominica Kalinowska, Vehicle-Based Surveys: toward more Accurate and Reliable Data Collection MethodsContributed papers:
B3. Evolving Behaviour in the Context of Interest in Environmental
Sustainability
Workshop Chair: Mark Bradley, Consultant, United States This workshop is concerned with survey methods used to understand
the evolution of individual and household activity/travel patterns
and underlying decision-processes. A focus is the creative use
of mixed data collection methods (e.g., retrospective, revealed
behaviour and stated response methods) to provide observations
of past, present and potential patterns, and especially in support
of sustainability policy. The need for this type of survey package
has increased as policymakers need to evaluate environmentally-relevant
responses of travellers to a wide variety of hypothetical changes,
including improvements in transport/communications technologies,
the introduction of user-oriented policies such as congestion
pricing, or shifts in the housing market. One key theme is using
the data and findings from modest samples, such those used in
as activity scheduling surveys, to lever data from larger samples,
such as time-use or travel surveys. Another is the particular
challenges of meeting the data needs of models of future behaviour
in socially-charged contexts, including achieving representative
samples and avoiding social norm response bias. Resource paper: Peter Bonsall, What is so special about surveys designed to investigate the sustainability of travel behaviour?Contributed papers: 6. Behrens Roger and Romano Del Mistro,
B4. The Collection and Processing of Survey Data using Mobile
Technologies
Workshop Chair: Jean Wolf, GeoStats, United States This workshop will develop advice that could be given to practitioners
about what is currently feasible and reliable in the areas of
collecting and processing travel data using mobile technologies,
such as GPS, GNSS, RFID, cellular phone hand-offs, and multi-sensor
platforms. Person- and vehicle-based survey methods incorporating
increasingly miniaturized and affordable electronic technologies
are developing rapidly and diversifying. Trends include primarily
passive observation over relatively long periods involving minimal
contact with respondents, and more highly interactive approaches
involving rich interfaces with respondents, notably web-based,
to validate summaries of observations and expand the variable
set. All packages depend on sophisticated computerized processing
methods, with or without linkages to GIS data: the conception
of such packages by survey designers will be an important component
of the workshop. Resource paper: Peter Stopher, Collecting and Processing Data from Mobile TechnologiesContributed papers: 8. Bohte Wendy and Kees Maat,
B5. Data Visualization Techniques
Workshop Chair: Michael Manore, Consultant, United
States This workshop will provide a venue for sharing innovative data
visualization techniques for travel survey data. By improving
visualization methods, transport researchers and practitioners
can convey to policy makers the richness and the insights of
data. We are searching for innovative, information-rich, as
well as beautiful graphs, charts, maps and animated visualizations.
They can be the results of data mining tools or statistical
analysis addressing either microdata (individual records) or
aggregate data. Interactive tools usable by policy makers or
citizens are of special interest. Making the data "come
alive" is crucial for discussion and stakeholder participation.
The workshop will focus on the definition and solution of the
visualization problems involved rather than the technical work
behind the data itself. Resource paper: Catherine Lawson, Visualize This: Opportunities and Challenges for the Travel Survey CommunityContributed papers: 12. Chapleau Robert, Catherine Morency and Marlène Bourgeois,
B6. The Acquisition of Long Distance Freight Data
Workshop Chair: Kara Kockelman, University of Texas
at Austin, United States This workshop will focus on how to improve the acquisition
of long-distance freight data. Long distance is defined as 500+
kilometers (about 300+ miles). Data on long distance freight
transport can “acquired” by management sources (for
rail, waterborne transport, etc.) or by surveys (e.g., Commodity
Flow Surveys, surveys on freight vehicles harmonized by EUROSTAT).
Challenging issues are: How to capture information on the multiple
“trips” of the transport chain that might include
more than one mode of transportation; Opportunities and barriers
provided by data acquisition technologies (e.g., RFID); How
to optimize the sample scheme to collect information on alternatives
to truck-only chains; How and when to combine survey data with
administrative records; How to capture data on vehicles and
loading factors for the measurement of energy consumption and
GHG emissions; among others. Resource paper: Alan McKinnon and Jacques Leonardi, The Collection of Long Distance Road Freight Data in EuropeContributed papers: 7. Horst Hermann Binnenbruck,
B7. Surveying “Hard to Reach” Groups
Workshop Chair: Roger Behrens, University of Cape
Town, South Africa This workshop will discuss recent advances in methods for ensuring
the participation of hard-to-reach groups in transport surveys.
The adequate inclusion of so-called “hard to reach”
groups - including participants with limited national language
or literacy skills, ethnic minorities, adolescents and physically
challenged - in transport surveys has become increasingly significant
over the last decades for policy and planning purposes. Issues
that will form the subject of discussion are rare population
sampling techniques, non-probability sampling approaches, different
motivational approaches for encouraging participation, good
practices for structuring surveys; and approaches for testing
the appropriateness of survey materials, including cognitive
research. These issues will be discussed in the context of different
international settings. Resource paper: Benoit Riandey and Martine Quaglia, Surveying hard to reach groupsContributed papers: 40. Contrino Heather, Nancy McGuckin, Yuki Nakamoto and Adella Santos,
B8. Surveys of Tourists and Transients in Urban Areas
Workshop Chair: Alan Pisarski, Consultant, United
States The workshop will examine how to measure the impact of tourists
and transients (temporary residents such as business people,
out-of-town shoppers, or other visitors) on travel in urban
areas, including the nature, timing, and location of travel
within an urban area. The travel behavior of these people is
likely to be quite different from that of regular residents
meaning that the whole approach to the survey will probably
need to be reconfigured for this purpose. The workshop will
identify different groups of tourists/transients in terms of
their expected travel behavior, and how they could be sampled,
recruited, and surveyed. The workshop will also consider how
the data from tourists/transients could be combined with regular
travel data to obtain a more complete picture of travel in an
urban area. Resource paper: Christophe Terrier, Tourist flows and inflows: on measuring instruments and the geomathematics of flowsContributed papers: 11. Borgers Aloys, Chang-Hyeon Joh, Astrid Kemperman, Shigeyuki Kurose, Dick Saarloos, Junyi Zhang, Wei Zhu, and Harry Timmermans, |
