Demographics Matter - Travel Demands, Opinions and Characteristics Among
Minority Populations - "Race and ethnicity do matter in terms of travel
choices, needs and opinions. many factors contribute to the differences we
see in patterns of travel within population segments. Using data from the US
Census Bureau and the National Household Travel Survey Program, this paper
examines the demographic characteristics of minority populations and the
resulting differences in their travel behavior." Research paper by

Peak Travel in America -
"Understanding peak period vehicle travel is vital for transportation
finance, congestion, and air quality policies...The US transportation system
will face many challenges in the next 20 years: economic and finance, safety
and the aging driving pool, immigration and migration, just to name a
few....Traditional indicators of travel demand may have to be re-analyzed to
ensure that the changing demographic patterns...as peak travel continues to
evolve through the 21st century." Author/presenter: McGuckin, Co-Authors: N,
Contrino, H. and Nakamoto, H., Presented in May 2009 at the Planning
Applications Conference in Houston. It was nominated for the best in the
conference, and re-presented at TRB 2010 in Washington, DC.

An Exploration of the Internet’s Effect on Travel -
"It is clear that the
Internet, like other paradigm-shifting technologies, is going to change
travel behavior as it changes Americans lifestyles...The
relationship between the Internet and travel is complex...We offer up a new
paradigm for describing the effect of the Internet on travel...We contend
that the effect on travel is dependant on the availability and utility of
the Internet applications to accomplish various daily activities.... the
impact of e-commerce on home delivery of goods, and the Internet as a
possible explanation for shifts in time use. Our research shows that we may
be seeing trends in the amount of time spent at home and the miles of travel
by purpose for the cohort of early adopters of Internet use...data from the
National Household Travel Survey (NHTS)...the USPS Household Diary Study (HDS),
Current Population Survey (CPS), and American Time Use Survey (ATUS) are
used....Research paper by

Long Distance Travel - "Overall, about 2.6 billion
long-distance trips are taken by U.S. residents every year. These are trips
of 50 miles or more away from home (100 miles in round-trip distance) for
people of all ages, by all modes of travel, and for any purpose, Many people
never travel that far from home--169 million people (61 percent of the
population) do not make any long distance trips in an average year. In fact,
just 5 percent of the population takes 25 percent of the long distance
trips...." See
NPTS Brief by
McGuckin, N., March 2006.
Mobility and the Melting Pot - "Research confirms that
men and women travel differently. Men make fewer but longer trips, work
farther from home, and when men and women travel together in a vehicle, men
typically drive. Women make more but shorter trips, often doing the business
of daily life—ferrying the kids, shopping, and running errands. Working
women insert these short trips into their commutes, and are more likely to
adopt flex-time and change commute times or routes to avoid congestion.
The amount of difference between men and women’s travel also varies by
race and ethnic origin...."

Travel Trends of the Aging Workforce
- "In a few
years, the first of the baby boom generation (the 76 million of Americans
born between 1946 and 1964) will reach traditional retirement age. The
generation that overflowed schools in their early years and generated a
suburban housing boom in their middle years will possibly change the nature
of travel and commuting as they shift into ‘working retirement’....The
proportion and number of older workers (those over the age of 65) is
expected to increase significantly in the coming decades, and examining this
cohort’s travel behavior may provide insight into this potential future
boom....working patterns of the older population today, to examine their
work trips, and to make some guesses about how the baby boomer generation
will be similar or differ from today’s older population.... commute and
occupational characteristics of older workers in the work force...projected
increase in miles driven by older population groups, trends in labor force
participation, occupations of older workers, overall travel patterns, travel

population." Research by Srinivasan, N., McGuckin, N, and Murakami,

Is Congestion Slowing us Down?
- "The U.S.
transportation system’s quality and pervasiveness are almost transparent to
us as we move between jobs, markets, education, healthcare, and leisure
activities. But the transparency ends when congestion occurs—the system
breaks down as too many vehicles try to move through at the same time.
Congestion reduces mobility and increases auto-operating costs, adds to air
pollution, and causes stress. Congestion is considered one of the major
urban transportation problems. Americans are spending more time to travel
about the same distance in an average day (all trips for all purposes). The
average driver spends over an hour a day behind the wheel, 24 percent more
time than in 1990 ...."

Poverty and Mobility in America -
"The tragedy in New
Orleans after Hurricane Katrina showed how people in poverty are
metaphorically and literally immobilized—stuck in place because of lack of
resources. Although an emergency planner can tell you that there are always
people who stay behind during an evacuation—because they "didn’t hear" the
evacuation warning, or had weathered storms before and thought they could do
it again, or even for the fact that most shelters don’t accept pets, in New
Orleans the number of people who didn’t evacuate was multiplied dramatically
by the city’s high number of people without cars. Over 125,000 people in the
City of New Orleans lived in families where no one had access to a vehicle.
Of course, many of those families were poor, and many poor families are
poorest right before the first of the month when government assistance
checks typically arrive (Katrina hit on the 29 of September). People in
poverty, those without cars, the elderly who live alone, and people with
language or transportation disabilities have special daily travel patterns
and may have special mobility issues. Understanding the needs of the most
vulnerable in our population goes to the heart of the ideal of mobility, and
tests the heart of our nation. Equity in transportation and security binds
the nation together, while inequity divides us...."

"Journey-to-Work Trends in the United States and Its Major Metropolitan
Areas, 1960 – 2000" (Publication no. FHWA-EP-03-058), The
time and means American commuters use to get to work is affected by
demographic and worker characteristics, the supply and location of jobs and
housing, and the time and convenience of various modes of commuting. The
commute trip is so important in understanding people’s daily travel that the
U.S. Census started including questions about commuting in 1960, so with the
2000 Census we have 40 years of decennial data. McGuckin, N. and Srinivasan, N. 2003
Some of the changes that
impact commuting trends are:
▪ Changes in family structure and workforce composition
▪ Growth in area, population, and workers in suburban
counties of major MSAs
▪ Large increases in households with multiple vehicles
▪ Increases in private vehicle use and significant increases in commute times
Hang-ups, Call-backs,
and Incompletes: Non-Response in Telephone Surveys - Telephone
surveys are the standard practice for obtaining data on household travel in
the U.S. But, telephone-based travel surveys seem to be suffering from
declining response rates. This paper looks at a couple of stops along the
continuum of non-response. McGuckin, N., Liss, S. and Keyes, M., submitted
to the 2004 annual meeting of the Transportation Research Board, August
2003,
presented at the
Conference on Transport Survey Quality, South Africa, August 2001.
An Analysis Comparing Households with Interrupted
Phone Service to Those with No Telephone Service - The analysis presented
here compares the characteristics and travel of people with a history of
interrupted telephone service (in the Nationwide Personal Transportation
Survey) to those who have no telephone service at the home in the 1990 Census.
If households with interrupted telephone service can be used to represent
households without any service at all, these two groups should be similar.

Driving to Distractions, Recreational Trips in Private
Vehicles - A large and growing amount of automobile travel is for
recreational purposes. The impact on recreational travel of telecommuting,
teleshopping, and telebanking remains unclear. Historically, enhanced
communication with distant people and information about distant places has
generally led to more travel not less. Mallett, W. J. and McGuckin, N., Transportation Research Record 1719, pp

"Intermodal Truck Traffic: Description and Results of a Survey in Chicago"
"Intermodal Truck Traffic: Description and Results of a Survey
in Chicago" - As part of a growing global economy an increasing portion of
goods from domestic and foreign markets travel through intermodal sites.
Intermodal freight is packaged in containers that are lifted from one carrier
to another (as from truck to rail) or on trailers that piggy-back onto flatbed
rail cars. The location factors, market dynamics, and technological changes
that have shaped and are shaping the intermodal carrier industry are difficult
to forecast. McGuckin, N. and Christopher, E., ITE Journal, pp 38-41 December, 2000. Also see additional

Exploring the Full Continuum of Travel:
Data Fusion By Recursive Partitioning Regression -
This paper describes the need for data fusion in federal statistics and
outlines previous work on data fusion approaches. We detail the recursive
partitioning analyses we perform (CART), and interpret the results. Finally
we address the problem of data fusion using the refined partition, and place
this in the context of statistical methods for record matching.

"Work, Automobility, and Commuting: Differences by Race and Ethnic
Backgrounds"
For many
Americans the car is a comfortable haven as they travel in solitude from
suburban home to suburban workplace. But another picture shows the everyday
commuting experience of families in poverty, in the core of older cities and
older suburbs, who are stuck in low-paid service jobs, without a car, and few
travel options. This group is primarily composed of African-Americans,
Hispanics, and newer immigrants. McGuckin, N., Murakami, E. and Keyes, M.

"A Treatise on Trip Generation"
Trip generation data are either obtained from cordon counts or from
reports of travel from respondents to home interview surveys. It is these two
approaches to problem solution that we will attempt to reconcile in this
review. Why are the ITE trip generation rates different than the rates
obtained from household travel surveys? Does the use of conventional site
impact procedures overstate the traffic impacts of regional shopping centers?
These issues can only be dealt with in a more encompassing analysis of trip
generation rates.
