Washington D.C.
Mr. Chairman, Distinguished members of the Committee, ladies and gentlemen, my name is Alan E. Pisarski, and I am honored to be invited to speak before you once again to address the outlook for American travel. I recall with pleasure that I participated in your hearings in 1997 in the advent to TEA-21, and also in the first hearing for ISTEA. It is a responsibility that I take very seriously.
I recall in that first hearing that Senator Moynihan spoke of seeing the New York World’s Fair in 1937 as a youngster and how it affected his sense of the future of transportation. I related then that I had been there also, my parents had wheeled me thru that fair as a newborn, and I must have acquired some of the same flavor he did.
We need to look at the next reauthorization period through the lens of the changes likely to occur between now and the end of the cycle. As the next reauthorized period concludes, delivering us to the doorstep of the year 2010, we will have seen dramatic changes in the first decade of the new century:
– We will have crossed 300 million in population at some point midway in the period
– Our rural population alone will be over 60 million, more than many nations
– We will have added more than 25 million people
– And perhaps as many cars as people
– Another 10 million households
– More than 10 million more immigrants
– The first of the baby boomers will be at retirement age.
– 13% of the population will be over 65 years of age
– We will have added four trillion dollars or so to our economy
In many respects our world and the transportation system that serves it will be a different place.
In reviewing travel trends and their social and economic determinants I like to use the following list of eight elements of transportation. Now more than ever it is critical to keep them in mind.
1. •COMMUTING
2. •OTHER LOCAL TRAVEL
3.
•TOURISM
4.
•SERVICE VEHICLES
5.
•PUBLIC VEHICLES
6. •URBAN GOODS MOVEMENT
7. •THRU PASSENGER TRAVEL
•THRU FREIGHT TRAVEL
Too often we say we are going to talk about transportation and then we forget freight and talk only about passenger travel; then we say we will talk about passenger travel and end up talking about metropolitan commuting. Then we get into an argument about highways versus transit and get lost in the thickets of advocacy.
We must consider both freight and passenger travel, in both their metropolitan and non-metropolitan forms as the list indicates. Many of our issues of the future will be centered in freight-passenger conflicts; and intercity-local interactions.
The Metaphor of the Wilson Bridge
One of the difficult problems addressed by the Congress in the recent past has been the Wilson Bridge. It is the perfect symbol of our challenges:
– It is a critical commuter corridor in the morning and evening
– A major all day regional connector for passengers and freight
– A major route for buses and private vehicles from Maine to Florida
– A critical freight link in the I-95 corridor – main street of the Northeast
It is an aging, heavily-used facility suffering from both functional and physical deficiencies operating in a complex inter-governmental environment. There are many Wilson bridges in our future.
My focus today will be on taking the long view on the nation’s travel activity trends and demographic future and its implications for future travel.
First a report on where we are with respect to commuting and other travel trends. I made the mistake of going back and reviewing my testimony five years ago and some of the thoughts I expressed then have been borne out, others need some modifying in the light of the new census data.
The changes between 1990 and preliminary 2000 data from the statistics of the Census Bureau are shown in the accompanying table.

The extraordinary fact continues to be that in the nineties, as in the eighties, the increase in the number of single occupant vehicle users was greater than the increase in total workers. In effect all new commuters went to the SOV and additional commuters switched from carpooling, walking etc. The significant difference is that transit did actually gain in numbers of commuters in the nineties, though at a rate less than the growth rate for workers overall thus reducing its overall share, but a positive trend nonetheless.
Some may see cause for disappointment in that transit shares have not increased. There are reasons to be somewhat more sanguine. Transit served about 4% of the new commuters, less than its traditional overall share of 5%, but its gain of about a half million users certainly is a far superior performance than its actual decline of several hundred thousand in the 1980-1990 period. If we can say that the decline of transit has been arrested we will have accomplished a great deal. When the final census data are available it could show gains for transit sufficient to hold share at 5%. Transit reports show gains since the census was conducted. The more important share questions for transit are in metropolitan areas rather than national figures.
Few nations have been challenged by what Australians have labeled “the tyranny of distance” as greatly as America, and fewer still have reduced its influence on their economic future as we have. We have succeeded through a combination of timely investments in infrastructure and benign public policies that served to permit market forces to work in very positive ways. We have been blessed with great potential endowments and have responded well to those endowments. In the eighteenth century transportation knitted together a nation; in the nineteenth century it welded together great internal mass markets; and the twentieth has seen us integrate our nation into the world economy helping to define and support that world economy.
Transportation is all about reducing the time and cost penalties of distance on economic and social interactions. To the extent that nations succeed in that function they enable tremendous forces of economic opportunity, social cohesion and national unity.
– LOWER POPULATION GROWTH
– LOWER HOUSEHOLD GROWTH
– LOWER LABOR FORCE GROWTH
– SATURATION OF DRIVER’S LICENSES
SATURATION OF CAR OWNERSHIP
LOWER DOMESTIC MIGRATION RATES
There are many facets to the challenges raised by our aging society. A sharp image is portrayed in the graphic below showing the crucial role played by the aging of the baby boom. The combinations of that boom with greater health among the older population and declining birth rates will sharply shift the relationships between our population groups.
Present estimates place the population over 65 at about 35 million, only
slightly increased from 1990. The small increase was a product of limited
increase among the depression babies generation, those now between 65 and 75,
but we also saw extraordinary growth in those between 75 and 85, rising
23%. There are roughly 70 men for each
100 women in the group. Persons over 65 composed 12.4% of the population with
29 states with equal or higher percentages.
By the end of the coming cycle of reauthorization those over 65 will rise to 13.2% by 2010 and reach 20% by 2030 as the last of the baby boomer surge reaches 65. At that point we will have reached a stage where there will be more than 31 older citizens per 100 working age adults contrasted to about 20 today. During this period the working age population is actually projected to decline by 5%. At the same time the dependent young will remain about the same level. As a result the number and kinds of trips made by and for the elder population will increase sharply. By 2025 there will be 27 states with 20 percent of their population over 65 or more, higher than Florida today.
A number of factors will have bearing on how that population will meet its travel needs:
Stagnating Labor Force
The chart above that showed the growth in the older population also showed the diminishing growth in worker-age groups. The graphic provides both the history and the future of American age and labor force relationships. From the 70’s on we see the sharp rise of the working age population as baby boomers joined the labor force age group, compounded further by women joining the labor force in extraordinary numbers, doubling the labor force by 2010. But as 2010 approaches, the size of the labor force age group stops growing and remains effectively constant out into the future. Some projections have indicated that the group actually slightly declines in numbers. The implications of this for retirement programs have been discussed extensively in the public press around the world. In fact the US is less extreme than many western nations in this regard.
The working age population responding to those job developments will be sharply changed from the past. While the entire working age population is projected to grow by about 12% the number of members of the labor force over 55 years of age will grow by almost 47%. Workers over 55 will be responsible for half of the growth in labor force from 2000 to 2010. Although these changes need to be of concern we should note that the average age of the labor force in 2010 will be about the same as in the sixties just as the baby-boomers began to join the labor force.
From a transportation view, however, an additional and perhaps more significant factor will be shortages of workers, particularly in skilled jobs, which may lead to important potential changes in travel behavior, such as:
If the last decade was one of too many commuters the next may be the decade of too few. There will be a severe lack of skilled workers in the future – apparent already. We will have to employ everyone who is employable. Transportation will be central to making that happen. Connecting rural populations and inner city residents to suburban job centers will be one need. The great demand for workers means that workers will be more free to choose where they wish to live and employers will follow. This may mean greater dispersion of jobs and home sites, but it need not; workers may opt for center city living as well as rural life styles. It will mean an amenity-driven development process where areas that can attract and retain workers will be highly advantaged.
Much of this suggests greater freedom for workers to define the when and where of their work. It will mean more flexible work hours for older workers and parents. Jobs in the future will be flexible in a more humanized work place – women in the work force have seen to that. The jobs of the future will look to us from this vantage point like part-time jobs. The implications for travel are a more dispersed and balanced travel pattern throughout the day.
Changing Household Composition
The number of households increased by almost 14 millions between 1990 and 2000, growing faster than population, yielding smaller average household sizes. Households are key generators of travel – more so often than individuals. Had households remained at their 1960 levels we would have 20 million fewer households today. Households have declined to less than 2.6 persons in size, and family-based households are down to 3.14.
Households without children have grown more rapidly than those with children. In 1970 40% of all households were those of married couples with children, today they account for less than 25% of households. They are now outnumbered by married couples without children.
A notable facet of our future is that we have more than 33 million non-family households, about a third of all households, more than 27 million of which consist of persons living alone. We now have 10 million persons over 65 living alone, most of them women. Their transportation needs are likely to be significantly different than the general population.
America is once again a nation of immigrants as it was at the start of the last
century, as shown graphically below – however the extent to which that is true
is unclear. Census estimates have
ranged from 8 to 11 million immigrants arriving in the 1990’s with some
estimates reaching as high as 14 millions.
This would place immigration somewhere around 40% of the sources of
population growth in the nineties and an even greater share of the labor force
age group. Of the roughly 28 million
foreign born in the US today 40% arrived between 1990 and 2000.
From a transportation view it must be noted that additions to the population by natural increase generate a new worker in 18 or so years; whereas immigrants, heavily distributed in the working age years, are often instantaneous additions to the work force and the traveling population. Of those immigrants arriving between 1990 and 2000 the census estimates that two-thirds are in the age group from 16 to 45, and more than 80% of men and 50% of women are presently in the labor force.
The flow of immigrants nationally is toward the South and West; tending to locate where other Americans are, in the largest metro areas, where the jobs are. Although they have been a significant factor in replacing residents who have been leaving center cities, the current immigrant wave is far more likely to arrive directly at suburban locations contrasted to center cities as in past migrations.
Mainstreaming Minorities – the Democratization of Mobility
Many of the aspects of the questions regarding immigrant
travel behavior are interrelated with a discussion of the travel behavior of
racial and ethnic minorities. For
example, their arrivals in the many large metro areas of the south and west
actually had the effect of reversing declining trends in the number of
households without vehicles. Not
surprisingly there are indications that new immigrants use transit more than
current residents, but that over time their travel choices echo the general
population. Immigrants constitute a significant element of transit ridership
today in many metropolitan areas. A
distinct role for the transit systems of the nation may well be in the
socialization process of immigrant populations.
It is often the case that immigrants and resident minorities constitute that group in our society with limited mobility. Their growing access to vehicles will be one of the major factors in travel growth in the future. The figure below shows the long term trend in vehicle ownership among households. The key observations here are that one vehicle households having been stable for almost 40 years at about 30 million households have jumped by 5 million in the last decade, and a related move of households without vehicles to below 10 million for the first time. Both of these moves are strongly related to immigrant and minority trends. We have moved from more than 25% of households without vehicles in 1960 to less than 10% today even with the surge in immigrants in the last decade.
The relative saturation in drivers’ licenses and vehicles has been noted earlier. These apparent national patterns mask the reality that such saturation has a long way to go before it is a fact among minorities and immigrants. While the White Non-Hispanic population tends to be saturated in ownership of drivers licenses, with both men and women having above 92% with licenses, these values are more like 80% among Hispanic and African American men and in the range of 70% among women of those groups.
Auto ownership has similar patterns with households without vehicles at about 7% among White Non-Hispanics and closer to 30% for African-American households and half that for Hispanic households. Even rural African-American households have 17% of households without vehicles.
An important facet of national mobility regarding minorities is the longevity of the vehicle fleet and the resultant affordability of serviceable vehicles for lower income households. The average age of the vehicle fleet today exceeds 8 years.
In many respects our minority populations are somewhere back in the sixties or seventies in terms of transportation and mobility
– They are at 25% of households without vehicles, as the general population was in 1960
– Minority women are at 70% with drivers licenses; white women probably were at that level in the 60’s.
– Long distance travel rates by minorities are less than the general population rates of the seventies.
Rising Affluence and Aspirations
Perhaps the most illuminating variation in transportation spending is that between rural populations and their urban counterparts. Rural households have the highest share of income going to transportation expenditures (23.5%) contrasted to only 19% for urban residents. In fact they spend more in total dollars, about $7460 than their urban counterparts despite earnings about 80% of urban households. It is tremendously significant, however, that rural residents have the lowest housing costs share and have the lowest total costs share for the housing-transportation combination. Housing and transportation are tightly linked in cost and character with transportation representing the trade-off in terms of home cost and size. The fact that two-thirds of American households own their own homes is a crucial factor in our understanding of transportation budgets.
At 2000 with about 1.72 vehicles per household, on average, the majority of American households have two
or more private vehicles; vehicles available equal or exceed workers in the
majority of households regardless of the number of workers in the
household. Perhaps the most significant
event in auto ownership, as noted earlier has been that households without
vehicles have dropped below 10% of all households for the first time.
– A STABLE “OLDER” POPULATION
– OPERATING IN A GLOBAL ECONOMY
– WHERE “HIGH COST” TRANSPORT IS OK
– WHERE SKILLED WORKERS ARE AT A PREMIUM
– WHERE MANY WORKERS CAN LIVE AND WORK ANYWHERE
– WHO, WHERE ARE THE IMMIGRANTS WILL BE A KEY
QUESTION
– WHERE MAINSTREAMING MINORITIES WILL BE A KEY
FACTOR OF GROWTH
We will be a
challenge affluent society where transportation will have immense importance in
helping us remain competitive and to realize our economic and social
aspirations.
To me transportation is
about society building – not just economy building – society building ! It ties people together across distances –
especially today when families are dispersed over the entire nation.
The greatest strength of our economy is the nationwide mobility of workers in a highly specialized division of labor. Transportation knits families back together.
Many planners still think
in terms of “community” as the people physically next door – our communities
today are a product of multiple voluntary links across vast distances supported
by two pillars –communications and transportation – virtual communities.
Transportation’s goals are all about speed, cost and reliability and those are the three things we are just terrible at measuring in transportation! We must do better.
In summary the factors that will matter most in the
future are these:
For commuting – the lack of workers, skilled workers especially, creating a sellers market in jobs – greater freedom of location through technology and greater flexibility about work schedules (more part-time-like jobs) in the work place. Who and where the immigrants are will be central. Expect appeals to older workers and even more women to join the work force.
For Local travel – an aging population with more freedom and discretionary resources for recreation and other travel. A more mobile minority and immigrant population. A generally more affluent society able to act on its social and economic interests. Expect very active daytime, evening and weekend travel patterns.
For Long Distance Travel – many people in the peak long distance travel age
groups; more people able to participate in long distance travel; more foreign
visitors. Expect a peak period in American tourism.
For Geography – the flows between local elements of the nation will expand faster than the internal travel within those elements. Expect interaction conflicts between long distance and local travel.
A higher value of time for people and goods means greater emphasis on time-saving technologies and modes of transportation for both. Expect interaction conflicts between freight and passenger travel.
