Abstract This report has been prepared as an information base for people involved in planning, operating, marketing, and decision-making for public transit in America. It characterizes public transit as it is today from a number of perspectives that are believed to be useful to their professional activities. The scale of analysis is limited to the 1995 NPTS, which includes a number of enhancements to the survey content and method and the resulting data base over previous surveys. The most notable enhancements include the addition of questions on public attitudes about transportation, the change from recollection to travel diary for trip recording, and the addition of characteristics for both residential and employment sites. The scale of analysis is also limited to describing various aspects of transit markets, rather than explaining the causality of various relationships observed. The scope of analysis is limited to eight perspectives of characterizing public transit, including: 1) Public attitudes about public transit; 2) Perceived availability and proximity of public transit; 3) Extent of transferring; 4) Perceived characteristics of public transit trips (distance, travel time, speed, and waiting time); 5) Public transit s market shares; 6) Public transit s sub-markets; 7) Propensity for transit use by people who perceive public transit to be available to them; and 8) Public transit s market penetration. Statistics provided on these perspectives complement those from other sources on transit at the national level, such as the decennial censuses from the U.S. Bureau of the Census, the American Housing Survey from the Department of Housing and Urban Development, or the National Transit Data Base from the Federal Transit Administration. 17.

1-1 CHAPTER 1 INTRODUCTION During the past 30 to 40 years, the portion of personal trips carried by public transit has declined in America. Along with other factors, this decline has recently created a strong interest in a better understanding of transit markets, both current and future, in this country. This interest is evident by three recent reports produced for the Transit Cooperative Research Program: Building Transit Ridership: An Exploration of Transit s Market Share (Charles River Associates, 1997), The Public Policies That Influence It and Transit Markets of the Future: The Challenge of Change (Rosenbloom, 1998), and A Handbook: Using Market Segmentation Strategies to Increase Transit Ridership (Northwest Research Group, 1998). The first report examines policies that have some potential for increasing transit s market share and might be pursued by local agencies. The second report identifies potential transit markets that may emerge as a result of expected demographic, socio-economic, and technological changes in the future. The third report provides guidelines to help transit agencies implement market segmentation strategies to better understand their transit sub-markets and increase their ridership. This document has been prepared as an information base for people involved in the planning, operating, marketing, and decision-making of public transit to help them better understand current transit markets in America. It characterizes public transit as it is today from a number of perspectives that are believed to be useful to their professional activities. The characterization of public transit in America is based on an analysis of the Nationwide Personal Transportation Survey (NPTS) data base, which includes information from five surveys conducted in 1969, 1977, 1983, 1990, and 1995. The NPTS data base provides an opportunity to develop current and useful information to aid in public transit planning and analysis. Information from the NPTS data base can help the transit industry hone their understanding of travel behavior and reflect this knowledge in their policy and service planning. While the NPTS data base is a relatively small sample of public transit trips in the nation and inappropriate for service planning in a specific geography, an understanding of travel behavior provides knowledge that can be used to shape the transit industry s understanding of customer needs and behavior. The scale of this analysis is limited to the 1995 NPTS. While it is desirable to have good knowledge on how travel behavior has evolved over time, changes in survey method, especially between the 1995 and earlier surveys, have made direct comparisons across surveys less meaningful. The 1995 NPTS was chosen for this analysis because it is the most recent and it includes a number of enhancements to survey content, survey method, and the resulting data set over previous surveys. The most notable enhancements include the addition of questions on public attitudes about transportation, the change from recollection to travel diary for trip recording, and the addition of characteristics for both residential and employment sites. These enhancements have dramatically improved data quality and enriched the data base for analyzing issues related to public transit in America. The scale of this analysis is also limited to describing transit s trips, users, and markets, rather than determining the causality of various relationships related to public transit markets. The scope of analysis is limited to eight perspectives of public transit, including: C C C C C Public attitudes about public transit; Perceived availability and proximity of public transit; Extent of transferring; Perceived characteristics of public transit trips (distance, travel time, speed, and waiting time); Public transit s market shares;

1-2 C C C Public transit s sub-markets; Propensity for transit use by people who perceive public transit to be available to them; and Public transit s market penetration. The first four perspectives describe public transit markets in terms of its share in the overall travel market, the distribution of public transit trips among groups of its users, the relative level of usage among population groups, and its penetration into the general population. Propensity for transit use measures the relative usage of public transit by a given population group, taking into account the number of persons from this population group who perceive public transit to be available. Equivalently, it measures the per capita use of public transit for a given population group relative to the per capita use of public transit nationwide. Propensity for transit use is calculated by dividing the proportion of public transit trips a given population group makes by the proportion that group represents of all persons who perceive public transit to be available. Public transit s market penetration represents the share of persons in the general population who use public transit during a given period of time. The last four perspectives describe various characteristics of public transit trips and its users. Five types of public attitudes are included: public transit users attitudes about highway performance; public attitudes about public transit in general; public transit users reasons for using public transit for all purposes; people s reasons for not using public transit to travel to work; and public transit users attitudes about the severity of problem areas in using public transit. Availability and proximity of public transit are closely related. In NPTS, availability measures a macro-level of transit being available, while proximity measures a micro-level of transit being available. Specifically, availability gives the proportion of people who perceive public transit to be available in the city or town in which they live, while proximity gives the proportion of people who perceive that their residence is within a quarter mile of the nearest transit stop. The NPTS data base is the only nationwide source that contains information on modal choice for each component of a linked trip. Transferring is examined from two aspects: 1) distribution of linked trips with respect to the number of transfers involved; and 2) percent of unlinked trips that are transfer trips. Five characteristics of public transit trips are examined, including perceived trip distance, travel time (excluding waiting time), waiting time, travel speed (excluding waiting time), and overall speed (including waiting time). While the National Transit Data Base may be used to characterize public transit trips in terms of their length in distance, length in time, and travel speed, this characterization is limited to actual values of these characteristics and is for unlinked trips. It is believed that perception rather than reality drives behavior. These perspectives will be described through the use of statistics at the national level and by population groups, land use characteristics, scale of metropolitan areas, and area density. Information provided in this document complements other data sources at the national level related to public transit in America, such as the decennial censuses from the U.S. Bureau of the Census, the American Housing Survey from the Department of Housing and Urban Development, and the National Transit Data Base from the Federal Transit Administration. Both the decennial censuses and the American Housing Survey focus on commuting trips. The National Transit Data Base provides an important information base on the physical system of public transit, services provided and consumed, and financial characteristics of service provision. This document is presented in five chapters and three appendices. This chapter introduces the topics in the document. Chapter 2 describes the statistical sources used in the study, issues in using the data sources, and the major terms used to aggregate and present data. Chapter 3 places public transit in proper context with trends in demographics, vehicle ownership, and personal travel over the 26 years between 1969 and 1995. Chapter 4 shows the results. The objective is to present findings on public attitudes, transit availability, transit proximity to residents, the extent of transferring, trip characteristics, and market penetration and to summarize the findings on transit market shares, transit sub-markets, and propensity for transit use. Chapter 5 draws implications from the results presented in the report. Appendices A through C provide detailed statistics on transit s market share, sub-markets, and propensity for transit use. The primary objective is to show the influence of the scale and density of areas and transit dependency on transit markets.

2-1 CHAPTER 2 DATA RESOURCES INTRODUCTION Two of the challenges in better understanding public transit are fully understanding the data sources for the statistics presented and the technical language used by analysts in characterizing public transit. The sole data source in this report is the Nationwide Personal Transportation Survey series, which includes five surveys that were conducted in 1969, 1977, 1983, 1990, and 1995, respectively. The main body of this document relies on the 1995 NPTS, which is the focus of the description here. The earlier surveys are briefly discussed in terms of differences between them and the 1995 NPTS. Technical terms include definitions of personal, household, and land use characteristics and geographical areas that are used to assemble and present the statistics. 1995 NPTS The 1995 NPTS is a sample survey of the nation s daily personal travel. It is the only authoritative source of national data on daily trips including, but not limited to: C purpose of the trip (e.g., work, shopping); C means of transportation used (e.g., car, bus); C how long the trip took, i.e., travel time; C time of day the trip took place; and C day of week the trip took place. These data were collected for all trips, all modes, all purposes, all trip lengths, and all areas of the country. The 1995 NPTS was conducted during the period from May 1995 through June 1996. Like all large-scale sample surveys, it involved several stages of data collection (FHWA, 1997a). First, a stratified random sample of telephone numbers were obtained. To control sampling variation and increase coverage of transit trips, the sampling frame was stratified by geography (Census division), metropolitan area size, and the presence of subway or elevated rail systems. Second, the sample of telephone numbers was screened to identify residential households. People living in college dormitories, nursing homes, other medical institutions, prisons, and on military bases were excluded from the sample. Third, an adult member of the household was asked a series of questions about the persons and vehicles of the household. Following this household interview, the household was assigned a travel day for trip reporting. Then, travel diaries for each person 5 years and older were prepared and mailed to the household. Following the household s travel day, interviewers called to conduct the person interview for each eligible household member. A six-day window was established to obtain the travel day data. During the person interviews, travel diary information was recorded in a computer, along with responses to a number of additional questions. The 1995 NPTS response rates are summarized in Table 2-1, which includes the partial response rate obtained at each stage of the survey, and the cumulative response rate up to that stage in the process. Almost 113,000 telephone numbers were sampled initially for household screening. Of these numbers, 73.2 percent were from residential households. Household interviews were completed for 75.6 percent of the residential households. Over 93 percent of the households that completed household interviews accepted the travel diaries, and sufficient person interviews were completed for 72.1 percent of these households to classify them as useable for the 1995 NPTS. Within the useable households, person interviews were completed with 92.2 percent of the eligible persons. The overall response rates were 55.3

2-2 percent for household interviews and 34.3 percent for person interviews. Of the useable households in the final data base, about half of the households are in the base sample and the other half represent the add-on areas of New York State; Commonwealth of Massachusetts; Oklahoma City, Oklahoma; Tulsa, Oklahoma; and Seattle, Washington. Each useable household in the sample was assigned a specific 24-hour Travel Day and a 14-day Travel Period for which detailed data on all travel were collected. Travel days were assigned to all seven days of the week, including holidays. The intent was to represent travel across an entire year. Table 2-1. Response Rates for the 1995 NPTS.

NA means not applicable. Data from the 1995 NPTS are available from the U.S. Department of Transportation in six separate files, four of which are used for this study. These four files include Household File, Person File, Travel Day File, and Segmented File (Table 2-2). The Household File contains data on household demographic, socio-economic, and residence location characteristics for 42,033 households. The Person File contains data on personal and household characteristics, attitudes about transportation, and general travel behavior characteristics such as usual modes of transportation to travel to work for 95,360 persons. The Travel Day File contains trip-based data on trip purposes, modes, trip lengths in terms of time and distance, and trip start times for 409,025 trips. The Segmented File contains data on 3,779 public transit trips that had segments. Segmented trips will be discussed more later in this chapter. Each file has its own weighting variable to expand the sample to provide national estimates in the case of the Household and Person Files, and annualized national estimates in the case of the Travel Day and Segmented Files.

COMPARABILITY WITH EARLIER NPTS SURVEYS The 1995 NPTS data set includes a number of enhancements to earlier NPTS s in survey methodology, survey content, and the resulting data base. The most notable enhancements include the change in survey methodology from recollection to travel diary for trip recording, the addition of a series questions on public

2-3 attitudes about public transit and other components of the U.S. transportation system, and the addition of characteristics for both residential and employment sites into the data base. Table 2-3 shows the additions to survey content and the data base and Table 2-4 shows the changes in survey methodology. The changes in survey methodology make the 1995 NPTS incomparable to earlier ones. When comparing the 1995 and 1990 NPTS data sets directly, there is an increase of about 1.1 trips per person per day, which represents a 35 percent increase. Using selected regional surveys, FHWA s research indicates that one-third of this increase is a real increase in travel, and two-thirds due to changes in survey methods implemented in the 1995 survey (FHWA, 1997b). FHWA, however, has not yet developed adjustment factors for more complicated analysis. For example, it is unclear exactly how the changes in survey methods have affected trip reporting by purpose, travel mode, or other attributes of travel. Since adjustment factors have not been made available for analysis that is more complicated than computing aggregate travel, this study relies predominantly on the 1995 NPTS in characterizing public transit.

ISSUES Introduction Three broad issues affect the analysis of the 1995 NPTS data set and the interpretation of its results: the definition of public transit, the nature of trips collected from the 1995 NPTS, limitations of sample estimates, and sample size. Understanding the nature of trips collected from the 1995 NPTS is critical for understanding public transit trips because transit trips often involve multiple modes and segments. Understanding some of the sampling issues is also critical primarily for understanding the fact that estimates based on a sample will, in general, differ from those based on a census.
