Slide 1: NHTS Early Findings on Public Transportation Travel Trends Steven E. Polzin, PhD., Xuehao Chu, PhD. Center for Urban Transportation Research National Center for Transit Research University of South Florida March 27, 2003 Slide 2: NHTS Enables a Rich Knowledge of Travel Behavior - a Sound Foundation for Policy and Planning Decisions
Slide 3: Outline of Comments
Slide 4: Transit Dependency
Slide 5: Transit Trips and Transit Dependency Trends
Slide 6: Transit Market Share by Car Availability
The pie chart above illustrates transit market share by car availability. 1 car, 1 worker equals 11%, 0 cars and 1 or more workers equals 36%, 0 cars, 0 workers equals 10%, 2+ more workers than autos equals 8%, 1 more worker than autos equals 15%, cars greater than workers 11%,a nd cars equals workers is 9%. Slide 7: Transit Mode Share by Vehicle Availability
Slide 8: Transit Mode Share by Vehicle Ownership
The transit mode share of 0 vehicle households went from 21% in 1995 to 20.5% in 2001. One vehicle households went from 2.4% to 2.5% , and 2+ vehicle households from 0.6 to 0.5. Slide 9: Transit Mode Share by Income
The bar chart above illustrates transit mode share by income level. Under $15,000 had 4.98% in 1995 and 5.32% in 2001. The $15,000 to $50,000 income level had 1.57% in 1995 down to 1.38% in 2001. The $50,000 plus level had 1.07% in 1995, down to 0.91 in 2001. For all (total), the percent in 1995 was 1.81% and 1.57% in 2001. Slide 10: Transit Mode Share by Home Ownership Status
The bar chart above illustrates the transit mode share of home ownership status (i.e. renter or owner). In 1995 Renter transit mode share was 4.57 and by 2001 was only 4.3. For owners, the percent mode share for transit was only 0.9 and declined to 0.7 by 2001. Slide 11: Transit Mode Share and Driver Status
The bar chart above illustrates the transit mode share by driver status by MSA size. For driver and non-driver oustide MSA's, and for MSAs under 250,000, transit mode share was less then 2% (for Driver's less than 1%). For MSAs of 250,000 to 1 million the non drivers increased to almost 5%, whereas drivers in those areas remained well below 1%. In MSAs of 1 million to 3 million, saw non-driver's use of transit grow to almost 10%, and for the 3 million plus MSA even more dramatic to over 16%, whereas driver use of transit in those areas of 3 million or more was only about 2%. The 2001 total show drivers in general use transit only about 1%, but non-drivers use transit over 10%. Slide 12: Who is Using Transit?
Slide 13: Transit Mode Share by Medical Condition
For those with medical conditions in MSAs of less than 3 million, only use Transit less than 3%. Same is true for those with no medical condition. For MSA's of 3 million on more, it is more pronounced, showing those with medical conditions use transit over 6% use transit, and those with no medical condition using transit less than 4%. For all areas, those with medical conditions are about 3% users of transit, and non medical condition at less than 2%. Slide 14: Transit Mode Share by Immigration Status
The bar chart above reflect transit mode share by those born in the United States, and those born outside the United States by MSA size. For MSA's of less than 3 million, those born in the US use transit less than 1%. Those born outside the US for those same areas of less than 3 million use transit more at about 1 to 2 % (almost 3% for MSAs of 1 million to 3 million). For MSA's of 3 million ormore, those born in the US use transit about 3%, and those born outside use transit twice as much at aobut 6%. Slide 15: Mode Share by Frequency of Use
The bar chart above illustrates transit mode share by frequency of use in 1995 and 2001. In 1995, those who took transit two or more time a week came out to 25%, and in 2001 amounted to a little less than 25%. For those who take transit about once a week, 1995 shows about 7% and 2001 below 5%. For those who take transit one or twice a month, both 1995 and 2001 show less than 5%, and for those using transit less than once a month about 1%. Slide 16: Mode Share by Employment Type
The bar chart above reflects mode share by employment type. For "Sales or Service", about 1 1/2 percent, Clerical and administrative support the largest at over 2 percent, Manuafacturing and construction at about 1 1/2, and profession, manergerial or technical about the same. Slide 17: Influence of MSA Scale and Area Density on Transit Market Share (1995)
Slide 18: Ethnicity of Transit Users
Slide 19: Transit Competitiveness
The average speed for income less than $35,000 on commuter bus/train is about 15, for the $35,000 to $64,999 about 22, and for $65,000 plus around 24. For Local bus/streetcar/trolley and heavey rail the average speed was between 7 and 12 miles per hour for the those same income breakouts. Slide 20: Transit Submode Share
The bar chart above shows the percent of transit between the NTD and NHTS data for 1990, 1995, and 2001. NTD Bus for 1991 was 65%, 1995 was 64%, and 2000 was 60%, NTD Rail was 35% for 1991, 36% for 1995, and 40% for 2000. NHTS Bus shows 71% for 1991, 69% for 1995, and 67% for 2000. NHTS Rail shows 29% for 1991, 31% for 1995, and 33% for 2000. Slide 21: Mode Speeds
The bar chart above shows speed by POV and Transit by MSA size. POV's outside an MSA has the greater speed at almost 30 and transit at about 10. For MSAs under 250,000, POV is about 25 and Transit about 10. For MSAs of 250,000 to 500,000 the speed for POV is a littel over 25 and transit a litte over 10. For 500,000 to 3 milllion, POV is about 25 and transit is about 10 for the 500,000 to 1 million. For the over 3 million, POV is about 24 and Transit a little over 10. Slide 22: Weekday Transit Trip Distribution
The line graph above shows weekday transit trip distribution by day of week for 1995 and 2001. Sunday for 1995 showed a little less than 600,000 daily trips, and 2001 showed over 600,000. Monday showed a little over 1,000,000 for both 1995 and 2001. Tuesday showed almost 1,300,000 daily trips in 1995, down to about 900,000 in 2001. Wednesday had roughtly 1,000,000 in 1995, and almost 1,200,000 in 2001. Thursday showed over 1,000,000 trips in 1995, and about 900,000 in 2001. Friday showed a little more than 1,000,000 for 1995 and a little more than 800,000 in 2001. Saturday saw a decrease to about 700,000 trips for 1995 and 2001. Slide 23: Hourly Transit Trip Distribution
Slide 24: Trip Purpose Distribution of Transit Trips
The 1995 and 2001 share of transit trips equated to about 35%. Shopping for 1995 equated to about 11% and 2001 about 13%. School and church about 13% for 1995 and roughly 12% for 2001. Social and recreation amounted to about 12% in 1995 and 10% in 2001. Family and personal saw a bigger change, with almost 15% of transit trips for family/personal, and 10% for 2001. For visiting, roughly 7% in both 1995 and 2001. Medical and Dental saw about 4% for 1995 and 5% in 2001. Other shows only about 1-2% in 1995 but about 4% in 2001. Work related came out with about 2-3% in 1995 and about 4% in 2001. Slide 25: Transit and Elderly
The line graph above shows person trips per day by age grouping. The 85+ age group shows the lowest at 2, and the 35-44 age group shows the highway at almost 5 trips per day.
The line graph above shows percent transit mode share by age group. The 0-14 age group made about 1 trip and increases to over 2 in the 15-34 age groups, and decreased to under 2 trips for the 35-64 age groups. By age 65 and to 74, transit mode trips make up about 1 trip. The 75+ increases slightly to about 1-2 trips.
The pie chart above shows the share of transit trips by age group. The 0-14 age group shows 11%, 15-24 age group 21%, 25-64 age group 61%, and 65+ age group at 7%. Slide 26: Transit Mode Share Trends
Slide 27: Transit Mode Share Trends
The line graph above shows transit ridership trends from the NTD Annual Total and the APTA transit ridership. Transit ridership shows similar curve of annual ridership (unlinked trips) from about 8,000 (NTD) and 9,000 (APTA) in 1990 and declincing down to about 1995 and then increasing steadily upward from 1994/5 to 2002 to a high of about 9,000 to 9,500.
Slide 28: Transit Mode Share Trends
The graph above illustrates the rates of change in VMT and transit ridership from 1990 to 2002 from APTA transit ridership, and VMT (US) and VMT (Urban). The VMT total and VMT urban coorelates closely and increases steaidly to over 30% change from 1990. The APTA Transit Ridership shows greater fluctuation, decline from 1990 to 1995 with about -10 percent change, and then increasing upward to 2001 to about 10% change in 1990.
Line graph above shows transit mode share percent (Urban Vehicle Travel). Data points: 1990 = 2.06%, 1991 = 1.99%, 1992 = 1.86%, 1993 = 1.74%, 1994 = 1.66%, 1995 = 1.62%, 1996 = 1.64%, 1997 = 1.65%, 1998 = 1.71%, 1999 = 1.73%, 2000 = 1.75%, 2001 = 1.75%, and 2002 at 1.70%.
