Census Transportation Planning Package (CTPP) Glossary
Means of Transportation to Work
Means of transportation to work refers to the principal mode of travel or type of conveyance that the worker usually used to get from home to work during the reference week. Data were tabulated for workers 16 years old and over; that is, members of the Armed Forces and civilians who were at work during the reference week. People who used different means of transportation on different days of the week were asked to specify the one they used most often, that is, the greatest number of days. People who used more than one means of transportation to get to work each day were asked to report the one used for the longest distance during the work trip. The means of transportation data for some areas may show workers using modes that are not available in those areas (for example, subway or elevated riders tabulated for a residence area where there actually is no subway or elevated service). This result is largely due to people who worked during the reference week at a location that was different from their usual place of work (such as people away from home on business, working that week in an area where subway service was available). Bus includes bus and trolley bus. Rail includes streetcar, subway, railroad and ferryboat. Other includes bicycle, walked, taxicab, motorcycle, and other.
Travel Time to Work
This question was asked of people who indicated that they worked at some time during the reference week and who reported that they worked outside their home. Travel time to work refers to the total number of minutes that it usually took the person to get from home to work each day during the reference week. Data were tabulated for workers 16 years old and over; that is, members of the Armed Forces and civilians who were at work during the reference week.
