Parking Generation - Data Submission


In August 2010 ITE released the 4th edition of Parking Generation, an informational report that provides a comprehensive source of parking demand ratios for land uses and building types.  We are continually seeking the assistance of all parties interested in parking generation throughout the world to assist us in expanding this parking generation resource.  

Data for this publication are being collected continually. To be considered for inclusion a future edition of Parking Generation please submit data to Lisa Fontana Tierney, Planning and Engineering Projects Director, ITE, 1627Eye Street, NW, Suite 600, Washington, DC 20006 USA; fax to +1 202-785-0609 or email lfontana@ite.org.

To assist in the collection of data, two submission forms are available: one for basic sites, the other for complex sites. In addition to sending the completed forms, please send a hard copy of all reports to Lisa Fontana Tierney at ITE Headquarters.

Basic Sites
There are 2 options available for submitting your data:

  1. Complete an Excel spreadsheet on your computer, save the updated file and e-mail it to Lisa Fontana Tierney.
  2. Download an Excel spreadsheet, print the spreadsheet, complete it and send it to the attention of Lisa Fontana Tierney by fax to 202-785-0609 or by mail to 1627 I ("Eye") Street, NW, Suite 600, Washington, DC 20006 USA

Complex Sites
Complex sites are locations where where mixed uses, or where significant shared parking, transit usage, or traffic demand management measures are present. ITE is in the process of developing a submission form for complex sites. For the time being, if you have data to provide for a complex land use, please contact Lisa Fontana Tierney..

Information about the Forms

Definition of Area - One of the variables requested on the data form is the area where the survey is being conducted. There are five choices on the form.

Central Business District (CBD): This would be the downtown area of a city. Characteristics would include very good transit service, street grid, parking garages, extensive pedestrian sidewalk network, multi-story buildings and a wide range of land uses (including mixed use sites). Obvious CBD's would be downtown New York, Chicago or San Francisco. CBD's also exist in smaller cities such as downtown areas of Portland, Maine or Bakersfield, California.

Central City, Not Downtown (CND): This would be the area outside the downtown area of a larger city (typically cities above 250,000 or more in population). These sites typically exhibit greater land use density than suburban sites but are substantially less density than the CBD. The intent of this area designation is for the areas around large central cities such as Seattle, San Francisco, Oakland, Atlanta or Washington, DC - but not large suburban cities which are addressed separately).

Suburban (SUB): Suburban locations are those outside the central city of a metropolitan area. Characteristics would include limited transit services, surface parking, less than complete pedestrian networks, single story buildings and larger groupings of homogeneous land uses. In smaller metropolitan areas (less than 250,000) the area surrounding the CBD could be characterized as suburban.

Suburban Center (SBC): Suburban center areas are those downtown areas of suburbs that have developed CBD characteristics but are not the central city of a metropolitan region. Characteristics can include good transit service, mix of surface and structured parking, connected streets, connected pedestrian network and a mix of land uses. Examples would include the downtown areas of Bellevue, Washington, Las Colinas, Texas or Walnut Creek, California.

Rural (RUR): Areas outside a metropolitan region (any SMSA's) would be considered rural.

Parking Cost - This variable is important to document on each parking occupancy survey form even when there is no charge for parking (place a zero in the data forms). Research has indicated that parking charges impact parking demand. Without this information provided in surveys, parking demand can be misrepresented for a site that has charges for parking as compared to those without parking costs. While the site may not charge for parking - it is equally important to note "zero" parking cost on the form so that the free parking sites can be properly grouped.

If you have any questions, do not hesitate to contact Lisa Fontana Tierney.
