The third edition of Shared Parking is a landmark publication and the sole source for estimating, planning and implementing parking across the most diversified use cases for mixed use development. 

First released in 1983 with a second edition printed in 2005, Shared Parking has been an industry-standard book that highlights recommended parking allocations for planners and developers.

The book provides a fundamental grounding in technical guidelines to assist developers of all types in considering the best parking allocations for their development. 

Shared Parking comes in two versions: one version is the book by itself, and the other has a separate Excel calculation tool, which helps developers determine exactly how much parking they need for a wide variety of project types and variables. 


Updates to the third edition include:

  • An expanded number of land use conditions from 20 to 32, along with creating recommended default values for each use that are modernized for time of day and seasonality;
  • Expert opinions and advice on how to determine appropriate assumptions on driving and non-captive adjustments, and
  • An adjusted calculation tool in Excel to account for changes over the past decade that have changed the future of parking space usage. 

The book was written with the support of the NPA Parking Consultants Council (PCC), led by Jerry Marcus, principal, the Parking Advisory Group LLC, and Mary Smith, PE, principal and senior vice president, Walker Consultants, as the lead author. More than 20 engineers, planners and consultants across parking and transportation contributed to the project.
