A Trusted Reference for Forecasting Parking Demand by Land Use

The Parking Generation Manual (PGM), 6th Edition, is ITE’s essential resource for estimating peak parking demand associated with different land uses. Whether you're designing a mixed-use development, revising zoning codes, or conducting a parking impact study, the PGM provides reliable, data-driven insights to support smarter, more sustainable parking strategies.

This flagship manual is a vital companion to the Trip Generation Manual and is widely used across North America by public agencies, consultants, and land development professionals.
