The 5th Edition of the ITE Parking Generation Manual (PGM) represents a significant improvement in the content and capabilities from previous editions with more than 60 percent new data, additional analysis capabilities (e.g., urban setting, day of the week variations, seasonal variations), consistency with the recently updated Trip Generation Manual, 10th Edition, time of day distributions and parking supply ratios for the majority of land uses, and a web-based app that enables the analyst access to the full database for specialized analysis.
The PGM contains text, tables, data plots, and statistics that describe current state-of- the-practice understanding of the relationship between parking demand and the many characteristics associated with an individual development site or land use. The manual presents land use descriptions and data plots for all combinations of available land uses, time periods, independent variables, and settings contained in the ITE database. The intended use of PGM is to forecast parking demand at a specific development site by time of day on a specific day of the week.
The manual is available in both hardcopy form and as an electronic file. The publication is supplemented by ITEParkGen, a desktop web-based application that allows electronic access to the entire ITE parking generation dataset. The web-based app enables an analyst to reproduce the data plots and statistics presented in the manual. The web app also provides numerous filtering capabilities for the analyst to view subsets of the complete database. Subsets can be created according to the geographic location of the study site, the age of the parking demand count, and the development size.
