In September 2021, ITE released the 11th Edition of the transportation profession's leading source of trip generation information--Trip Generation Manual (TGM). This new edition updates and enhances the 10th Edition by providing the latest multimodal trip generation data for urban, suburban, and rural locations.

An empirical study of five limited-service hotels ("hotels") located in South Florida, USA was performed to measure actual parking demand. This study is based on 35 total field-data-collection observations, seven different observations for each hotel, one for each day of the week, all performed at or near the 1 a.m. peak hour of occupancy for hotel guest rooms (all times are Eastern Standard Time). Following is a summary of key findings and conclusions.

The Trip Generation, 10th Edition Supplement offers significantly expanded multimodal data, including walk, transit, bicycle, and truck data. In addition, new land uses are available (high-cube fulfillment center warehouse, high-cube parcel hub warehouse and affordable housing has been as a new land use).
