The Trip Generation Manual is a reference book published by the Institute of Transportation Engineers (ITE) in the USA. It is used by transportation engineers and urban planners to predict the number of trips that a development project (shopping mall, residential building, restaurant, etc.) will generate.

It is the main regulatory and analytical source for:
assessing the transport load of new projects;
modeling intersections and road networks;
developing transportation sections of projects.

The data is based on thousands of real-world field observations across different types of real estate.

The structure of the manual may vary slightly from edition to edition, but usually includes:

Description of the methodology: how the data was collected, observation conditions, definition of key terms (trips, trip ends, rates, equations)
Data sets by type of development (Land Use Codes). Each type is assigned its own code (for example, LUC 210 — single-family homes). For each LUC, the following are provided: average trip generation rates, regression equations for forecasts, data distribution graphs, sample statistics (N, R², standard error), time of day (AM peak, PM peak, daily)
Tables of coefficients (Trip Rates): number of trips per unit of scale of the object (per apartment, per 1,000 ft² of area, per 1 seat, etc.), breakdown into entries and exits, breakdown by day and peak hours.
Descriptions of scale variables (Independent Variables): building area, number of employees, number of apartments, number of seats.
Graphs and regression models – allow predicting trips based on individual project characteristics.
Section on applications and limitations: where and how to use the data, problems with transferring American standards to other countries, recommendations for local calibration.
