ITE released the Trip Generation Manual, 10th Edition Supplement in February 2020. The supplement represents the next step in ITE's continued commitment to improve the tools needed
by its members and the general transportation community to understand trip-making in our
communities.
The supplement adds walk, transit, and bicycle trip generation data for 53 land uses.
The numbers of trips by mode are presented in the standard data plot format by time period
and site setting. Modal trip generation is also presented in table form as a percentage of total
person trips by land use.
The supplement adds truck trip generation data for 50 land uses. The numbers of truck
trips are presented in the standard data plot format by time period and site setting. Truck trip
generation is also presented in table form as a percentage of total vehicle trip generation by
land use. The supplement also includes time-of-day distributions for truck trips by land use.
The supplement adds a new land use (Affordable Housing [223]) and substantially expands
data for two land uses (High-Cube Fulfillment Center Warehouse [155] and High-Cube Parcel
Hub Warehouse [156]).
The ITETripGen app has been updated to reflect changes initiated with the supplement.
To make it easier for the analyst to distinguish between plots for different trip types, images
depicting the individual trip types (i.e., walk, transit, bicycle, truck) are included as watermarks
on each data plot. The watermark has been added even for current ITETripGen users who
choose to not upgrade with the supplement.

Modal Trip Generation

The supplement provides data plots that the analyst can use to directly estimate modal trip
generation as a function of an independent variable. Data plots are provided for 53 land uses,
including the key residential, office, and retail uses.
Sample modal trip generation rates are presented in the table below for two land uses for
which multimodal trips should be expected in an urban setting: Multifamily Housing (MidRise) and General Office Building. The data in the table are for the peak hour of adjacent street
traffic and for sites in a Dense Multi-Use
