Smart Growth Trip-Generation Adjustment Tool

With ongoing input from a technical advisory Panel, UC Davis researchers collected trip-generation data at 30 smart growth land uses in California. They then used this information, along with trip-rates data from other studies, to develop a method embedded in a spreadsheet tool that can be used to adjust available trip-generation rates for “smart growth” land use projects proposed in California.

WARNING:. This tool is only appropriate for sites in smart growth areas, as determined by the criteria on the first worksheet of the spreadsheet. The trip estimates produced by the tool are intended for planning-level analysis at single-use sites or for single land uses that are a part of multi-use sites. The tool does not apply to multi-use developments as a whole. This is version 1.0 of the spreadsheet tool; updated versions may be posted at later dates.
