Trip Generation Data Collection in Urban Areas

Assessments of the impact new land use development has on the transportation network often rely on the Institute of Transportation Engineers (ITE) Trip Generation and Parking Generation informational reports. Current ITE rates generally represent travel behavior for separated, single-use developments in low-density suburban areas. However, a more compact urban form, access to transit, and a greater mix of uses are known to generate fewer and shorter vehicle trips (especially in heavily urbanized areas, like Washington, DC). There is both local and national interest in building data that expands upon the existing trip and parking generation rates to include sites located in a diverse, dense context. The objective of this project is to develop multimodal trip generation rates that better reflect the relationship between land use, transportation and travel demand for specific land use types located in heavily urbanized settings, especially in Washington, DC. This includes accounting for how the built environment influences travel behavior, and determining trip rates that reflect the entire activity spectrum of different development/place typologies. These rates must also account for the relationship between parking and trip generation, though this is not the direct focus of this project. The first phase of this project developed trip generation estimates for various land uses where ITE data has been determined to be inadequate and where land development trends illustrate a pattern of demand. The project evaluated the state of the practice, proposed a methodology to collect the data, and conducted an initial data collection to test the methodology. A second phase starting in late 2014 will collect additional data, which is needed to eventually develop a model that can predict trip generation based on the characteristics of a building and its surroundings.
