UC San Diego LRDP

An extensive VMT analysis was completed for the UC San Diego 2018 Long Range Development Plan (LRDP). VMT calculations were based on the SANDAG Series 13 Regional Model. In addition to using the regional model, GPS data analytics (commonly referred to as “Big Data”) was also used to determine the average trip length for trip-based VMT calculations. The Big Data analysis represented an independent data source from the regional SANDAG forecast model.

Multi-tiered significance criteria and technical methodologies were developed. This approach was critical to ensure conformance to OPR’s guidelines, accurately account for unique travel characteristics and population types of the campus, and disclose any potential impacts.
