The Southern California Association of Governments' (SCAG) Transportation Data Analysis Technical Assistance Program promotes the use of emerging data tools to support data-driven planning across the region. As part of SCAG’s Regional Pilot Initiatives Program, it supports local agencies in accessing advanced mobility datasets and technical guidance to address complex transportation challenges.

SCAG solicited research questions from public agencies and then selected five case studies to demonstrate practical applications of mobility analytics to address transportation safety, congestion, transit performance, demand management, and land use impacts.

These case studies show how big data can complement traditional planning to improve transportation safety, enhance multimodal connectivity, reduce emissions, and support more equitable investments.

While some lessons are specific to the study area and scope of work, several common themes emerged regarding the benefits of big data analytics for mobility planning processes, including more informed decision-making, improved safety and accessibility, stronger support for investments, and increased local capacity.

Case Studies:

• City of Anaheim – Multi-Modal Opportunity Network 
• City of Culver City – Public Accessway Network Analysis 
• City of Pasadena – Corridor Characterization Analysis 
• City of Pomona – Complete Streets Analysis
• San Bernardino CTA – Understanding Commute Patterns to Support Ridesharing
