Maren Outwater, PE


Maren Outwater leads the transportation work and is part of the Leadership Team at RSG. She joined RSG in 2010, bringing with her over 25 years of experience developing forecasting models and over 20 years of progressive experience in managing complex model development efforts. She has designed and built forecasting models for activity-based passenger travel, land use, tolling, rail and transit ridership, environmental and economic impacts, and commercial and freight mobility. With a focus on bridging the gap between academic research and practical applications, Maren develops forecasting tools to answer policy questions, to produce performance metrics, and to evaluate innovative transportation investments. She is actively engaged in federal research projects to evaluate autonomous and connected vehicles, improve smart growth and transit, and develop long distance and freight demand models. She is also a registered Professional Engineer in Florida and California.

Maren served, before joining RSG, as the Director of Data Systems and Analysis for the Puget Sound Regional Council (PSRC) in Seattle, Washington. While at the PSRC, she managed a staff of 25 with a biannual budget of $7 million, and led the land use and travel modeling, geographic information, and technology activities of the agency. Her resume also includes management of the West Coast operations of Cambridge Systematics’ travel demand forecasting division.

Maren now lives in San Diego with her family and enjoys kayaking, hiking, biking, tennis, golfing, and cooking.

Maren is a registered Professional Engineer in Florida and California.
