AI Summary
SCAG seeks proposals for the Scenario Planning Model (SPM) program to support regional transportation and land use planning. The project focuses on advanced travel demand modeling, scenario analysis, and policy evaluation to address emerging trends and uncertainties through 2050 in Southern California.
SCAG has consistently served as the analytical foundation for regional planning, maintaining state-of-the-art modeling practices and tools to support its statutory responsibilities. Its modeling capabilities provide the technical basis for forecasting travel demand, evaluating transportation system performance, and assessing the impacts of land-use and policy strategies on mobility, communities, the economy, and the environment. These advanced models enable rigorous scenario analysis, ensuring that regional strategies align with federal and state performance-based planning requirements and greenhouse gas reduction targets.Within this framework, the Scenario Planning Model (SPM) program supports SCAG’s ability to conduct scenario-based analysis and inform decision-making.1 SPM integrates transportation modeling with land use and policy evaluation, providing a platform for planners to develop and compare alternative growth and investment scenarios. Through interactive tools and performance metrics, SPM helps evaluate outcomes related to travel behavior, including vehicle miles traveled (VMT), sustainability, economy, and health, while contributing to the development of SCAG’s long-range regional plan.Travel demand modeling faces growing uncertainties driven by several factors. Post-pandemic trends, including widespread telecommuting and evolving commute patterns, have altered trip frequency, timing, and distance, while emerging technologies such as electric vehicles (EVs) and other innovations introduce additional complexity in forecasting mode choice and vehicle operating costs. Additionally, California’s zero-emission vehicle (ZEV) mandates and large-scale charging infrastructure investments will reshape fleet composition and travel behavior, creating new uncertainties in route choice, trip timing, and long-distance travel patterns. These dynamics, combined with shifts toward localized travel and changes in peak-period behavior, create significant challenges for accurately predicting future travel demand. The slow decline of population and static employment growth forecasted through the year 2050 for the SCAG region presents additional uncertainties in analyzing future travel behaviors.
