The Systems Analysis and Optimization thrust draws on our strength in data-driven decision making and systems modeling and optimization and expertise in renewable energy systems, especially in predictive analytics and optimization algorithms, decision support systems, energy-efficient mobility systems for urban and rural areas. We delve beyond typical metrics like travel time or system throughput. We assess and optimize network resilience, service reliability, operational efficiency, and changes in traffic patterns. We adopt a mixed methods approach to all system analysis. This thrust also provides foundational tools and analysis methods for use in other thrusts.

Quantitatively, we access multi-modal data of various sources at different scales to evaluate various system performance metrics and also perform modeling, simulation, and optimization to design optimal new mobility solutions, including, activity-based models, four-step demand forecasting, mesoscopic dynamic network simulation and microscopic traffic simulation. Qualitatively, we will gather insights on user satisfaction and public perception of efficiency improvements through interviews and surveys, capturing how users perceive and experience these changes.

Modeling and Simulation Testbeds: A Sandbox for Analysis of New Mobility Deployed at Scale

2025-01-14T23:00:27-08:00

In the absence of extensive real-world data on operational strategies and new mobility solutions, including automated vehicles and emerging mobility options, the adoption of modeling and simulation testbeds emerges as a pivotal tool for evaluation at scale. However, while there is a substantial body of research on modeling and simulating new mobility solutions, much of this work remains theoretical and disconnected from the practical needs of practitioners and policymakers. There is a critical need for more applicable, robust, and validated simulation testbeds that can bridge the gap between research and real-world applications. These testbeds should be designed to meet the specific requirements of practitioners and policymakers, enabling them to evaluate new mobility solutions effectively and make informed decisions to improve accessibility, efficiency and sustainability of transportation systems.

Will New Mobility Services Fill Transit Service Gaps? (Phase 1)

2025-01-13T23:02:11-08:00

Transit accessibility remains an issue for many residents, particularly in low-income and minority areas. Additionally, empty buses run during off-peak or late-night hours and in suburban areas to meet coverage requirements, often resulting in inefficient resource allocation. This project will assess the potential for new mobility services (e.g., AVs and micromobility) to fill gaps in transit service and improve operational efficiency.

Optimizing urban mobility: A data-driven approach to strategic Mobility Hub placement

2025-01-13T23:02:12-08:00

Cities desirous of developing a multi-modal mobility platform would need to provide travelers with seamless information about and access to a range of emerging mobility options, such as fixed-route or flex-route public transit, micro-transit, ride-sharing, car rentals, bike-sharing, scooters, moped, and walking routes. Those options altogether have potential to improve accessibility to essential resources regarding employment, health care and food. This research acquires mobility service data to understand travel behavior in choosing mobility options, optimize design of such a platform by optimally placing mobility hubs with multiple mobility options, with the ultimate goals of improving accessibility, sustainability and efficiency for underserved populations.

Scalable V2X Options into the Future: A Los Angeles Case Study

2025-01-13T23:02:12-08:00

Scalable Vehicle-to-Everything (V2X) solutions are essential for enhancing road safety and traffic efficiency in our communities. This project investigates scalable V2X options by considering global advancements and diverse technological ecosystems, utilizing all forms of V2X connectivity—including Cellular V2X (C-V2X), Mobile Edge Computing (MEC), and cellular networks—with Los Angeles serving as a case study. Currently, there's no comprehensive plan to implement these advanced vehicle communication technologies. Our aim is to develop a strategic plan to deploy V2X technology in Los Angeles and Ventura Counties, improving safety, reducing traffic congestion, and preparing for major events like the 2028 Olympic Games. By engaging with various stakeholders and building a practical plan, we hope to create a reference that can inform future deployments by Caltrans or other cities across the U.S.
