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.

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

2025-08-14T17:23:50-07:00

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 varied 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.

Developing a Safety-Centric Framework for the Integration of Autonomous Vehicles in Local Jurisdictions

2025-08-14T17:08:36-07:00

The rapid advancement of autonomous vehicle (AV) technologies presents both unprecedented opportunities and significant safety challenges for local jurisdictions. Recent approvals by the California Public Utilities Commission (CPUC) for companies like Waymo to operate highly automated vehicle services in Los Angeles and San Francisco have ignited substantial public concern over safety and regulatory inconsistencies. This project proposes the development of a safety-centric, risk-based management framework to facilitate the at-scale integration of AVs into existing transportation systems while ensuring public safety is paramount. By engaging stakeholders, analyzing current policies, and collaborating with transportation authorities such as the San Francisco County Transportation Authority (SFCTA), we aim to identify performance metrics, risk tolerance levels, and deployment criteria that decisionmakers may consider. The framework may help local/state agencies understand and implement the good safety management practices for AV integration, balancing innovation with public welfare. Outcomes will include comprehensive policy considerations, refined safety performance metrics, and an enhanced AV safety framework tailorable for local jurisdictions.

Data for Autonomous Transportation Awareness (DATA)

2025-09-04T03:18:40-07:00

AV deployments are rapidly expanding across multiple urban environments, yet current AV operations and planning are often hindered by limited access to standardized, real-time municipal data. Cities produce a wide range of data that could critically inform AV routing and decision-making, including 911 call logs, real-time street closures, construction activities, and emergency response events. However, these data are rarely available in a consistent standardized format suitable for AV consumption. The Data for Autonomous Transportation Awareness (DATA) project aims to close this gap by identifying key municipal data sources, evaluating existing data standards, and developing a scalable, standardized data-sharing framework that can be integrated into AV operational systems. Through stakeholder engagement and data standards analysis, the project will enable AVs to proactively avoid potentially problematic areas (e.g., emergency incidents or active construction zones), thereby reducing conflicts with first responders, improving roadway safety, and optimizing traffic operations. Ultimately, the DATA project will foster replicability, support widespread industry adoption, and ensure that AVs can leverage city data efficiently and consistently, avoiding a fragmented “patchwork” of standards across different regions.

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

2025-09-04T03:33:03-07:00

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.
