This synthesis documents how state DOTs manage Mechanically Stabilized Earth (MSE) walls in their inventories, including practices for maintenance, rehabilitation, assessment, and life-cycle cost analysis. While MSE walls are common in transportation projects for their efficiency and resilience, most are too new to evaluate long-term performance, and design standards have evolved significantly over time.

Advancements in connected and automated vehicle (CAV) technologies present new challenges for Traffic Incident Management (TIM) and emergency responders (ERs), particularly due to limited information sharing among stakeholders. NCHRP Research Report 1104 offers essential resources and communication tools to enhance collaboration and understanding between CAV developers, TIM personnel, and ERs. The report equips responders and those in the TIM community with strategies and insights to effectively engage with the evolving CAV landscape.

NCHRP Research Report 1121 distills practical tools, methods, and guidelines that help transportation agencies modernize data integration, sharing, and management for planning and traffic operations. Grounded in real-world use cases—integrated corridor management, smart-city initiatives, incident response, performance management, work-zone oversight, and more—the report captures best practices and lessons learned while showcasing proof-of-concept products that tackle persistent obstacles such as incompatible data standards, data-quality gaps, and concerns over proprietary or sensitive information. Deployment assistance examples illustrate how well-designed data architectures foster collaboration among public agencies, private partners, travelers, and connected devices, leading to more informed, data-driven decisions. A companion website hosted by the National Operations Center of Excellence (https://data.transportationops.org) compiles the full set of best practices and supplemental resources.
