This synthesis report presents the use of weigh-in-motion (WIM) data to better design and maintain pavement and bridge assets. The report relies on a survey of state DOTs, a literature review, and five detailed case studies from California, Minnesota, Florida, Maryland, and Tennessee to demonstrate the value in applying this data to asset management.

In this case study, six examples are selected from Maine, Missouri, Montana, Ohio, Utah, and Wyoming demonstrating the connection between asset management and many plans and implementations. The case studies emphasize how asset management supports long range plans, the statewide transportation improvement program, and state planning and programming practices.

In their 2019 transportation asset management plans, many states identified practices for connecting with internal and external partners. This case study presents examples from California, Colorado, Michigan, Nebraska, New Jersey, Ohio, Vermont, and Washington State which demonstrate how coordination with MPOs and local owners of national highways can improve the overall asset management across the state.

This case study examines examples from the 2019 transportation asset management plans, highlighting how asset management provides benefits to the agency. The states included in the analysis are New Jersey, Pennsylvania, Illinois, and Washington State. Their impact includes a documentation of asset management practices and bringing about change in the agency.

While most states still focus solely on their bridge and pavement assets, a handful of states are demonstrating the benefits and best methods for including other assets in their transportation asset management plans. Among these states, California, Connecticut, Minnesota, and Utah are identified for their forward-looking practices. Highlighted in this case study, these state agencies include a whole range of non-traditional assets from signs and ITS to sidewalks and pavement markings.

This case study highlights financial planning practices undertaken by seven states in their 2019 transportation asset management plans. These states connected their asset management objectives with their funding gaps, risks, and investment strategies, and they presented a thoughtful approach for allocating scarce resources. The state agencies include: Kentucky Transportation Cabinet, Michigan DOT, Washington State DOT, New York State DOT, Utah DOT, Vermont Transportation Agency, and Illinois DOT.

This case study highlights examples from the transportation asset management plans of Minnesota, Ohio, New Jersey, and Tennessee. The states in these cases provide excellent examples on how to manage assets through life cycle plans, and they demonstrate how life cycle planning may result in significant savings and improved conditions.

In light of the current COVID-19 crisis, the CPBM System Mobility and Emerging Technology Subcommittee hosted a webinar-style meeting—in place of their usual bi-monthly conference call—to share resources relevant to the COVID-19 pandemic. The meeting began with a roll call and general introduction. After, representatives from FHWA and AASHTO provided updates for their respective organizations in regard to the crisis. Following the FHWA and AASHTO updates, three presentations were given by Rick Schuman (INRIX), Lei Zhang and Michael Pack (University of Maryland), and Monali Shah (Google). The meeting concluded with a discussion about next steps and action items for the subcommittee.

This research and policy guidance focuses attention on ten areas and safety recommendations which will save lives and improve transportation safety. These areas are: distractions, alcohol and drug impairment, shipment of hazardous materials, positive train control, speeding-related crashes, aircraft flight operations, collision avoidance systems, fatigue-related accidents, medical screening for sleep apnea, and strengthening occupant protection. Under each of these categories, the document presents recommendations for aviation, highway, marine, rail, intermodal, and pipeline modes.

This report extends and implements the results of NCHRP Report 806: Cross-Asset Resource Allocation and the Impact on System Performance. Case studies were used to illustrate key issues in implementing a cross-asset resource allocation approach, and the lessons learned were then used to improve the guidance and tools developed in NCHRP Report 806.

This report provides a guideline for identifying right-sizing opportunities where greater social and economic value can be realized by repurposing, reusing, or fundamentally resizing existing transportation system assets.
