NCHRP Synthesis 556 summarizes state DOT practices used to identify pavement and bridge asset locations repeatedly damaged by emergency events and to mitigate the risk of recurring damage in those locations. The synthesis focuses particularly on mitigation practices that concurrently advance TAM and TPM objectives. Information for this synthesis was gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected agencies.

This report develops a collection of transportation agency data management practices and experiences. The report demonstrates how agencies currently access, manage, use, and share data.

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.
