The objective of this research was to develop a guidebook and tool prototype that senior DOT managers may use to analyze and communicate the likely system performance impact of investment decisions across multiple types of transportation assets. The guidebook includes a framework incorporating (a) the several dimensions of system performance important to stakeholders (such as mobility, safety, and community livability); (b) the multiple measures an agency uses to describe condition and service of particular classes of transportation-system assets (such as pavements, signals, and drainage structures); and (c) the targets that an agency may set for the various dimensions of performance.
The framework and tool prototype were developed under NCHRP Project 08-91 to reflect both technical best practices and transportation agency organizational and institutional needs.
