... The Pontis robot was then run on the MDT Pontis database to create the system metrics and bridge scenario input files. The bridge metrics information was then merged with the pavement metrics information into a single system metrics file.

... Providing visualization of how sensitive different performance measures are to varying investment levels could potentially be quite helpful. They could not be sure how beneficial the tool would be until they actually used it, but they felt that it would be worth giving it a try.

... • On the resource allocation screen, have the network categories, geographic categories, and asset types appear in the same order as they were entered in the configuration. [This comment was later addressed.]

From page 52...
... At the time the testing took place, NYSDOT had developed a prototype of an integrated asset management system that uses a common measure, "excess user costs," for comparing alternative investments and making tradeoffs across different packages of diverse project types. Excess user costs are defined as the incremental costs incurred by users as a result of a facility in less than ideal operating conditions.

From page 53...
... NYSDOT staff suggested the following enhancements: • Add an optimization feature to find the resource allocation across a set of asset types, geographic categories, and network categories that minimizes or maximizes a single designated performance measure (in NYSDOT's case, minimizing excess user costs)

... For example, NYSDOT specified system measures for pavement and bridge preservation projects, but not for safety and mobility projects. For these latter types of projects, NYSDOT would be more likely to specify a performance measure target (e.g., reduction in excess user costs)
