This project investigated the impact of varying two elements of pavement, bridge, and mobility asset management on the longterm network-level performance of those assets. The first element was the condition at which restorative treatments are triggered. The second element was the budget available to implement these treatments. The feasibility of examining the network-level performance impact of changing safety enhancement treatments trigger values was limited, and therefore the project did not investigate those impacts. For each of the pavement, bridge, and mobility assets, three different management strategies in the form of treatment trigger values were investigated: a standard treatment trigger strategy, an early treatment trigger strategy, and a late treatment trigger strategy. For pavement and bridge assets, the standard treatment trigger strategy simulates INDOT's current treatment trigger policy. The early treatment trigger strategy simulates performing treatment at a better condition level than the standard treatment trigger strategy, while the late treatment trigger strategy simulates deferring treatment to a worse condition level than the standard treatment trigger strategy. |
