The Bridge Investment-Performance Nexus at an Aggregate Level – Accounting for Situational and Measurement Biases

In a bid to promote the overall accountability of infrastructure agencies, oversight organizations seek to monitor regularly not only the agency expenditures but also their resulting performance. One context of this expenditure-performance connection is that of infrastructure preservation spending and the physical condition of the infrastructure. This paper presents a refined methodology for examining this relationship. The paper duly recognizes that the integrity of the expenditure-performance relationship could be impaired by situational and measurement biases associated with these attributes, and attempts to correct for these biases. The methodology is demonstrated using aggregate repair expenditures and performance data for interstate highway bridges in the USA. The methodology can help oversight agencies to establish a clearer connection between infrastructure investment and performance, and to carry out an unbiased comparative assessment of infrastructure performance across the jurisdictions under their oversight or supervision.
