In simple terms, benchmarking is a process of comparing performance and practice among similar organizations as part of an agency’s continuous improvement activities. Benchmarking provides an opportunity to learn about approaches used by high-performing organizations to uncover noteworthy practices, inform target-setting activities, or to foster innovation and improvement within an agency. Benchmarking should focus on improvement and lessons learned rather than as a way to penalize underperformers.

As mentioned in Chapter 1, AASHTO has developed a comparative benchmarking tool for enabling state DOTs to compare performance outcomes and practices with peer agencies as part of their continuous improvement activities (http://benchmarking.tpm-portal.com/). This includes a peer selection tool, so agencies can compare practices to peers with similar characteristics. It also features a performance comparison tool with a number of chart options enabling agencies to compare results. For instance, an agency may elect to compare pavement smoothness characteristics with a neighboring state. There is also a portal to facilitate the exchange of practices among registered DOT users through a Notable Practice Narrative.

An example from the AASHTO TPM Portal showing a comparison of bridge deck percentage determined to be structurally deficient is shown in Figure 6.2. Similar comparisons are available for safety, environmental, and non-motorized (bicycle and pedestrian) performance measures. For transit agencies, Transit Cooperative Research Program (TCRP) Report 141, A Methodology for Performance Measurement and Peer Comparison in the Public Transportation Agency, provides specific guidance for comparing performance with other agencies.
