Conclusions 89 The decision on whether or not to repair these issues is generally made on a case-bycase basis. Regarding ride quality, user complaints, safety concerns, and recommendations from inspectors or inspection data may be used to initiate an investigation to determine if a repair is necessary.

90 Practices for Bridge Approach Systems result of this synthesis, the following areas have been identified as knowledge gaps that could be addressed through future research: • Identification and characterization of correlations between design choices and performance metrics, such as long-term ride quality, for bridge approach systems. The overall goal would be to identify the optimum design configurations for bridge approach systems, which requires a multidisciplinary approach to cover all the components of such systems.
