| Summary: | Widespread application of traditional performance metrics such as vehicle level of service has resulted in transportation networks that are often suited for only one mode of transportation to the detriment of others. Moreover, the continued investment in capacity expansion intended to meet level of service expectations increases financial burdens on transportation agencies for the capital, operating, and maintenance costs of these facilities, without regard to whether those resources are being used efficiently. Shifting focus to alternative and more comprehensive performance metrics can result in a more economical approach to transportation infrastructure, allowing communities to understand what investment combinations provide the best bang for the buck. Innovative performance metrics also allow communities to consider priorities beyond level of service, and design infrastructure accordingly. The Wasatch Front Central Corridor Study, undertaken in the Salt Lake City metropolitan area, is one example of a regional application of efficiency-focused performance metrics such as person throughput, seat utilization, benefit–cost ratio, access to employment, and economic impacts. Further research opportunities could include development of best practices to standardize benefit–cost analysis for transportation projects, other methods of evaluating overall system efficiency, and the role of parking policy and land use change in maximizing use of transportation resources. |
