When evaluating transportation projects, there are a multitude of factors to consider. There are standard transportation planning factors, such as the roadway’s functional classification or Level of Service (LOS), as well as factors that measure a roadway’s safety or accessibility to other users. Combining all these variables into a comprehensive framework is a tall order, given the complexity of addressing all these factors in tandem.
The good news is that performance measures that can quantify the positive, sometimes transformative, qualities of complete streets are being employed to evaluate streets. Using a more holistic, multidisciplinary approach evaluation system has several key benefits, chief among them the ability to compare and contrast different projects, which can lead to better designs that promote wider complete streets goals such as economic development, environmental
sustainability, and land use compatibility.

A review of 37 complete streets projects around the country that found that these projects “tended to improve safety for everyone,
increased biking and walking, and showed a mix of increases and decreases in automobile traffic” and “compared to conventional transportation projects,
these projects were remarkably affordable, and were an inexpensive way to achieve transportation goals.”
