Abstract (Summary)

Several qualitative and quantitative assessment tools have been developed, as a result of increasing interest in environmental assessments of highway projects. These tools, which measure the sustainability of transportation projects or programs throughout their lifecycles, are under development all over the world. With rising societal interest in and understanding of infrastructure projects and their environmental effects, the use of quantitative tools is expected to grow even further.

Few studies have been observed to address this issue so far. The lack of thorough and comprehensive research in this area is problematic, as it prevents project teams from making reliable decisions in the best sustainability assessment tools for a given project. This thesis helps decision makers by introducing and comparing eight different tools for quantitative environmental evaluation of highway projects. In doing so, this thesis evaluates the criteria examined by the eight assessment tools; it conducts a survey with engineers and designers working in the transportation field to identify which of these criteria/credits are most important; and then it provides a multiple comparison statistical analysis on collected data to demonstrate an engineer's perspective of highway sustainability. This study is concluded with determining the main considerations to make highway projects sustainable. These are: reducing public property damage and fatal and serious injuries; preserving enhancing public space, scenic, and natural views to enhance community character of the surrounding area; reducing waste and energy consumption; reducing air pollutant emissions; and designing highway projects to show resilience for future hazards and climate change. A limitation for this thesis was the number of respondents of the survey. The survey distributed among 80 engineers, 50 responds were collected, and 35 highway engineers' responds were used for the analysis.
