The purpose of this project is to test the complete streets LCA framework by using it to quantify the environmental and social impacts of complete streets. The results will be compared with the existing street models that are configured to be vehicle-centric. To test the framework, case studies will be solicited in different parts of the U.S. Advantaged and disadvantaged neighborhoods will be selected for the case studies so that the equity aspects of the framework can also be tested and evaluated. Metrics will be selected to define more and less advantaged communities, such as household income, employment, and access to essential services. Other types of metrics will include transportation/mobility-oriented metrics, metrics from the framework developed in the previous study, such as density of “opportunity destinations,” and ability to access opportunity destinations. The case studies will also include projects in rural areas in addition to urban and suburban areas, and comparison of rural projects with urban/suburban projects will be considered, as well as considerations within both of these types of projects. Case study evaluation will be based on project design for those that have not yet been constructed or completed. Where case study projects have been completed, projects will be evaluated based on the built projects and performance before and after project completion. |
