Network methods for project selection based on optimizing environmental impact

Description: "Traditionally, transportation road networks have been designed for minimal congestion. Unfortunately, such approaches do not guarantee minimal vehicle emissions. Given the negative impacts of vehicle pollutants as well as tighter national air quality standards, it is critical for regions to be able to identify capacity modifications to road networks such that vehicle emission are minimal. This ability combined with land use changes and opportunities for non-auto travel are paramount in helping… more
