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

Portable Emission Measurement System-Based Approach to Developing and Evaluating Driving Cycles for Air Quality Assessment

Description: "The first objective is to develop driving cycles for classified roads incorporating both a vehicle's driving activities and its emission characteristics, using the data collected by Portable Emission Measurement System (PEMS), which was neither available nor has ever been used in developing driving cycles. A comprehensive database is established for the collected data and a sophisticated computer program is developed to generate the specific driving cycles. The second objective is to develop a… more

Export growth, energy costs, and sustainable supply chains

Description: "The report examines sustainable supply chains in North America and the role played by rail inter-modal operations in lowering ten-mile fuel and emission costs. It examines whether current systems favor imports over exports - a current complaint from some shippers - and whether the development of inland inter-modal ports offers a solution to moving future freight into and out of large metropolitan areas."

An evaluation of the effects of transit oriented development in a suburban environment

Description: "Transit-Oriented Development (TOD) refers to dense, pedestrian-friendly, livable communities that have good transit as a nucleus. While transit facilities are missing in most suburban towns and the residents are heavily dependent on their vehicles, it is wondered whether residents would take advantage if public facilities were available. This paper presents information about some vital aspects of TOD when viewed in suburban communities."
