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

Use of Micro Unmanned Aerial Vehicles for roadside condition assessment

Description: "Micro Unmanned Aerial Vehicles (MUAVs) that are equipped with digital imaging systems and global positioning systems provide a potential opportunity for improving the effectiveness and safety of roadside condition and inventory surveys. This study provides an assessment of the effectiveness of MUAVs as a tool for collecting condition data for roadside infrastructure assets using three field experiments."

Equity evaluation of vehicle miles traveled fees in Texas

Description: "This report used 2009 National Household Travel Survey (NHTS) Texas data to consider the equity impacts surrounding four vehicle miles traveled (VMT) scenarios. Results indicate that all of the VMT fee scenarios are essentially as equally vertically equitable as the current state gas tax system."

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
