Analyzing and Quantifying the Impact of Congestion on LTL Industry Costs and Performance in the Portland Metropolitan Region

Miguel Figliozzi
Christopher Monsere
Recent surveys of Portland based company managers clearly indicates that the manufacturing, service, distribution, retail, and wholesale economic sector are increasingly affected by the growing congestion in the Portland metropolitan region (ERDG, 2005, ERDG, 2007) . Unreliable and increased travel times shrink the distribution radius of existing operations and reduce the operational efficiency of drivers and vehicles. Even though there is a clear consensus regarding the negative impacts o... Read More

Travel Mode Choice Framework Incorporating Realistic Bike and Walk Routes

Joseph Broach
For a number of reasons (congestion, public health, greenhouse gas emissions, energy use, demographic shifts, and community livability to name a few), the importance of walking and bicycling as transportation options will likely continue to increase. Currently, policy interest and infrastructure funding for nonmotorized modes far outstrip our ability to model bike and walk travel. To ensure scarce resources are used efficiently, accurate models sensitive to key policy variables are needed to ... Read More
