OTREC-RR-12-01 By Miguel Figliozzi et al.
eBook (PDF): $0.00
The Pacific Northwest and Alaska share interconnected transportation systems. Weather affects these networks, yet climate change impacts are poorly understood. Scientists confirm that climate... More > changes will continue. Diverse topography and local variability complicate efforts to adapt to climate change. High infrastructure costs pressure planners and policy makers to deliver resilient and cost-effective systems. Changing weather impacts all aspects of transportation, yet many practices were developed without considering climate change. For example, more frequent and intense precipitation and floods may lead to failures of roads and bridges designed with old hydrologic data. Such damage may be avoided with current data and design. Socioeconomic changes are likely, but planners are ill-equipped to analyze them. Today’s decisions impact the resiliency of the system as we adapt to climate change. Making well informed decisions now can minimize costly modifications and disruptions.< Less

eBook (PDF): $0.00
This report summarizes the findings of a national project to examine the travel behavior, social capital, health, and lifestyle preferences of residents of neotraditional developments (NTD) compared... More > to more standard suburban developments. We compare survey results from residents of matched pairs of neighborhoods in seventeen U.S. cities and towns, with each pair comprised of one NTD and one typical suburban neighborhood of similar size, age, and socio-demographic composition. The study addresses salient themes in the transportation, planning and health literatures: a national study, surveying populations of diverse incomes, collecting resident information on preferences for and attitudes towards neighborhood qualities, and addressing transportation and health outcomes for diverse community designs.< Less

The Sydney Coordinated Adaptive Traffic System (SCATS) is used to mitigate urban traffic congestion. This research combines SCATS research areas including: a) the relationship between SCATS, traffic... More > volumes, and Transit Signal Priority (TSP); b) between TSP and traffic conditions; and c) the correlation between signal timing and air quality. SCATS showed significant speed improvement at a minor intersection, though major intersection results were mixed. Non-priority signals had a greater impact on travel time than priority signals. A regression model of intersection delays showed major intersections with high cross-street volumes are not likely to experience TSP benefits. Signal timing and queuing have a high impact on pedestrian exposure. Longer green times along the main corridor significantly reduced particulate matter, whereas longer street crossing time increased queuing and exposure. Reduced bus idling time and proper bus shelter orientation are likely to reduce pollution exposure significantly.< Less

This study investigated potential road closure travel disruption due to climate change in two Portland watersheds. We used multiple models to develop an impact assessment method. Runoff was... More > validated for 1988-2006 and used to estimate flood probability for 2020-2049. We surveyed streams at five crossings and found four bridges and roadways below the 100-year flood elevation, leading to frequent floods. Floods will become more frequent under some climate change scenarios. Vehicle miles traveled were not significantly affected by road closure, but vehicle-hours delay increased. Cost analysis is very sensitive to human fatalities or injuries and fairly insensitive to delays. This study presents a comprehensive classification of flood costs, identifies preventative measures, and makes recommendations. Results demonstrate the benefit of integrating top-down and bottom-up approaches in climate change impact assessment, and the need for spatially explicit modeling and participatory planning in flood management.< Less
