Capacity, demand, and vehicle based emissions reduction strategies are compared for several pollutants employing aggregate US congestion and vehicle fleet condition data. We find that congestion mitigation does not inevitably lead to reduced emissions; the net effect of mitigation depends on the balance of induced travel demand and increased vehicle efficiency that in turn depend on the pollutant, congestion level, and fleet composition. In the long run, capacity-based congestion improvements within certain speed intervals can reasonably be expected to increase emissions of CO2e, CO, and NOx through increased vehicle travel volume. Better opportunities for emissions reductions exist for HC and …

Increased congestion during peak morning and afternoon periods in urban areas is increasing logistics costs. In addition, environmental, social, and political pressures to limit the impacts associated with CO2 emissions are mounting rapidly. A key challenge for transportation agencies and businesses is to improve the efficiency of urban freight and commercial vehicle movements while ensuring environmental quality, livable communities, and economic growth. However, research and policy efforts to analyze and quantify the impacts of congestion and freight public policies on carriers operations and CO2 emissions are hindered by the complexities of vehicle routing problems with time-dependent travel times and the …

TREC Final Reports
Dependence on fossil fuels, climate change, and degraded air quality are forcing the auto industry and consumers to seek alternative solutions to the current transportation system. Significant technical breakthroughs are allowing automakers to develop electric vehicles (EVs) that transcend some of the key barriers that limited them historically. Plug in electric vehicles entered the Oregon marketplace in early 2011. A range of reports suggest the demand for EVs will grow rapidly once affordable highway speed vehicles become available. ODOT identified the lack of a reliable network of electric vehicle service equipment (e.g., charging stations) that increases the range of these …
