When applying MOVES (MOtor Vehicle Emission Simulator) in project-level PM (particulate matter) conformity analysis, link-based traffic characteristics are required at local on-road level so as to ensure realistically representation of…
The way one drives has an impact on the instantaneous and total emissions produced for a given trip. Driving style has an impact on microscopic (second by second) vehicle activities…
An efficient and robust surface highway transportation system is essential for continued economic growth of the US. Conversely, vehicle emission has increasingly resulted in adverse impact on air quality and environmental…
Introduction – The medium and heavy duty trucking industry sector could be responsible for 300-400 million metric tons of CO2 by 2030 (World Resource Institute). The same sector currently accounts for…
With the rapid development of new energy passenger vehicles and high speed rail, heavy duty trucks will likely become the major greenhouse gas (GHG) emission contributor in transportation sector. In…
The recent concurrent introduction of models (MOVES2010, CAL3QHCR and AERMOD) and associated guidance new to federally-required project-level “hot-spot” analyses poses significant challenges for state DOTs and other agencies with responsibilities in project implementation.…
Scope: Zero and near-zero emission transportation technologies such as electric and hybrid electric vehicles are critical element in California’s strategy in achieving energy security and in reducing emissions of greenhouse…
Scope: Background: Efforts to develop and deploy clean energy, and transportation technologies that use clean energy (e.g., electric power), are impacted by fluctuating fossil fuel prices. Incentives to deploy clean energy that…
Scope: (1) The objective would be to develop potential regulatory and incentive mechanisms to accelerate deployment of IMO Tier 3 marine vessels to U.S. ports. (2) Key tasks would be…
Scope: Background concentrations representative of a project area are the most critical information needed for transportation projects subject to the new guidance for quantitative hot-spot analyses of particulate matter (PM). The…
