Quantifying the Impact of Truck Only Lanes on Vehicular Emissions on a Limited-Access Highway
<p>This thesis seeks to estimate CO<sub>2</sub> emissions on a portion of the U.S. 101 highway in San Luis Obispo County before and after construction of a truck only lane on the Cuesta Grade. Towards that aim, the microsimulation software, VISSIM, was used in conjunction with the Environmental …

Human Health Impact and Environmental Footprint of Transport Network Generated by Oil Sands In-Situ Thermal Facilities in West-Central Saskatchewan
Greenhouse gas (GHG) and air pollutant emissions are major contributors to global warming and environmental disruption. In Canada, the transportation sector is the leading source of air pollutants and the second largest source of GHGs; a similar pattern is observed in Saskatchewan. In west-central …
