Background

My research area bridges between transportation and environmental analysis; and my main expertise is in modelling of road transport emissions and urban air quality as well as evaluating population exposure to air pollution. I am interested in capturing the interactions between the daily activities and travel patterns of urban dwellers and the generation and dispersion of traffic emissions in urban environments. I lead an active research group focusing on modelling traffic emissions and near-road air quality as well as near-road air pollution monitoring and characterization.

An WangPhD Candidate

My current research mainly focuses on regional emission inventory estimation and developing modeling chain that bridges traffic assignment, emission calculation, dispersion modeling, exposure and health risk analysis. I am also interested in the energy and environmental impacts of various low-carbon policies and technological trends, especially electrification of transportation system.

Ran Tu, PhD Candidate

Recipient of the 2016-2017: Dr. Mazen Hassounah Graduate Scholarship and the 2017-2018: Dr. M. Hassounah Graduate Scholarship

My PhD research is focused on the improvement of current emission models, and urban traffic policies for emission reduction. I am also interested in air quality related traffic control with emerging technologies, such as autonomous vehicles, and shared mobility.

Laura Minet, PhD Candidate

Recipient of the 2017-2018: Dr. Mazen Hassounah Graduate Scholarship

My research focuses on characterizing ambient air quality to determine population exposure to air pollution. I conduct measurements to understand the relationship between air pollutant levels and the built environment. I also develop dispersion models based on traffic-related air pollutants emissions to develop exposure surfaces and identify hot spots of air pollution.

 

Junshi Xu, PhD Candidate

Recipient of the Mitacs Globalink Graduate Fellowship (2016-2019)

My research mainly focuses on the development of vehicle emission factors through on-board emission measurements and the generation of real-world drive cycles. My research also involves traffic simulation, emission modelling, and air quality modelling. Besides, I have conducted field measurements to investigate the effects of meteorology, built environment, and traffic on near-road air quality.

My current research focuses on modelling the potential impact of environmental policies at the regional level. These policies vary from investigating the traffic emissions of freight demand management strategies; to understanding the potential impact of vehicle autonomy on vehicle ownership and their respective emissions.

Modelling the health benefits of electric cars

Electric vehicles are often touted as a means of mitigating climate change, but a new modelling study suggests that their public health benefits may be just as significant. “Local air pollution within urban environments is highly detrimental to human health,” says Professor Marianne Hatzopoulou (CivMin), who led the research. “When you have an electric vehicle with no tailpipe emissions,… Read more »

CivMin students Alaa Itani and Junshi Xu among DiDi Graduate Awards

  Two CivMin students are among ten University of Toronto graduate students who are receiving DiDi Graduate Awards in recognition of their contributions to the fields of artificial intelligence, vehicle autonomy, transportation analytics, human-machine interfacing and related topics. They are the first U of T students to receive scholarships from Beijing-based Didi Chuxing, the world’s… Read more »

Crunching the numbers on Toronto’s King Street transit pilot

Toronto’s King Street transit pilot project aims to improve transit reliability, speed and capacity, along with a number of other measures included in a comprehensive evaluation and monitoring program. For a team of researchers, it also presents an ideal opportunity to study the effects — both direct and indirect — of traffic changes on air and noise pollution,… Read more »
