Emissions Reduction Potential of Electric Vehicle Deployment in the GTHA: Operationalizing the Concept of Marginal Emission Factors and Uncertainty @ Sandford Fleming Building, ITS Lab and Testbed, Room SF3103
Jan 18 @ 12:00 pm – 1:00 pm

To reduce emissions from the transportation sector, electric vehicles (EVs) are promoted in many regions. However, to estimate the true emission reduction potential of introducing EVs, it is important to conduct the analysis from a life cycle perspective and consider the upstream emissions from electricity generation and gasoline production.

Introducing EVs will increase electricity demand, and only certain types of power generators respond to such marginal increases. To capture such marginal effect of electricity generation and the temporal variation of EV charging, this study:

  1. operationalizes the concept of marginal emissions factors,
  2. utilizes person-level travel activity data, and
  3. simulates five charging scenarios (including an optimal low emission charging strategy) to estimate emissions reduction capacity of introducing EVs in the GTHA.

Many sources of uncertainty and variability exist in current traffic emission modelling tools, which trickle into regional emission inventory.

This study presents a GHG emission modelling tool for transportation, which considers various sources of uncertainty in this process. Both conventional vehicle and EV emissions are considered on a regional level. Fuel-cycle emissions are calculated based on literature-based Well-to-Pump (WTP) emissions and MOVES-based Pump-to-Wheel (PTW) emission. Several EV penetration case studies are developed to investigate the mixed effects of vehicle electrification and WTP emission uncertainty.

Both approaches found that vehicle electrification could deliver substantial GHG savings in the GTHA.

Yijun (Jessie) Gai

Yijun (Jessie) Gai is a MASc candidate in environmental and transportation engineering at the University of Toronto. Under the supervision of Prof. Marianne Hatzopoulou and Prof. I. Daniel Posen, her research focuses on quantifying the reduction in greenhouse gas and criteria air pollutants due to electric vehicles deployment, as well as assessing the associated health and social impacts. Meanwhile, she is interested in policy or program design or implementation strategies that can enhance EV adoption. With her previous research and internship experience, she is also interested in renewable energy.

An Wang

An Wang is a PhD candidate in transportation engineering at University of Toronto. He finished his Masters in the same field at McGill University with Prof. Marianne Hatzopoulou. He has a wide research interest regarding energy consumption and emissions from on-road vehicles. Focusing on the regional level, he is currently working on quantifying and refining the energy consumption and emission estimation process in the GTHA from a life-cycle assessment perspective. His work involves both conventional vehicle and EV and studies them in a comparative way.

All are welcome to attend.

This seminar is presented by the University of Toronto Institute of Transportation Engineers (ITE) Student Chapter.

Ontario Road Safety Forum – 5th Meeting @ Galbraith Building, Room 202
Mar 27 @ 8:30 am – 4:30 pm

Dear Colleagues:

Four Ontario Road Safety Forums were held in the past 2 years and were attended by over 50 people, each representing a broad range of road safety interests (e.g., MTO, Transport Canada, City of Toronto, Region of Waterloo, Peel Region, Hospital for Sick Children, public health, Traffic Injury Research Foundation, MADD, CAA, Parachute, graduate students and professors from Ryerson, Toronto, Waterloo, Lakehead, Western, York, consultants).

The Forum’s objective is to create a networking event with an emphasis on evidence-based road safety. The feedback has been very positive and now we are organizing another forum to take place on March 27, 2019, with registration from 8:30-9:00 a.m. This 5th Forum will once again take place in the Galbraith Building at the University of Toronto, Room GB202.

We are in the process of preparing the agenda, and your participation is most welcome.

Presentations and Speakers

We plan on having ten 5-minute presentations, each followed by a 5-minute discussion period, on a subject of the presenter’s choice. Please send me (asmiley@hfn.ca) an email if you would like to deliver a short presentation with the topic name and a short description by January 18th. Following each presentation, a short time for discussion will be allowed in the agenda. The first ten proposed/appropriate presentations will be added to the agenda.

If you are interested in delivering a longer 15 – 20 minute presentation on an evidence-based road safety study or project, please provide me with a description prior to January 18th so that we can consider it during the planning of the other meeting sessions.

Enrollment

There will be a $35.00 registration fee to cover morning coffee and pastries, mid-morning coffee, lunch, and afternoon juice and pop (whether you consume them or not). Please pay by Interac E-transfer (see your on-line banking) to Human Factors North Inc. at hfn@hfn.ca. Enter “Fee from your name for Ontario Road Safety Forum” in the Message box (so we can record receipt of your fee) and then click on “print” when you complete your E-transfer to produce a receipt. If you need to create a security question, it can be “name of city forum held” with answer “Toronto”.

Please enroll as soon as possible; enrollment will close on March 6th, 2019. Please note that if room capacity is reached, enrollment may need to be closed earlier.

We look forward to hearing from you and seeing you on March 27th, 2019.

Two Short Courses on Public Transit 2019 @ University of Toronto, Galbraith Building, Room GB202
Aug 21 @ 8:00 am – Aug 23 @ 5:00 pm

The University of Toronto Transportation Research Institute offers two back-to-back courses designed to provide participants with knowledge of key concepts and best practices related to public transit service planning and technology.

The first course, Public Transit Planning & ITS (August 21-22), provides an overview of key concepts and best practices related to transit planning, network and service design, service standards, transit and land use, and the application of ITS technologies.

The second course, Public Transit Modelling  (August 23), provides a complementary but more focused and advanced exploration of tools that can be used for forecasting demand at both the system and route levels, transit assignment, and microsimulation-based analysis. The courses will be taught by leading transit planning researchers and practitioners and will provide a balanced perspective on transit systems planning and ITS, including both state-of-the-art techniques and practical perspectives.

More details to come.

Email for more information or telephone (416) 978-4175.
