Little work has accounted for congestion, using data that reflects driving patterns, traffic volume, and speed, to examine the association between traffic emissions and human health. In this study, we performed a health risk assessment of PM2.5 emissions during congestion periods in the Greater Toronto and Hamilton Area (GTHA), Canada. Specifically, we used a micro-level approach that combines the Stochastic User Equilibrium Traffic Assignment Algorithm with a MOVES emission model to estimate emissions considering congestion conditions. Subsequently, we applied a concentration-response function to estimate PM2.5-related mortality, and the associated health costs. Our results suggest that traffic congestion has a substantial impact on human health and the economy in the GTHA, especially at the most congested period (7:00am). Considering daily mortality, our results showed an impact of 206 (boundary test 95%: 116; 297) and 119 (boundary test 95%: 67; 171) deaths per year (all-cause and cardiovascular mortality, respectively). The economic impact from daily mortality is approximately

At an age when others might have considered slowing down, Pavlos Kanaroglou was just getting started. Neither his age nor the knowledge that he had chronic leukemia were going to stand in his way. Pavlos had accomplished a lot in his years as an academic (he held, for example, a prestigious Tier 1 Canada Research Chair for two consecutive 7 year terms up to 2015) but he felt the need to do something new and ambitious that would be of additional service to society. Pavlos was integral to the process that led to the formation, in October 2007, of the McMaster Institute for Transportation and Logistics (MITL) and he was the natural choice to take on the role of the Institute’s founding director. MITL was launched in Hamilton, Ontario, Canada which had been Pavlos’ home from the mid-1970s. During Pavlos’ tenure, the Institute completed a substantial body of work, associated with approximately

3.5M in funding. Much of the research that was undertaken intertwined with aspects of Pavlos’ expertise and was quite applicable for his adopted hometown. The purpose of this chapter is to provide a retrospective look at the insights that emerged for Hamilton as MITL grew and as Pavlos did all he could for the benefit of both, and for the development of his students and team members.
