About me

I am an assistant professor at the Department of Geography and Planning at the University of Saskatchewan (U of S). Before Joining U of S, I was an NSERC postdoctoral fellow at the University of Toronto Transportation Research Institute (UTTRI), Toronto, Canada. I have obtained my Ph.D. from the School of Urban Planning at McGill University, Montreal, Canada. I have several years of experience in conducting a wide range of transportation projects that adopt evidence-based practical approaches to influence decision-making. These projects were developed for a number of transit agencies and several private and public entities in North America.

I am currently serving on two committees at the Transportation Research Board in the United States, namely on the Standing Committee on Transit Management and Performance (AP010) and Standing Committee on Light Rail Transit (AP075). I am also an associate editor of the Journal of Public Transportation and on the editorial board of the Journal of Canadian Planning and Policy. I have also chaired the public transport track of the 2021 World Symposium on Transport and Land Use Research, which took place in Portland, Oregon, in August 2021.

Teaching & Supervision

GIS application in urban and transport planning Land use and transportation planning Public transit planning and operations

I taught and currently teaching several undergraduate and graduate courses that focus on Planning Field Methods, Equity in Planning, Land Use and Transportation Planning, Public Transit Planning, Quantitative and Qualitative Research Methods, Data Analytics and Visualizations, and Geographic Information Systems (GIS)


Big data Bus Cycling Data analytics GIS Operations Planning Rail Streetcar Transit Transportation Travel behaviour Walking

My research interests include land use and transportation planning, public transport planning and service operations, urban data analytics, and social equity in planning. I work at the intersection of these areas towards the overarching goal of formulating effective policies that enhance the quality of life and well-being of our communities. The topics I am currently focusing on include transit system resilience, passengers’ perception and satisfaction, travel behaviour and transit ridership, and accessibility measures and social equity.

I always welcome new MSc and Ph.D. students to my research group, who are interested in pursuing a degree related to transportation planning at the University of Saskatchewan. I’m particularly interested in students with a background in planning, computer science, geography, or transportation engineering. Students should have official training and experience in spatial analysis using R or ESRI Software (ArcMap or ArcGIS Pro), and in statistical analysis and modelling using SPSS, STATA or R. Knowledge of programming languages, particularly R scripting, is generally desired. If you are interested in joining my research group, send me an email (ehab.diab@usask.ca) that summarizes your skills, previous experience, and research interests.
