Zachary Patterson, PhD

Associate Professor and Graduate Program Director (MASc. and PhD.), Concordia Institute for Information Systems Engineering



Zachary received his PhD from McGill University and was a postdoctoral researcher at the Ecole polytechnique federale de Lausanne in Switzerland in the Transport and Mobility Laboratory (TRANSP-OR). He was Assistant and Associate Professor starting in 2010 in the Concordia University department of Geography, Planning & Environment. In 2021 he joined the Concordia Institute for Information Systems Engineering (CIISE). Professionally he worked as transportation modeler at the Montreal regional public transportation planner, l'Agence metropolitaine de transport. Zachary's research focuses on: the use of emerging technologies in transport-related data collection, computational geospatial data processing, data analysis and inference with statistical and artificial intelligence techniques, and discrete choice experiments.


Teaching activities

Advanced Quantitative Methods

Over the course of the semester, students will become familiar with the R programming environment at least for the conducting of statistical analysis, and hopefully also for data manipulation and preparation. They will become familiar with the kinds of statistical analysis that is typically used in the fields of geography, planning and environmental studies. They will also work towards understanding the type of statistical analysis that is likely to be done as part of their master’s thesis. Ideally, as part of the term project, the student will be able to work with the same data set they expect to use in the analysis for their thesis. Alternatively, another data set that resembles the data they expect to use for their thesis will be used.

It is open to graduate students. Download most recent course outline  here.

Analyzing Choice

Over the course of this class, students learn to design, implement and analyse the data, from a stated choice survey. The topic of the survey will have to do with an important environmental question. It is open to undergraduate and undergraduate students. Download the most recent undergraduate course outline here.


Transportation GIS

Download the latest course outline. This course introduces students to the transportation planning and modeling process aided by the use of a GIS-based transportation decision aid tool. A real-world case-study region and transportation system is used to illustrate the different elements of the planning and modeling process. The course aims to highlight both the strengths and weaknesses (particularly with regards to how it treats the interaction between the transportation system and land-use) of the traditional transportation planning approach.

TRIP Lab

TRIP Lab Smartphone Travel Survey Platform Workshop
May 25 and 26, Concordia University

Download the Workshop Agenda

The TRIP Lab is holding a 2-day workshop on Smartphone Travel Surveys and how to use its new Smartphone Travel Survey Platform at Concordia University.

The TRIP Lab platform enables researchers to create their own free smartphone travel survey application.

The Platform is useful for anyone who wants to collect and analyze data on commuting and urban travel behaviour, including:

  • transportation planning authorities: transit operators, ministries of transportation, etc.
  • academic researchers: faculty and students from civil engineering, urban planning, geography, health, etc.
  • not-for-profits and community groups with a transportation focus
Registration is free, but spaces are limited.

Required: Smartphone [Android 4.1 (Jellybean, API 16) or Apple (iOS8.0 and above,  iPhone4S or newer)]

To register, please write to triplab.workshop@gmail.com


Welcome to the lab

The Transportation Research for Integrated Planning (TRIP) Lab was founded in October 2011 as part of a Canadian Foundation for Innovation (CFI) grant associated with a Tier-II Canada Research Chair in Transportation and Land-use Linkages for Regional Sustainability. The TRIP lab is equipped with high-powered computers and servers for geographical and statistical analysis and is able to house up to 10 student researchers. It is also home to unique and expansive transportation and land-use data for Montreal as well as other major urban regions across the country. Analysis of this data is made possible by cutting-edge and sophisticated software for geographical analysis, transportation modeling and statistical analysis.

Research in the TRIP lab focuses on the modeling of transportation, the environment, land-use and their linkages. It also involves using new technologies to collect data on where people decide to live and how they move around the city. Recently, a smartphone  travel survey application and platform (Itinerum™) has been developed to conduct origin-destination of members of the Concordia community.
