Paula Nguyen – Determining the Factors that Influence the Probability and Time to Streetcar Bunching Incidents @ ITS Lab and Testbed, SF3103 , University of Toronto
Sep 22 @ 10:00 am – 11:00 am

Bunching is a common operational problem in surface transit systems with negative impacts on service quality and users’ perception.

While many studies have focused on understanding the causes of bus bunching and developing strategies to mitigate its negative effects, there has been little research on streetcar bunching. This research aims at understanding the factors that impact the likelihood of streetcar bunching and to investigate the factors that impact the time to the initial bunching incident from terminal.

Focusing on Toronto’s streetcar lines, this study developed a binary logistic regression model and an accelerated failure time (AFT) model to address the first and second goals, respectively.  Data from multiple sources, including the automatic vehicle location (AVL) system, were used to estimate the models.

Headway deviations at terminal and the usage of different vehicles types were two interesting factors found to increase the odds of bunching and accelerate the time to bunching.

Dr. Kelly Clifton – A Framework for Integrating Pedestrians in Travel Demand Models @ Sidney Smith Hall, Room SS 1071
Sep 22 @ 11:00 am – 12:30 pm

This presentation will introduce a framework and proof of concept application from Portland, Oregon that facilitates the integration of walking activity into four-step travel demand models, allowing cities and regions to implement these advances with minimal changes to existing modelling systems. Specifically, the framework first changes the spatial unit from Transportation Analysis Zones (TAZs) to Pedestrian Analysis Zones (PAZs), a finer-grained geography better suited to modelling pedestrian trips. Then, pedestrian trip origins and destinations are identified using trip generation and destination choice models. The opportunities and challenges for advancing and implementing this framework are discussed.

Kelly J. Clifton is a Professor of Civil and Environmental Engineering at Portland State University. Dr. Clifton conducts research and teaches courses in various aspects of transportation planning and policy, including: travel behaviour, land use and transportation, physical activity and health, and travel survey methods. She is an affiliate of the National Institute for Transportation and Communities and a fellow in the Institute for Sustainable Solutions, both housed at Portland State University. She was the inaugural chair of the World Society for Transport and Land Use Research. Her latest research develops methods to evaluate the transport impacts of new development, quantifying equity issues in transport, anticipating impacts and applications of “smart” cities’ technologies, and modeling demand for non-motorized modes.

A Geography and Planning Intersections Seminar co-sponsored by the University of Toronto Institute of Transportation Engineers Student Chapter (UT-ITE) and the University of Toronto Transportation Research Institute (UTTRI).

Jason Hawkins – An Atypical RTM – Development of the RM of Wood Buffalo Regional Travel Model @ ITS Lab and Testbed, SF3103 , University of Toronto
Sep 29 @ 11:00 am – 12:00 pm

Regional transportation models (RTMs) are a common planning tool in most major North American cities.

This presentation outlines the development of such a model for an atypical region – the Rural Municipality (RM) of Wood Buffalo in Alberta. This is a dynamic region characterized by heavy oil extraction and transient populations residing in work camps. It presented unique design challenges in terms of accurately representing travel patterns for large populations of shift workers, with travel mode choice being largely determined by private firms rather than individual preference and government policy.

The challenges in applying tour-based models developed for urban contexts to such a region are reviewed.
