Breakfast, two refreshment breaks and lunch are provided daily.


A travel demand analysis consists of assessing four components of the travel pattern for a study area: i) trip generation (TG) or where trips are coming from; ii) trip distribution (TD) or where trips are going to; iii) modal split (MS) or the shares among available modes for the flow between origin-destination (O-D) pairs; and, iv) network assignment (NA) or the route choice within each mode. The standard "state-of-the-practice" in travel demand modeling is the sequential or four-step approach.

This modeling strategy estimates the four travel demand components sequentially and feeds the results from one component to the next component in the sequence. Assessing these components provides insight into the effectiveness of transportation policy and the performance of transportation infrastructure. The demand for transportation forms the primary input to any decision related to construction and management of transportation and traffic facilities such as roads, intersection, parking lots, transit system, etc.

The main objective of this two-day workshop is to provide participants with a fundamental understanding of the nature of transportation demand and how it can be analyzed. This workshop will cover the sequential demand analysis technique, the most frequently used method of determining the transportation demand.  Finally, it will cover some of the data collection methods used in travel demand analysis.
Target Audience

This course will be of interest to transportation planning practitioners who work for municipal, provincial, and federal government transportation planning agencies, traffic/transportation Engineers, professionals new to the field or professionals looking for a refresher course, and students in transportation analysis, modeling and planning.

Learning Outcomes

At the conclusion of the course, participants should be able to:

  • Identify land use and transportation variables that influence vehicle trip generation rates.
  • Estimate the total number of trips generated in the study area using the trip generation models.
  • Use the outputs of the trip generation models to determine the number fo trips between all zone pairs using the trip distribution models.
  • Estimate the shares of these trips for different modes using mode choice models.
  • Finally, use the traffic assignment models to estimate the traffic volume on each link of the network.
