Identifying Market Segments based on Observed Travel and Activity Patterns

The video begins at 1:47.

Abstract: In transportation planning and engineering, market segments or groups of individuals with varying attitudes and travel behavior are often identified in order to define a set of policies and strategies targeted at each segment. Examples include residential location choice studies, electric vehicle adoption and the marketing of public transit options. Defining market segments is common in the marketing literature, typically based on observed socioeconomic characteristics, such as gender and income. However, in addition to these characteristics, travelers may also be segmented based on variations in their observed travel and activity patterns. The activity-based approach to travel demand analysis acknowledges the need to analyze the travel patterns of individuals, conceptualized as a trip chain or tour, as opposed to individual trip segments. This has implications for identifying markets segments based on travel patterns which needs to distinguish between the sequencing and timing of travel choices and activities, in addition to the actual travel choices and activities. One approach that holds promise is pattern recognition theory which has wide applications in image analysis, speech recognition and physiological signal processing. In this study, pattern recognition methods are applied to observed daily travel and activity patterns from Oregon to identify travel market...

Electric Vehicles: Are We in The Driver's Seat?

The video begins at 9:18.

Abstract: When it comes to electric vehicles (EVs), Oregon has all the right ingredients: the Governor's support, the necessary infrastructure and investment by major manufacturers; but is that enough to ensure success? George Beard, Portland State University's conduit to Portland General Electric (PGE) and other EV partners, will provide a briefing on the status of EV deployment and adoption in Oregon. His talk will examine remaining barriers to EV adoption and the conditions in which key parties can overcome them. Can the professionals who are working on EVs, including planners and engineers, have any impact on the most important measure of success: consumer acceptance? Sit down, plug in, and find out!

Emerging Implications of Electric Bicycles

Room 204 of the Distance Learning Center Wing of the Urban Center on the Portland State University campus

Abstract: A variety of types of electric bicycles are now available to consumers in America and around the world. While there has been strong uptake of these vehicles in China, there remains uncertainty in other markets about their ultimate potential as a transportation mode. The technology is evolving in ways that are likely to better meet traveller's needs and the growth of this mode presents both opportunities and challenges. Since they have implications for transportation policy, planning and operations it is appropriate for the transportation profession to consider these vehicles carefully. This seminar will review developments and emerging issues with this form of transportation technology.
