Webinar: Integrating explicit and implicit methods in travel behavior research: A study of driver attitudes and bias

Tuesday, February 21, 2017, 10:00am to 11:00am PST

Car crashes are still a leading cause of death in the United States, with vulnerable road users like bicyclists and pedestrians being injured or killed at rates that outpace their mode share.

Planners, engineers, and advocates are increasingly adopting Vision Zero and Tactical Urbanism approaches and trying to better understand the underlying causes of dangerous roadway interactions. However, existing research into crash causation has focused on instrumental factors (e.g. intersection type, vehicle speed) while little research has probed the role of attitudes or socio-cognitive mechanisms in interactions between roadway users.

Social psychology suggests that attitudes and social cognitions can play a role in conflict. Drivers’ attitudes toward bicyclists, and how those attitudes may affect drivers’ behavior, are a largely unexplored area of research, particularly in the United States.

This study is the first use of an implicit method to examine transportation biases between drivers and bicyclists. The research used an Implicit Association Test as well as an attitudinal survey to measure drivers' attitudes toward their own driving behavior, other drivers, and bicyclists.

Exploring the Positive Utility of Travel and Mode Choice

Civil & Environmental Engineering: Patrick Singleton

Why do people travel? We traditionally assume traveling is a means to an end, travel demand is derived (from the demand for activities), and travel time is to be minimized. Recently, scholars have questioned these axioms, noting that some people may like to travel, use travel time productively, enjoy the experience of traveling, or travel for non-utilitarian reasons. The idea that travel can provide benefits and may be motivated by factors beyond reaching activity destinations is known as “the positive utility of travel” or PUT.

This study presents a conceptual and empirical look at the positive utility of travel and its influence on travel behavior. First, PUT is linked to concepts like utility, motivation, and subjective well-being, and categorized into destination activities, travel activities (multitasking), and travel experiences. Then, preliminary results from a 2016 survey of Portland-area commuters are presented. Finally, implications of the PUT concept for transportation...

Big data and the future of travel modeling

Friday, March 3, 2017, 12:00pm to 13:00pm PST

New technologies such as smart phones and web applications constantly collect data on individuals' trip-making and travel patterns. Efforts at using these "Big data" products, to date, have focused on using them to expand or inform traditional travel demand modeling frameworks; however, it is worth considering if a new framework built to maximize the strengths of big data would be more useful to policy makers and planners.

In this presentation Greg Macfarlane will present a discussion on elements of travel models that could quickly benefit from big data and concurrent machine learning techniques, and results from a preliminary application of a prototype framework in Asheville, North Carolina.

Dr. Macfarlane is an analyst in the Systems Analysis Group of WSP | Parsons Brinckerhoff, developing and applying advanced travel demand models. His research and expertise includes trip-based models, activity-based models, integrated land-use/transport...
