For How Long and How Quickly Do Different Groups Chain Their Fixed Activities?

This paper presents the results of the culminating stage of an activity based analysis methodologies framework for integrated fixed activity chaining schedules. What is central to this framework is the extent to which the type, sequence, duration, and timing of fixed activities influence trip chaining. Preceding cluster analysis methods, space-time prism concepts and discrete choice models were applied to locate unique population groups, identify distinct activity travel patterns, and analyze the choice to make a chained link right after the completion of an activity. In this paper, hazard-based duration models are used to analyze the time of chaining events by first studying the duration of a chained journey. Then, with a goal of defining a time threshold to the occurrence of trip chaining, it studies the duration of time elapsed until a chained link is made following a fixed activity. The goal of this paper is to determine scenarios in which chaining events have a higher risk of occurring. Data from the 1998/99 Mobidrive six-week travel diary survey is used in the analyses. This paper focuses on the effects of five types of fixed activities on trip-chaining behavior: work, work-related, school, further education, and club/group meetings. This research helps us understand factors influencing a person’s decision to participate in a trip chain, allowing motivations behind trip-chaining behavior to become more tangible. One of the resulting highlights is the discovery that the chaining behavior of individuals is influenced in different ways among different population subgroups.
