Effects of travel time delay on multi-faceted activity scheduling under space-time constraints: A simulation study

Abstract

This paper presents the results of a study, which simulates the effects of travel time delay on adaptations of planned activity-travel schedules. The activity generation and scheduling engine of the Albatross model system is applied to a fraction of the synthetic population of the Rotterdam region, The Netherlands. Drawing from a truncated normal distribution of speed, the mean of which is equal to average speed, travel time delays for a set of links are simulated. Albatross is run using these travel times delays as input to simulate the effects on activity-travel schedule behavior. The paper reports differences in various aspects of activity-travel schedules. Results indicate that travel time delay affects activity participation the most.
