Abstract

The present paper attempts to describe the commuter behavior of a sub-urban work trip through a development of a departure time choice model based on disutility minimizing approach. The model assumes that the commuters choose their departure time regarding the time attribute given the minimum value of the sum both disutility types, disutility of earliness departure time from home and disutility of lateness arrival time at the work place. In the model application, we use data from a trip characteristics survey for sub-urban commuters in Makassar, Indonesia. The result shows that the model is applicable significantly regarding the statistical assessments. Further, the commuters have threshold arrival time at work place near to the start work time. We expect that the model provides a basis in continuous further studies, such as the choice model that consider 24 hour life cycle, and a simultaneous choice model incorporating travel mode choice.

Key Words: departure time choice, disutility, sub-urban, work trips.
