Using the notion of commuting flexibility, this paper investigates the intra-personal day-to-day variability and flexibility of commuting behavior using a 7-day GPS dataset collected in Beijing, China. Four dimensions of commuting variability are evaluated: space, time, travel mode, and travel route. The results indicate that the commute trip is flexible and complex in a variety of ways. Through 3D geovisualizations we were able to identify seven distinctive commuting patterns based on different combinations of the four dimensions of commuting flexibility. The results call into question the common presupposition that the commute trip is stable and fixed in many respects. Among the four dimensions of commuting flexibility, we found that variation or flexibility in time is more common than variation in the other three dimensions of commuting flexibility. This means that temporal adjustment for coping with commute problems is likely to be the most feasible option for suburban residents in Beijing.
