An Exploratory Study Using an AIDS Model For Tradeoffs Between Time Allocations to Maintenance Activities/Travel and Discretionary Activities/Travel
The authors of this report propose a linear constraint in time allocation between activities and travel, which indicates a minimum amount of travel one must do in order to allocate one unit of time to the activity. This minimum amount of travel is represented by the travel time price, a ratio obtained by dividing the total amount of time traveling to maintenance or discretionary activities by the total amount of time spent on activities of the same type. This study considers two questions: “If the travel time price of performing maintenance or discretionary activities increases, how will that affect one’s time allocation to those activities? If one had one more unit of available time, how would this affect time allocation to maintenance and discretionary activities?” With respect to the time equivalent of income elasticities of maintenance and discretionary activities, findings show that maintenance activities are a necessity and discretionary activities are a luxury. With respect to travel time price elasticities, if the travel time price of performing a certain type of activity increases (for reasons such as traffic congestion), less time would be allocated to that type of activity. As expected, time spent on maintenance activities is less elastic than the time spent on discretionary activities. As for the cross travel time price elasticities, results suggest a substitution effect between maintenance and discretionary activities.
