Abstract:
A study of the allocation of time and trip making across time of day, day of week, and month of year, as well as over the past 40 years, revealed some interesting findings. People are working much more, shopping somewhat more on weekends, and staying at home less today than they did 40 years ago. Time spent in travel on each weekend day (Saturday or Sunday) exceeds that on any weekday, as it did 40 years ago. Time spent shopping on a typical day in the busiest month (December) is more than twice that in the least busy month (September). Monthly variations in daily time in travel exceed 10%. The time-of-day patterns of shopping and other trips for workers and nonworkers are both rational: nonworkers peak in midday away from rush hour, whereas workers peak just after work, indicating trip chaining.
