Counting calories on the road. (Technology).People seem innately in·nate adj. 1. Possessed at birth; inborn. 2. Possessed as an essential characteristic; inherent. 3. Of or produced by the mind rather than learned through experience: programmed to devote a fixed amount of metabolic energy--an average of 240 calories, or the energy in a hot dog--to traveling around each day, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. an analysis of the habits of thousands of people in England. That's about a tenth of a person's total daily energy outlay, the analysts say. The finding may give transportation planners a new tool for predicting travel behavior Travel behavior is the study of what people do over space, and how people use transport. The questions studied in travel behavior are broad, and are very much related to activity analysis and time use studies. , such as how much bike riding a person might do after his or her bus commute TO COMMUTE. To substitute one punishment in the place of another. For example, if a man be sentenced to be hung, the executive may, in some states, commute his punishment to that of imprisonment. from work, says civil engineer Robert Kolbl of the University of Technology Vienna in Austria. He and physicist Dirk Helbing of the Dresden University of Technology The Technische Universität Dresden (usually translated from German as Dresden University of Technology and abbreviated TU Dresden or TUD) is the largest institute of higher education in the city of Dresden, the largest university in Saxony and one of the 10 in Germany present their analysis in the on-line New Journal of Physics. In the past, researchers have round that the average time people spend traveling each day remains roughly constant. For example, if their commute time to work decreases, they travel more in their off hours. Based on data on British travelers from 1972 to 1998, Kolbl and Helbing find that average daily travel time actually does vary for users of different transportation modes--say walking versus driving. Even so, the travelers' average daily metabolic expenditures in terms of calories are the same, the researchers say. An important implication, says Kolbl, is that making travel faster and easier--and therefore less calorie-intensive--won't reduce the overall amount of traveling people do.--P.W. |
