Effects of Grade
The greater a grade, the more power an animal or a machine requires to climb it at a given speed; therefore routes with lower grades are preferred, so long as they do not have other disadvantages, such as causing the overall travel distance to increase significantly.
Vehicles proceeding up a steep grade demand more fuel consumption with typically increased air pollution generation. Sound level increases are also produced by motor vehicles travelling up a grade.

Famous quotes containing the words effects of, effects and/or grade:
“The ultimate result of shielding men from the effects of folly, is to fill the world with fools.”
—Herbert Spencer (1820–1903)
“Virtues are not emotions. Emotions are movements of appetite, virtues dispositions of appetite towards movement. Moreover emotions can be good or bad, reasonable or unreasonable; whereas virtues dispose us only to good. Emotions arise in the appetite and are brought into conformity with reason; virtues are effects of reason achieving themselves in reasonable movements of the appetites. Balanced emotions are virtue’s effect, not its substance.”
—Thomas Aquinas (c. 1225–1274)
“Life begins at six—at least in the minds of six-year-olds. . . . In kindergarten you are the baby. In first grade you put down the baby. . . . Every first grader knows in some osmotic way that this is real life. . . . First grade is the first step on the way to a place in the grown-up world.”
—Stella Chess (20th century)
