unit: car,
unit of flow: car/minute, could be described as car flow, in terms as light, heavy, modrate, or with numbers.
b. it would describe how crowed the road is, and how likely a crash is coming.
c. move the cars closer, as in a train..hook them together.
for lower current, but hght speed, keep them apart by six or 10 lengths, they can go really fast that way..many freeways are metered on the onramps to do this...makes higher speed, and reduces chance for accidents.
Suppose you were asked to develop a concept of "automobile current" ( a current formed by moving cars) for traffic on an interstate or busy street near you.
a) what would be the units of "automobile current"?
b) what info would be the "automobile current" provide?
c) explain how it would be possible to have a higher current but a lower average speed at one time and a lower current but higher average speed at another time.
Thank you!
