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!
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.
a) The units of "automobile current" could be measured in terms of the number of cars per unit of time. For example, it could be expressed as "cars per minute" or "cars per hour."
b) The "automobile current" would provide information about the density of cars on the road during a specific period of time. It would give an idea of how many cars are passing through a particular point in a given time frame.
c) It is possible to have a higher current but a lower average speed at one time due to traffic congestion. When there are many cars on the road, they may be moving slower or even stopped, resulting in a higher current but a lower average speed. This could occur during rush hour or in areas with heavy traffic.
Conversely, it is possible to have a lower current but a higher average speed at another time. This could happen when there are fewer cars on the road, allowing for faster speeds. For example, during non-peak hours or in less congested areas, the number of cars passing through a specific point may be lower, resulting in a lower current but a higher average speed.
In summary, the "automobile current" concept would provide information about the density of cars on a road during a specific time period and can vary depending on the traffic conditions, which may affect the average speed of the cars.
