Answer:
The sum of all currents entering a junction is 0
Explanation:
Current cannot disappear, so the currents leaving a junction have to equal the currents entering a junction. If you would give the currents leaving the junction an opposite sign (e.g., negative) it implies that the sum of all these currents is exactly 0.
Solution :
Given
Now,
Therefore,
Given,
= 2 + 0.368
= 2.368 min
At user equilibrium,
∴ = 2.368 min
= 1368 veh/h
