The space headway between the vehicles moving on urban roads is 2 m. Estimate the maximum traffic density that a road can have under jam condition.
- A400 veh/km
- B450 veh/km
- C500 veh/kmCorrect
- D550 veh/km
Solution
Concept
Jam density
Formula
kj = 1000/s
Step-by-step solution
1. 1000/2 = 500 veh/km.
Explanation
Density equals the inverse of spacing.
Why the other options are wrong
Others do not follow.
Shortcut
1000/spacing.
Correct answer: C) 500 veh/km
