Theoretical maximum capacity:
The maximum volume that can be possible on the road in the most ideal condition is called theoretical maximum capacity. It occurs with no jam, no congestion, and no delay condition. It can be denoted by C.
Theoretical maximum capacity, \({\bf{C}} = \frac{{1000{\bf\ {v}}}}{{\bf{S}}}\)
Where, v = Traffic flow speed(km/h)
S = Center to center spacing of vehicles(m)
C = Theoretical maximum capacity(vehicle/hour/lane)
Calculation:
Given, v = 40 km/h and S = 12.8 m
Theoretical maximum capacity, \({\bf{C}} = \frac{{1000{\bf\ {v}}}}{{\bf{S}}}\)
\({\bf{C}} = \frac{{1000 \times 40}}{{12.8}}\)
C = 3125 vehicle/hour/lane
