Would you agree that a bad signal system can reduce capacity?No. A bad signal system can reduce maximum service levels, not the inherent capacity in the line. So if a bad signal system can reduce capacity, why can't a better one increase capacity? How does one apply metrics to a "bad" or "good" signal system? There's are two metrics: capacity and maximum service levels. Maximum service levels are less than or equal to capacity. One measures the ratio of maximum service level to capacity. |
