Note 1: Installation rates are indicative only.
Note 2: Rates vary based on:
- Crossing width
- Traffic volume
- Track condition
- Signal complexity
- Ground conditions
Note 3: Installation calculation formula:
T = (BT × WF × CF × TF) + SC, where:
- BT = Base time
- WF = Width factor (1.0-1.5)
- CF = Complexity factor (1.1-1.4)
- TF = Traffic factor (1.0-1.3)
- SC = Signal constant
