While calculating the headway for a particular layout, we need the following inputs such as Line Speed, Dwell time (However N/A for Non-stopping trains), Platform Length, Train Length, Overlap distance for calculating CP, Acceleration, Service Brake, Emergency Brake, Drivers reaction time for placing the Sighting Points and with some assumptions. From this we can calculate the Headway in seconds.
Also if we know the Headway timing we can achieve by adjusting the signal positioning or introducing intermediate signals we can meet.
