SAFE TRAIN SEPARATION IN MODERN RAPID TRANSIT SYSTEMS

Modern rapid transit systems are equipped with automatic train control, slip-spin control, brake assurance system and emergency braking system. Therefore, the reaction times and operating conditions are more predictable and the braking distances can be calculated with a high degree of confidence. This paper describes a computer model for designing speed profiles in a transit system to optimize headway and average speed characteristics without compromising safety margins. The model may also be used to calculate safety margins when the transit system operates under impeded mode conditions.
