Abstract

A system and method for performing braking operations on a hyperloop pod are disclosed herein. The hyperloop pod may have a secondary braking system, wherein the secondary braking system may be operable to provide a first braking force. The hyperloop pod may have a transponder communication system and a line-of-sight system, wherein the line-of-sight system may be operable to detect a second hyperloop pod at a line-of-sight distance. The hyperloop pod may have a memory and a processor operable to detect a second hyperloop pod and determine a collision margin between the hyperloop pod and the second hyperloop pod. The hyperloop pod may engage the secondary braking system if a safety margin is equal to or greater than the collision margin.
