1. A method comprising:
determining, using at least one processor, a stopping distance for a vehicle travelling on a route using at least one of a driving speed of the vehicle, one or more deceleration parameters, one or more timing parameters, or at least one braking mechanism;
identifying, using the at least one processor, one or more sensors of the vehicle that have respective detection ranges less than the stopping distance;
upon identifying the one or more sensors, deactivating, using the at least one processor, at least one operation of at least one sensor of the one or more sensors;
at a time subsequent to deactivating the at least one operation of the at least one sensor, determining a current stopping distance for the vehicle traveling on the route;
determining, using the at least one processor, whether the current stopping distance for the vehicle is less than an activation distance threshold of the at least one sensor, wherein the activation distance threshold is greater than the detection range of the at least one sensor; and
in response to determining that the current stopping distance of the vehicle is less than the activation distance threshold of the at least one sensor, reactivating the at least one sensor for operation.
