    Given the total number of alternative delivery routes available, determine the largest number of routes that can be simultaneously analyzed by the binary route distribution system, where this number must be a power of 2. This optimization will ensure the most efficient real-time rerouting of delivery trucks while maintaining system processing capabilities.
