    Create a function that converts a delivery route's numeric identifier into its binary code format used by the fleet management system's route optimization algorithm, where the output must be a string containing only 1's and 0's without leading zeros. This conversion is essential for the system to efficiently categorize and process parallel delivery paths across the transportation network.
