    Design a function for the fleet management system that standardizes route identifiers by converting snake_case route parameters to camelCase format to maintain consistency across the delivery tracking platform. The function should process any route-related identifier string containing underscores and transform it into the system's standard camelCase notation, ensuring seamless integration with the route optimization engine.
