    Given a route identifier string containing traffic density codes, priority levels, and zone markers for a delivery route, create a function that converts this string into a single character route classification (A-Z) by summing the ASCII values of all characters in the identifier and taking modulo 26 of the result. The resulting character will be used to quickly categorize and prioritize delivery routes in the fleet management system.
