    Create a function that generates a single-character checkpoint code from a route's status string by summing the ASCII values of all characters in the input string (containing traffic, weather, and road conditions) and applying modulo 26 to the result. The resulting character serves as a quick validation code for real-time fleet tracking and route optimization systems.
