    Given a list of traffic density indicators for different route segments in a delivery network, determine the number of route segment pairs that would be compatible for fleet distribution based on their XOR compatibility score (where an even XOR result indicates compatibility). Each indicator is an integer representing the combined traffic status of a route segment, derived from real-time sensor data.
