    Design a function that determines the total number of occupied parking spaces in a zone by analyzing its binary occupancy status, where each bit position represents a single parking spot with 1 indicating occupied and 0 indicating vacant. The function should efficiently process the binary occupancy data to provide an accurate count of currently filled spaces, enabling real-time parking availability monitoring in urban areas.
