When driving in an area without designated lanes for vehicles and pedestrians, where they share the same space, is the driver obliged to yield to pedestrians who are moving around the area?

Why?

The picture shows pedestrians walking on the same parking-area surface used by vehicles. Where there is no separate carriageway and pedestrian route, drivers must travel slowly and give way to pedestrians. This duty applies whether or not a pedestrian crossing is marked.
