Given the signage shown, who has right of way?

The sign in the question, "Play and stay zone", indicates specially adapted circulation zones that are intended primarily for pedestrians and in which the following special traffic rules apply: - The maximum speed of vehicles is set at 10 kilometres per hour; - Drivers must give priority to pedestrians; - Vehicles may only park in places designated by signs or markings; - Cycles and, where applicable, PMVs, may travel in both directions, unless the competent authority establishes otherwise; - Pedestrians may use the entire circulation zone and therefore pedestrian crossings are not marked; - Games and sports are authorised within it. It will always be accompanied by sign R-301 which will limit the speed to 10 km/h.
