To allow hospital staff to get to their workplace without difficulty, Île-de-France Mobilités and public transport operator Régie Autonome des Transports Parisiens (RATP) worked in close collaboration with the university hospital trust operating in Paris and surround region, the Assistance publique - Hôpitaux de Paris (AP-HP), to provide 20 shuttle buses to transporting hospital staff between major transport and hospital hubs. The service is reserved exclusively for hospital staff and operates in addition to the continuity of service on the Ile-de-France network, which has maintained services, albeit reduced, to ensure continuity of other fundamental functions (e.g. police, firefighters, public services, pharmacists, staff working in supermarkets, etc.).
