From the Telegraph:
German nursing homes are using a novel strategy to stop Alzheimer's patients from wandering off: phantom bus stops.
The idea was first tried at Benrath Senior Centre in Düsseldorf, which pitched an exact replica of a standard stop outside, with one small difference: buses do not use it.
The centre had been forced to rely on police to retrieve patients who wanted to return to their often non-existent homes and families. Then Benrath teamed up with a local care association called the "Old Lions". They went to the Rheinbahn transport network which supplied the bus stop.
