Forcing prostitution in public places in Switzerland

I have to say these "sex boxes" hardly see like they provide much privacy.  Is the lack of privacy one way to cut back on prostitution?  From the UK Telegraph:

The drive-in "sex boxes" as they are being called, will be officially opened on August 26, as part of a drive by authorities in Zurich to regulate prostitution, combat pimping and improve security for sex workers.
The nine garage-style structures, located in a former industrial zone in the west of the city, have been organised with typically Swiss precision.
Drivers will have to follow a clearly marked route along which up to 40 prostitutes will be stationed.
Once they have chosen one of the women and negotiated a fee, they will drive into one of the wooden sheds, which are hung with posters advocating the use of condoms and warning of the risk of Aids.
The sex boxes are equipped with alarms which the prostitutes can activate if they feel in danger from a client. . . . Men who solicit street workers outside three new approved zones, including the cluster of sex boxes, will face fines of up to 450 francs (£310). . . .
