Those signs are from our largest cities (500k-800k inhabitants). We just don't have such complicated restrictions, probably because we have a stronger separation between through roads and parking space. We just don't have any parking space that is used as a traffic lane during rush hours; if you can park at all in a multiple-lane street, the space tends to be clearly separated. Street cleaning happens during the day; cleaners just have to deal with traffic and parked cars.
