One-way pavements against virus

One-way pavements and aisles would decrease the frequency of getting too close or bumping into each other, thus the number of people an infected person would meet and infect. Pedestrians on more-or-less populated pavements and aisles should walk in the same direction. Arrows can be painted on the floor. In the street pedestrians can go the same way as cars go (keep left, clockwise in the UK, Japan, etc.; keep right, anticlockwise in Europe, the USA, etc.). While car traffic is reduced it is easier to cross the road.
