Buses, at seven in the morning of the working day under the rope of people, who in principle have nowhere to rush - a well-known picture.
The Germans solved this problem elegantly (the city of Nuremberg):
Unique travel tickets are sold with discount, costing approximately half the cost of ordinary tickets.
They can be paid to unemployed, pensioners, etc.
Nothing unusual.
The only feature - they do not work on weekdays from six to eight in the morning.
