In addition to pedestrians crossing against a red light or in the middle of the street, vehicles that do not stop at the zebra crossings will face fines of up to 500 baht.
Pol Maj Gen Niphon Charoenphol, deputy chief of Metropolitan Police Bureau), said traffic police selected six points where pedestrians had to use crossings. Vehicles will not be allowed to make a right turn at 13 spots to improve traffic flow on this 1.3-kilometre road.
About 30 police officers will be employed to help direct the traffic on the road every workdays between 6am and 8pm. The same measures are likely to be extended to Sukhumvit and Rama 4 roads.
He said the first day of crackdown proved vehicle backups could be cut by about one kilometre.
