These buses travel 21 of 107 subsidized routes in the city, some of which have previously been known for recurrent pickpocketing and sexual harassment on passengers.
According to statistics provided by the public transport authority, the first half of 2016 saw only six reports of rude bus drivers or attendants by passengers, a significant drop from 82 cases against the same period of 2015, before cameras were installed.
The installation of cameras has also helped redirect buses to avoid heavy traffic, the authority said.
According to a senior official at the management authority, surveillance cameras will be installed in all 2,400 subsidized buses in Ho Chi Minh City by the end of 2016.
