According to a senior Delhi Transport Corporation official, the corporation took the decision after a detailed study of the roads, routes, locations of bus stands and behaviour of drivers.
The ticketing app's trial will be conducted till September 21 in 29 buses on route number 534, connection Anand Vihar Terminal and Mehrauli.
This facility will also be extended to 29 Delhi Transport Corporation (DTC) buses after the trial period completes.
The objective of the project is to ensure the safety and security of the passengers, particularly women passengers.
Under the project, there is a provision for a centralised command room to control and monitor the entire system through GPS locations of the buses and footage from CCTV cameras inside them.
As soon a passenger will scan the QR code and pay the fair online, the bus conductor will receive a notification of payment and the ticket will be sold, said the officials.
The city has around 6,500 public transport buses, including 3,900 run by the DTC and over 2,500 cluster buses operated by the Delhi Integrated Multimodal Transit System.
Social distancing: Drivers of DTC, cluster buses instructed not to drive with over 20 passengers onboard
Delhi Transport minister Kailash Gahlot said if the extra passengers do not deboard after a request from the conductor, driver or marshal, then they will dial 100 to call the police.
The transport department will make sure social distancing norms are enforced at the bus stops and inside the buses.
People using private conveyance can either take Bhavbhuti Marg or Minto Road while those taking DTC buses will have to board from the parking area in front of Ajmeri Gate.
Sisodia, who also holds the finance portfolio, said his government has also planned to build multi-level bus depots, which would be the first of its kind in the country.
The cleaning drive was started after a state-level task force meeting on measures to guard against Corona infection on Monday.
