COVID-19 has definitely put the brakes on public transport. With physical distancing being the norm, many people who can afford to, are likely to avoid it, at least for a few more months.
But public means of transport such as the bus and metro will continue to be an efficient and affordable mode of transport for most commuters. Therefore, there is an urgent need to revamp and restructure the services with safety and sanity checks.
Alongside technology, and rules and regulations (distancing, sanitisation, etc.), one critical aspect in the post-COVID world would be behavioural change. Each person, including commuters and operators, has a singular role to play in ensuring social safety.
