Yes, developing public transport can help solve traffic jams. When more people use buses and subways, there are fewer cars on the road, which helps reduce congestion. Public transport can move a lot of people quickly and is often more environmentally friendly, cutting down on pollution. Plus, when public transport is reliable, it makes commuting easier and less stressful for everyone.

I don't think public transport alone can solve traffic jams. Even with good public transport, some areas might not be well-served, so people will still use cars. Also, many people prefer driving their own cars. Traffic jams can also be caused by things like roadworks or accidents, which public transport can't fix. So, we need other solutions too, like better roads and traffic management.

It depends on the city and its infrastructure. In big cities with lots of people, public transport can be very effective. But it needs government support and people willing to use it. It should be part of a bigger plan that includes bike lanes and walking paths. Public transport must be reliable, affordable, and convenient to really help with traffic jams.
