The good news is that the 2014 result doesn't take into account the fact that Warsaw is now missing one bridge after Lazienkowski bridge caught fire and is now closed indefinitely. I reckon that closure should give Warsaw the push it needs to get back up there as Europe's most congested city!
It's got a lot worse since the bridge stopped. Plus, while they were doing all the road works to connect up the bypass there were horrific jams in the North east of the city.
One exacerbating factor sometimes is when they stop traffic for some dignitary. When Angela Merkel visited, the whole of Trasa £azienkowska was sealed off for 45 minutes (during the rush hour!) before her journey - couldn't they have popped her in a helicopter? They even still stop the traffic for the Premier etc, Soviet-style.
Another problem is poor traffic management sometimes with unphased traffic lights causing gridlock at junctions. That and the very low standards of driving.
Down by the office parks by Galeria Mokotow was always the worst - partly due to a lack of joined up thinking when planning permission was granted to build them without reference to future traffic issues. Under the economic circumstances, that was excusable - the priority was jobs and the economy, but this was very little consolation for people stuck on the bus for an hour.
It is really something praisable the quality of the public transport in most polish cities
They actually do very well, however there is still some room for improvement, especially on commuter routes.
Restricting pensioners' discounts to after 9.30 in the morning and not between 15.30 and 17.30 would be a great help in Warsaw. It's a problem when people doing a full day's work are jammed on buses that stop for longer than they might and others having priority for the seats because of 85 year olds who must, simply must do their shopping every day during the 8am rush hour.
