A study by the website korkowo.pl has found that Wroclaw's rush hour traffic is moving at least 2km/h slower than every other major Polish city.
The research involved monitoring the average speed of traffic in Poland's major cities both before and after the holidays.
In most of the cities the average speed was found to be much less during the morning rush hour as opposed to the evening one.
In terms of the difference in average speed between the holiday period and September/October, it was the capital Warsaw where the biggest drop (4km/h) was recorded. Cars stuck in Wroclaw's morning rush hour traffic moved just 2km/h slower after the end of the holiday period.

However, the figures did find that in September and October, the slowest city in the morning rush hour was Wroclaw, where the average speed was 36 km/h, 2 km/h less than Warsaw. In the evening the gap between the cities grew slightly further to 33 and 36km/h respectively.
The only city that seems to be unaffected by the seasonal traffic is Szczecin, where drivers cruised around at peak times at an average spped of 39 km/h.
The stats will push further pressure on the local authorities to take action to reduce traffic in Wroclaw. The news also comes in the midst of a series of articles titled "Wroclaw road absurdities", published by local newspaper Gazeta Wroclawska, where readers have been chipping in with their complaints about the city's road layouts.
