Number of traffic jams in Flanders nears all-time high

Traffic jams on Flanders' main roads continue to grow. In May, the annual average traffic jam amounted to 795 km of traffic jams per working day, according to Statistics Flanders. Only in 2018 has a higher number been recorded.

"The traffic jam severity in May 2023 reached the second highest value since measurements began," reports Statistic Flanders.

Traffic jam severity rose to a peak in May 2018. From March 2020, there was a sharp decline due to the Covid-19 pandemic, but from April 2021 it rose again.

Statistics Flanders' traffic jam severity indicator combines file length with congestion duration and is expressed in km-hours. 100 km-hours is the equivalent of 100 km of traffic jams for one hour or 200 km of traffic jams for half an hour.

The regions of Antwerp and Brussels see the most and longest traffic jams. The Antwerp region accounted for 416 km-hours of traffic jams per working day in May, while Brussels saw 293 km-hours of congestion.
