WARSAW, Jan. 22 (Xinhua) -- Two Polish cities, Lodz and Lublin, were ranked among the world's most congested cities in 2025, according to the annual Traffic Index released by navigation-device maker TomTom.
Lodz, Poland's fourth-largest city with around 650,000 residents, placed fourth globally with a congestion level of 72.8 percent, meaning travel times were that much slower than under free-flowing traffic conditions. Lublin, a city of about 330,000 in eastern Poland, ranked sixth with a congestion level of 70.4 percent.
Mexico City topped the ranking with 75.9 percent, followed by Bengaluru in India at 74.4 percent and Dublin in Ireland at 72.9 percent.
TomTom said the index is based on anonymous GPS data collected from cities worldwide and measures how much traffic slows compared with uncongested conditions.
The company's data also showed that congestion worsened in all listed Polish cities in 2025 compared with 2024.
In Lodz, commuters lost an average of 135 hours a year to rush-hour traffic, while the figure in Lublin was 117 hours, according to the report.
Last year, another global traffic ranking by transport analytics firm Inrix, which uses a different methodology, found that Warsaw had Europe's sixth-highest number of hours lost to traffic jams. ■
