The ADAC attributes the increase in traffic jams to a 4% rise in traffic volume and a high number of construction sites, calling for modernization and expansion of traffic infrastructure.

The introduction of the Germany Ticket, which has gained 13 million users, primarily among commuters, has helped alleviate road traffic during peak times.

Traffic jam measurements are derived from data collected via truck fleets and smartphone apps, defining a traffic jam as a situation where speed drops below 20 kilometers per hour for a sustained period.

Peak traffic congestion typically occurs around holidays and vacation months, particularly in May, June, August, September, and October.

In 2024, traffic jams in Germany totaled 448,000 hours, an increase of 21,000 hours compared to the previous year.

Despite this rise in traffic jam duration, the overall length of traffic congestion slightly decreased to 859,000 kilometers.

Unplanned road closures have been found to significantly disrupt traffic flow, while planned maintenance allows for continued movement.

Fridays see a peak in traffic jams around midday, while weekends experience the most congestion late morning to noon.
