LEIDEN – The opening of the Corbulotunnel has led to a significant decrease in car traffic on key access roads in Leiden. This is evident from the mobility monitor presented this week by alderman Ashley North. Traffic volumes on Churchilllaan fell by 47 percent, on Doctor Lelylaan by 32 percent, and on Europaweg by 26 percent. Meanwhile, traffic on Lammenschansweg increased by 15 percent. According to the municipality, the morning rush hour has also been relieved by 20 to 25 percent since the tunnel opened.
In addition to improved traffic flow, bicycle use has also risen. Between 2021 and 2024, the number of recorded bicycle trips at the city’s gateways increased by more than six percent. To accommodate this growth, cycle paths have been widened, new routes have been created, and additional bicycle parking facilities have been installed.
Traffic safety remains a top priority
Although traffic safety remains under pressure, a large majority of residents still feel safe on the roads. In 2021, 87 percent of residents reported feeling mostly or always safe; by 2023, this figure had decreased to 79 percent. The municipality acknowledges this decline in perceived safety but is taking active steps to improve road safety.
Work is currently underway to improve traffic conditions at locations such as Lammenschansweg, the Posthof roundabout, Wassenaarseweg, the bicycle roundabout at Herenstraat, and in the Houtkwartier area.
Increased satisfaction with parking
Another notable development highlighted in the mobility monitor is the growing satisfaction with parking facilities. Satisfaction with residential parking rose from 65 percent in 2021 to 77 percent in 2023. Visitor parking satisfaction also increased, from 58 percent to 63 percent. The municipality attributes this improvement to changes in parking policies and the expansion of parking facilities.
Alderwoman Ashley North emphasizes that while Leiden has made significant progress, continuous efforts are needed to keep the city safe, livable, and accessible.
