30 km zones in Prague are nothing unusual. Yet every time their introduction is discussed, they spark lively debate as if they were something completely new. That’s why Městem na kole has prepared two unique maps showing where you can find 30 km zones across Prague – and where they are missing.
The first major wave of introducing 30 km zones came around 2012–2014. At that time, Prague was expanding paid parking zones, and with them came “area-wide 30 km/h zones.” Paradoxically, it wasn’t mainly about safety — the primary reason was cars.
In a 30 km zone, not every pedestrian crossing needs to be marked, and parking can be placed closer to intersections. This allowed the creation of more parking spaces and simplified traffic signage. As a result, large parts of residential districts, especially in the wider city center, have had 30 km zones for over a decade.
More recent examples, such as in Prague 3, 7, or 8, show a shift. When introducing 30 km zones now, it’s no longer just about parking, but also pedestrian safety, calming traffic, and improving conditions for cycling. Technical standards, for instance, recommend allowing two-way cycling in one-way streets within 30 km/h zones — something that has become increasingly common in recent years.
Still, many older 30 km zones in Prague lack two-way cycling access, and pedestrian crossings are not always designed safely.
Our maps show the whole city at a glance.
The map clearly shows that large parts of Prague already have 30 km zones, especially the wider center with residential blocks and paid parking. In contrast, on the outskirts or in areas dominated by main roads, 30 km zones are more of an exception.
Does your street fall within one of the 30 km zones? Do people keep the speed limit there? Is your neighborhood accessible enough by bike? And where would you welcome more traffic-calmed zones? Do you know of a 30 km zone missing from the map? Let us know.
The maps are based on open OpenStreetMap data, which the Městem na kole editorial team edits and maintains in Prague — both in terms of cycling infrastructure and in terms of traffic-calming measures such as 30 km/h zones.
