Auf Dutzenden Berliner Hauptstraßen wurde wegen schlechter Luftqualität Tempo 30 eingeführt. CDU-Verkehrssenatorin Bonde will dies zurückdrehen. Die SPD befürchtet negative Auswirkungen für Schüler und fordert erst eine ausführliche Prüfung.

    There’s a reason it is like that in most of the world, and it is rather stupid. Speed limits are calculated, not mandated.

    Transit authorities record the average speed of drivers in an unmarked stretch of road. Then the speed limit is that average plus some number chosen by local authorities, rounded up. Then the government go ahead and say, “if it is not measured, it is 50”. And you end up with ridiculous numbers all over the place.

    That’s why people say that to limit speed you have to build for the speed desired. Ordering a speed limits lower than the one people do spontaneously, without changing road geometry, doesn’t reduce the overall speed of traffic. It just increases the number of infractions, a common police funding strategy.

    The most successful speed limit projects include infrastructure budgets to change the roads.
