The best low-volume street design doesn't need a "No Trucks" sign. It has a curve that trucks can't take.

If you want trucks off a residential street, design a corner radius tight enough that a truck can't navigate it. No sign. No enforcement. The geometry excludes what it's supposed to exclude. Signs ask for behavior. Geometry creates it.

Traffic has been awful today (from the seat of a public bus). Perhaps the sudden heat is a catalyst. Huge delaying events not from big incidents but from something involving ONE vehicle.

As a pedestrian, cyclist, public transport user and a driver, traffic calming is needed but when one small incident grinds to a halt a major thoroughfare, road design needs a rethink.

A diagonal diverter lets bikes through and stops cars. That's not a compromise. That's the goal.

It cuts a four-way intersection diagonally. Cars can't make through movements. Bikes and pedestrians pass through the gap. Cut-through traffic disappears. Cycling gets a direct route. The street gets quieter. Local access remains. This is what residential street prioritization looks like.

The road you designed is the speed your drivers chose. That's on the engineer.

When speeds consistently exceed the posted limit, the default explanation is driver behavior. But if the geometry communicates a higher speed, drivers are responding to the design. That's a design failure. Engineers who design roads that produce speeds above the limit have designed the wrong road.

Five weeks after drivers complained about long waits after a concert in downtown St. Louis, 4 bump-outs, traffic safety features at intersections, were removed. Five weeks. With no public meetings, no engagement. The city repeatedly tells us it takes months, even years to get community feedback on road changes. But this time, it took 5 weeks with no public meetings. It's been made clear that traffic flow for commuters is more important than safety for residents.

If I lived on that street, I would set up a tyre garage, alloy wheel refurb place and bodyshop nearby 😁

Presumably this is deliberate, to discourage SUVs and other larger vehicles from that lane whilst letting through smaller ones - I think it needs more signs on approach (like a similar #TrafficCalming scheme in Britain would use), but surely its obvious to those in larger #cars that their vehicle may not easily fit through that gap, and they should take the lane to the left?
