Dimensions of Speed Humps

Of course there are several different types of vertical deflection, with variable effectiveness. The most effective are taller and steeper. The least effective types are most in vogue for reasons you can probably guess. Sorry I don’t have the source for this in front of me.

P.S. One speed hump costs about 2K$, roughly 1/8 the cost of a mini roundabout. By all indications they are far more effective traffic calmers than are mini roundabouts.

The crowd cheered. Bugles rang out. Within a year, Dobbins promised, something similar to Columbus’s short route to the Orient would rise above the hills of the Los Angeles basin. His “Cycleway” was designed to swiftly and conveniently transport people between a pair of key urban centers: the old colonial plaza in Downtown Los Angeles, and Pasadena, the burgeoning, modern suburb to the north that then rivaled the older city in size and ambition. The Dobbins route—which neatly anticipated and presaged the automotive freeways that now stretch across the region—would be a modern marvel. It would boast a state-of-the-art toll-collecting system. It would be elevated fifteen feet above the ground; the limited access would ensure that traffic flowed smoothly. “It can be said,” wrote the Los Angeles Times of the ground breaking, “that none of the new Southern California enterprises will …be more certain of financial success. The wheel must have a path of its own between these two cities.”

Tel Aviv wants to put car parking underground

Municipal Director General Menahem Leibe stresses that the city’s investment in bike paths is part of a clearly defined policy of putting bicyclists and pedestrians first. “It can come at the expense of private cars. There’s no such thing as a free lunch,” Leibe said, although he adds that the ultimate goal is striking the right balance among pedestrians, bicycles and cars.

On Bloch Street, one end of which faces the municipality, dozens of parking spaces are being sacrificed for bike lanes, to the outrage of people who live or work in the area. “It’s insignificant,” Leibe said, promising to build more parking lots. He said it’s all part of the worldview of the municipality and the man who heads it.

“Our idea is for vehicles to park underground and for pedestrians and bicyclists to be on the ground. It’s the right thing, especially in a city as densely populated as Tel Aviv,” Leibe said.

Two years ago everybody was talking about Shai Agassi’s idea for electric car charging stations and battery exchange in Israel. Haven’t heard much about that lately.
