Washington, D.C. War on Drivers War on People

Ignores ultra dangerous median design for decades where it hangs one of its most profitable speed cameras

The $8 million box sits unmolested but detested beside a pillar in a tunnel that carries four lanes of traffic near the very heart of town. It clicks, it flashes, it clicks, it flashes....
That box and the cameras inside it have generated 61,061 speeding tickets in the past seven months, transferring $8.1 million from the wallets of K Street drivers into the District’s treasury. The cameras, which sit where four lanes of K Street dip under Washington Circle, are on pace to set a District record for cash earned by a speed camera.
If about safety, why are the cameras inside the tunnel rather than at, or pointed towards the nearest traffic light intersection at its approaches, where there are pedestrian crosswalks?

Note the square edged design catches errant automobiles forcing rapid release-dissipation of kinetic energy (and hence increase internal injuries), rather than deflecting such with a smooth guard barrier.

Compare with this video (non embeddable) of the K Street tunnel beneath Washington Circle.


Why are such tunnel-ways not equipped with safer median designs?

Other older such passages have been retrofitted with a guardrail to prevent errant vehicles from getting caught upon a column, hence better dissipating the kinetic energy, reducing injuries.

A schematic drawing provides a view of an early Jersey barrier, but offers no clues to the design’s inventor.

At roughly $1 million monthly from the fines, how about spending some of that money upon installing a smooth continuous jersey barrier application to those square posts beneath Washington Circle?
