Congratulations: Missouri DOT Diverging Interchange

Missouri must be given KUDOS for their courage to think outside the box. We have seen other efforts like this but this one finally hits home as a serious retrofittable interchange solution.

I-44/Route 13 Interchange
Diverging Diamond Design

Most interchanges resemble large paring lots with gates and once the demand exceeds capacity the excess backs up onto to the interstate, causing accidents, flow chaos and destruction of flow capacity.
This solution improves every aspect flow demand while reducing the conflict zones, because the excess demand for the surface streets can mitigated for, thereby minimizing overflow demand from building up on the interstate.
We have a solution to enhance guidance and further reduce possible confusion, day or night; nonetheless YES.

By the Numbers: Gross safety distortions go mainstream.

The Oregon Department of Transportation and State Police initiated a propaganda blitz based on invented data to garner support for Oregon’s speed laws and increased OSP staffing. Release inferred 49 percent of their highway fatalities where caused by speed in excess of the posted limit; whereas, its data shows it to be 8.5 percent if you accept their procedures, we don’t, and less than 1 percent of the state’s attributed cause for all accidents.

Oregon State Police - Speed was a contributing factor to this fatal crash on U.S. 26 near Elsie on July 20.

Speeders killed more Oregonians than drunken drivers in 2008, according to a new study showing that the state far outpaces the rest of the nation when it comes to deaths caused by heavy-footed motorists. PDF version

PSA Most Effective

This PSA in the UK is the prefect example of an effective deterrent for young drivers on distracted driving. But the term distracted driving is such a broad category that laws against distracted driving will not only fail, they become onerous and the enforcement abuses are incompatible with a free society. Being Distracted while operating trains, busses etc should be outlawed per se but advancing computer technology interfaces and aids are also our best safety hope for the future.

Attention getting PSAs work, turning human activity into a crime against the state will fail.

USDOT Distracted and Operating Under the Influence

The United States Department of Transportation has seriously compromised safety by allowing itself to be distracted while "operating under the influence" of special interest groups. This diversion from its safety charter is directly contributing to an incredible number of lives lost, injuries and financial mayhem for many millions more. PDF version Read More...
