When 62 west backs up almost to Crystal Lake Road.
Ever tried using Bunker Hill road to cross Randall heading west?
I hate the idea of a light at Stonegate, but with more lanes and a lower speed limit – it’ll work in the commuters favor.
Steve Willson’s reply:
Below are facts that wouldn’t fit into the Northwest Herald’s 250 word limit for a letter to the editor.
The Highway Capacity manual, published by Transpiration Research Board, has formulas for measuring capacity of roads to handle traffic.
Their formulas show that Randall should be able to handle 1,700 vehicles per hour per lane.
That would be 6,800 vehicles per hour for four lanes.
The County’s figures show that in 2015 that segment of Randall Road had 39,700 vehicles per day north of Algonquin and 38,086 per day south of Algonquin. (Randall Road Traffic Counts at Algonquin Road – Updated, McHenryCountyBlog.com 08/10/16).
First, those numbers are down by about 6% and 10%, respectively, since 2009.
Let us not forget that the original justification for this project in the McHenry County 2040 Long Range Transportation Plan was CMAP’s projections that the County’s population was going to grow at a rate far in excess of the nation’s rate of growth.
Obviously that has turned out to be wrong.
Second, 38,000 to 40,000 vehicles per day is, roughly, 1,600 to 1,650 vehicles per hour, and during rush hour perhaps close to 6,800.
So the numbers from the McHenry County Division of Transportation combined with information in the Highway Capacity Manual published by the Transportation Research Board show that Randall Road is never exceeding its capacity so drastically that we need to spend $97 million to fix the problem.
Finally, “Highway Construction Costs, How Does Illinois Compare”, published by the Economic Policy Institute in May 2014, states “2011 estimates of the generic cost per lane-mile to construct a new divided four lane interstate were $0.92 million for rural Illinois and $1.88 million for urban areas.”
Now, as you accused me of lying, perhaps you’d show your evidence to the contrary, specifically the number of hours per week that the traffic exceeds 6,800 and the amount by which this target is exceeded.
Then perhaps you’d show us evidence that justifies a $97 million price tag,
You might even tell us who you really are.
