Interesting to know about the different gizmos competing for the Highway Department dollars, but I think the article ignores the abysmal failure that the looney HOV/toll lanes have been, at least locally. As I recall, the 394 boondoggle, that created 3 of the worst bottlenecks in the State the day it opened, was the original looney-laned project in Minnesota. And ever since it opened, MnDOT has continued pouring money down the 394 drain in a futile attempt to fix the mess it created. As everyone knows, and no one should be surprised, the fixes, whether screwball “zipper lanes” or maniacal overhead signage or outrageously expensive and soon obsolete vehicle spying “transponder” systems, are never an improvement, and inevitably result in spending more money fixing the mess that the previous “fix” only exacerbated. Rather than giving us the lowdown on all the latest and greatest toll road technology, maybe you could fill us in on the money spent thus far on the MnPASS/HOV/transponder system “fixes” and the toll revenue collected as a result. My guess is the cost of the MnPASS/HOV/transponder system technology has thus far far surpassed any revenue that the technology has generated.
