calculations of steepness for hill climbs

see also map of NJ hill areas | details on selected climbs | Hudson Valley NY climbs

I calculated steepness and size for some hills on New Jersey roads. There's some complications in this, and I'm confident there's some significant inaccuracies in this list . . . anyway here's my results so far as of October 2007:

Warning: Some of these climbs often have high motor vehicle traffic through a bad visibility section, others have damaged surface or other dangerous conditions. The table above is only an estimate of size and steepness of each hill, not a recommendation to attempt climbing or descending it.

Notes

? = traffic, visibility, and surface characteristics unknown to me.

H = higher traffic volume than many other climbs.

V = questionable visibility or limited sight distance.
