Posted by jrf2 on Thu Aug 2 08:15:47 2012, in response to Re: Wheel detectors, posted by G1Ravage on Thu Aug 2 05:01:25 2012. Something happened on the original post - if it suddenly shows up, please forgive the repost !!I am assuming that the speed is determined by the time between the frist and second axles on a car. I won't worry about the second axle on one car to the first axle on the next for now. In div B, there can be multiple classes of cars which will have different distances between the axles 1 - 75 foot cars 2 - 60 foot cars 3 - 54 foot cars (div A cars - yard moves, work trains etc. 4 - other equipment (desiels etc). How are their distances handled. A 54 foot car passes a point much faster (time wise) than a 75 footer which would cause a higher speed calculation. |
