GA1 5 6m e type GA2 7 8m Height setting can be parameter with the command H Interlane For installations where several lanes are monitored one TMS NET by lane it is important to understand that vehicles driving between two lanes can be detected by two TMS NET simultaneously as seen in figure TO DO To achieve the best counting precision it is necessary to take these inter lanes cases into account at the node collecting the data of the detectors Top view This vehick will be seen by the two detectors It is possible to tune the importance of this phenomenon by adjusting the installation to change the detection zone width installing the TMS NET higher or with a tilt angle closer to the horizontal will widen the detection zone width and inversely lowering the installation height or setting the tilt angle closer to the vertical will reduce the detection zone width These adjustments must be done carefully if the detection zones widths are too narrow small vehicles driving just between two zones could pass undetected Side installation This installation type is not advised by Icoms as you cannot separate accurately different traffic lanes e Distance command D 14 Distance between installation pole and the vehicles movement axis for uni directional detection Height of installation command H Recommended height of installation Type GA1 5 6m Type GA2
