MATHEMATICAL CORRECTION OF AXLE UNDERCOUNTING IN PNEUMATIC TUBES TRAFFIC SURVEYS

This is a report on mathematical correction of undercounting of axles by pneumatic tube traffic counters on multilane roads. The strategem is based on estimating the shadow of counter inactivity presented to other lanes when an axle goes over a pneumatic tube in a given lane. The assumptions that justify the analysis are listed. Forumlas are presented that have have been checked by simulation. In the case of pulsed traffic, special computations are necessary to account for the traffic volume incrementally.
