OVERTAKING RATES ON LOW VOLUME ROADS

The operation of a diverse vehicle fleet gives rise to increased traffic interactions due to motorists wishing to overtake. The model developed in this paper gives a simple method of estimating the rate with which faster vehicles catch-up to slower vehicles. It relates catch-up rates and overtaking rates on a homogeneous road section with vehicles travelling at constant speeds and with uniform flows along the section to traffic flows and speed parameters. The model is only applicable to roads with low traffic flows, say less than 150 veh/h, as it is assumed that the time drivers spend following other vehicles before overtaking is small in comparison with the journey time and that catch-up rates can be equated to overtaking rates. The model can be used as a tool for the selection of appropriate routes for long vehicles and for the calculation of passenger car equivalents using the Walker method (A). The number of the covering abstract of the conference is TRIS no. 368448. (TRRL)
