NONLINEAR TRUCK FACTOR FOR TWO-LANE HIGHWAYS

A microscopic simulation model for traffic flows on two-lane, two-way highways was developed to include all important factors known to affect these flows. This simulation provided results in agreement with field data and was applied to flows in level terrain, in rooling terrain, and on sustained grades. Results from the model indicated that the truck factor, currently of linear form, should be nonlinear. A nonlinear form was derived and successfully applied to summarize results for a variety of terrains and vehicle populations. This paper presents a brief description of the simulation, the evidence for a nonlinear truck factor, and the derivation and testing of the nonlinear factor. /Author/
