This research has been conducted to discover the correlation between side friction factor (demand) and longitudinal grade which is located in horizontal curves in three-dimensional simulation model. In this way, we present a series of models in order to assess these factors based on design speed, longitudinal grade, and vehicle type (Sedan, SUV, and Truck). The research involves (1) conducting a series of multi-body simulation tests using CarSim and TruckSim, (2) multiplex regression analysis to acquire relations between variables, and (3) recommending models for the side friction factor. Based on the results, side friction factors (demand) are bigger than downgrades for all vehicle types when cornering. Another important result is the significant differences of side friction factors for passenger cars in compared to heavy vehicles.
