A Traffic Kinetic Model Considering Desired Speed

In this paper, the desired speed variable is introduced into the ‘table of games’ and a new ‘table of games’ and corresponding traffic kinetic model are then formulated. The hybrid programming technique of Visual Basic for Applications (VBA) and MATLAB is used to develop the computational engine for the proposed model. The study focuses on the effect of desired speed on the speed-density curve. With one desired speed, the relationship between average speed and density is investigated under different road conditions and desired speeds. With multiple desired speeds, an investigation is carried out on the effect of the coefficient of variation on average speed, and the effect of percentage of low desired speed vehicles on average speed. An important factor influencing average speed is the variation of the desired speed. When density is low, traffic flow is in an individual flow pattern, and the average speed of the traffic flow is determined by the variation of the desired speed. When density is high, traffic flow is in a collective flow pattern, and the average speed is determined by density.
