Modelling of acceleration and deceleration characteristics of vehicles

Models of acceleration and deceleration characteristics of vehicles are essential for many traffic engineering applications. Many researchers have represented the acceleration characteristics by means of constant values or simple equations, but these are unrealistic. Zero jerk acceleration models, which are considered to be realistic, seldom reflect the driver behaviour. This paper presents the development of acceleration and deceleration models that reflect the driver behaviour for various classes of vehicles in mixed traffic. The data required for the study was collected using photographic method. Regression models of average acceleration/deceleration in terms of speed revealed that average acceleration decreases with increase in speed, where as, the deceleration increases with an increase in speed. The component of the models that represent the driver behaviour was found to follow normal distribution.
