    a sudden speed drop in the leader vehicle of vehicle platoon results in propagating the deceleration wave from downstream towards the upstream flow. points of wave propagation of the leader vehicle towards the follower vehicle identification are done based on newell’s theory in trajectory data. deceleration wave propagates based on two parameters, time and space, τ- δ. a follower driver performs different behavioural reactions that they result in deviating follower driver from newell’s trajectory. in this paper, follower driver behaviour was identified based on two theories. the asymmetric microscopic driving behaviour theory and traffic hysteresis were used during the deceleration and acceleration phases, respectively. the data trajectories were classified into different traffic phases. driver’s parameters were identified at the microscopic level. since the follower driver had the nonlinear behaviour, artificial neural networks were developed. they were able to analysis and identify effective parameters of dependent variable between deceleration phases leading to congestion phase, based on the behavioural patterns. analysis results present effective parameters based on any behavioural patterns. spacing difference of two phases, deceleration and congestion phases, was the most effective parameter of both two behavioural patterns, under reaction – timid and over reaction – timid. increasing the spacing difference of two phases results in decreasing (increasing) time based on under reaction – timid (over reaction – timid).
