Identification of the behavior of the drivers that have used amphetamines in car following procedure applying the adaptive neuron fuzzy method

In recent years, consumption of stimulant substances compared to alcohol and drugs has been very popular, but still vast investigation on the impact of the stimulant substance abuse on the driving behavior has not been conducted.This article provides a method to identify the behavior of drivers that have used amphetamines. In this method, 16 healthy professional Scania bus drivers and as many as 6 drivers addicted to amphetamines in the Nasir Scania bus driving simulator have been examined and performed practical tests. The scenario chosen for the driving in the simulator was of the “car following” type. In order to analyze the behavior of healthy drivers and the ones addicted to amphetamines, the delay time for each driver and some other safety factors such as the time to collision, THDW, unsafe density, and also the longitudinal distances between the leading and the following car were collected using variables taken from the driving simulator. Then an adaptive neuro fuzzy inference system (ANFIS) has been designed to separate information for healthy people and addicted to amphetamines. Finally, the driving behavior evaluated using GHR model and the then compared to the performance of the designed ANFIS system. The result shows that the designed ANFIS system has a performance much better than GHR model and can distinguish between the amphetamines addicted drivers and healthy one and identify them with the accuracy of 97%.
