Car following process is time-varying in essence, due to the involvement of human actions. This paper develops an adaptive technique for car following modeling in a traffic flow. The proposed technique includes an online fuzzy neural network (OFNN) which is able to adapt its rule-consequent parameters to the time-varying processes. The proposed OFNN is first trained by an growing binary tree le...

The development of new protective systems must be performed on reliable tools and representative of alive human. In an earlier study a simplified and realistic model of the head-neck system under moderate rear impact was performed. It is clear and often addressed in the literature that under such an impact configuration, the deformation of the torso and the car seat, is of extreme importance an...

This paper presents an optimal vehicle and seat suspension design for a half-car vehicle model to reduce human-body vibration (whole-body vibration). A genetic algorithm is applied to search for the optimal parameters of the seat and vehicle suspension. The desired objective is proposed as the minimization of a multi-objective function formed by the combination of seat suspension working space ...

The purpose of designing the active suspension systems is providing comfort riding and good handling in different road disturbances. In this paper a novel control method based on adaptive neuro fuzzy system in active suspension system is proposed. Choosing the proper data base to train the ANFIS has an important role in increasing the suspension system’s performance. The data base which is used...

Recently, passenger comfort and user experience are becoming increasingly relevant for the railway operators and, therefore, manufacturers as well. The main reason this to happen is that a clear differential value considered by passengers final customers. Passengers’ directly related accelerations received through car-body of train. For reason, suspension damping components must be maintained i...

The theory of a jamming transition is proposed for the homogeneous car-following model within the framework of the Lorenz scheme. We represent a jamming transition as a result of the spontaneous deviations of headway and velocity that is caused by the acceleration/braking rate to be higher than the critical value. The stationary values of headway and velocity deviations and time of acceleration...
