A self-organizing feature map (SOM) was used to represent vehicle-following and to analyze the heterogeneities in vehicle-following behavior. The SOM was constructed in such a way that the prototype vectors represented vehicle-following stimuli (the follower's velocity, relative velocity, and gap) while the output signals represented the response (the follower's acceleration). Vehicle trajector...
car body lightening and crashworthiness are two important objectives of car design. due to their excellent performance, composite materials are extensively used in the car industries. in addition, reducing the weight of vehicle is effective in decreasing the fuel consumption. hat shape energy absorber is used in car’s doors for side impact protection. the aim of these numerical models and exper...
1 Heterogeneity is an essential characteristic in car-following behaviors, which can be defined 2 as the differences between the car following behaviors of driver/vehicle combination under 3 comparable conditions. This paper proposes a Visual Imaging Model (VIM) with relaxed 4 assumption on a driver’s perfect perception for 3-D traffic information and uniform reaction 5 to vehicles with differe...
The advancement of in-vehicle sensors provides abundant datasets to estimate parameters car-following models that describe driver behaviors. question parameter identifiability such (i.e., whether it is possible infer its unknown from the experimental data) a central system analysis question, and yet still remains open. This article presents both structural practical on four common models: i) co...
Adaptive Intelligent Tutoring Systems (ITS) aim at helping students going through the resolution of a given problem in a principled way according to the desired outcomes, the intrinsic capabilities of the student, and the particular context in which the exercise takes place. These systems should be capable of acting according to mistakes, boredness, distractions, etc. Several works propose diff...
We present a traffic model that extends the linear car-following model as well as the minplus traffic model (a model based on the min-plus algebra). A discrete-time car-dynamics describing the traffic on a 1-lane road without passing is interpreted as a dynamic programming equation of a stochastic optimal control problem of a Markov chain. This variational formulation permits to characterize th...
This study aims to improve the desired distance adaptability of cooperative adaptive cruise control (CACC) during car-following. In this study, characteristics in different traffic flow states were analyzed. The general functional form car-following process was formulated. Then, a platoon constructed compare effect under conditions, using following speed and lead vehicle disturbance, as observe...
