When simulating trajectories by integrating time-continuous car-following models, standard integration schemes such as the forth-order Runge-Kutta method (RK4) are rarely used while the simple Euler’s method is popular among researchers. We compare four explicit methods: Euler’s method, ballistic update, Heun’s method (trapezoidal rule), and the standard forth-order RK4. As performance metrics,...

Dit proefschrift is goedgekeurd door de promotoren: " To me it is of very little importance whether they [Masters] exist or whether they do not exist, because when you have to walk to the camp or to the station from here, there are people ahead of you, nearer the station, people who have started earlier. What is more important – to get to the station or to sit down and worship the man who is ah...

†Department of Mechanical Engineering, University of Michigan, Ann Arbor, MI 48109, USA An errorable car-following driver model is presented in this paper. An errorable driver model is one that emulates human driver’s functions and can generate both nominal (error-free) as well as devious (with error) behaviors. This model was developed for evaluation and design of active safety systems. The ca...

Visual angle car following models assume fixed values (thresholds) for the angular velocity (∆Ө/∆t) over which the driver of the following vehicle is affected by the leading vehicle. This paper explains the advantages and limitations of such models and provides possible solutions for these limitations. Sensitivity analysis has been carried out for these purposes as a part of this paper. It was ...

In this paper a control system has been designed to improve traffic conditions in car following maneuver. There are different methods to design a control system. In this paper design approach is based on the Fuzzy sliding mode control (FSMC) system. The aim of designing FSMC system is to achieve safe and desire longitudinal distance and less lateral displacement. In orde...

INFARCTION IN THE VERTEBRO-BASILAR artery distribution has been noted in a variety of circumstances associated with head turning and hyperextension of the neck, but the interval between the trauma and the cerebrovascular stroke is usually short. This paper describes a patient who developed a cerebellar infarction five weeks following a car accident, an unusually long delay which deserves mentio...

In this paper, we present a full velocity difference model for a car-following theory based on the previous models in the literature. To our knowledge, the model is an improvement over the previous ones theoretically, because it considers more aspects in car-following process than others. This point is verified by numerical simulation. Then we investigate the property of the model using both an...

In this paper ten microscopic traffic flow models of very different kind are analysed concerning the correct reproduction of the car-following behaviour on single lane roads. The models are calibrated and validated with data collected via DGPSequipped cars (Differential Global Positioning System) on a test track in Japan. The positions of the cars are delivered every 0.1 second with very high a...

An adaptive fuzzy logic controller is described which assists the driver in vehicle speed and distance control by offering a driving strategy via an active accelerator and brake pedal. In order to be accepted by the driver, the behavior of the system called ACC (Adaptive Cruise Control) has to meet the expectations of the human driver to a certain degree. The Fuzzy-ACC provides separate control...

A general class of car-following models is studied with different driver reaction time configurations. In particular the stability of traffic flow is investigated in case of human-driven vehicles and computer-controlled (robotic) cars. It is shown that in both cases, time delays can change the frequency of arising oscillations and, consequently, the wavelength of the emerging traveling waves, l...
