In recent years the modelling of traffic flow using methods from statistical physics, especially cellular automata models have allowed simulations of large traffic networks faster than real time. In this paper, we study a probabilistic cellular automaton model for microsimulations of traffic flow of automated vehicles in highways. This model describes single-lane traffic flow on a ring. We stud...

The interplay between discrete and continuous dynamical models is discussed, and a systematic approach to developing and combining these models together is outlined. The combination is done with linking predicates that define refinement relations between the models. As a case study, we build an abstract, discrete spatial model and a concrete, continuous dynamic model for traffic manoeuvrers of ...

The study and observations of innovative portable roadside sensing system are done for the increasing number of losses in human live and also finance due to traffic accidents. The aim of this system to provide an efficient solution for automatic vehicle parameters measurement system. The wireless anisotropic magnetic sensor system embedded next to the roadway and examines the adjacent lane traf...

The Nagel-Schreckenberg model is a simple cellular automaton for a realistic description of single-lane traffic on highways. For the case vmax = 1 the properties of the stationary state can be obtained exactly. For the more relevant case vmax > 1, however, one has to rely on Monte Carlo simulations or approximative methods. Here we study several analytical approximations and compare with the re...

Communication of information from the roadway infrastructure to vehicles is expected to enhance Automated Highway Systems (AHS) by supporting subsystem functions like vehicle motion control, multiple vehicle coordination, and vehicle navigation. A suitable communication channel is information coding in the lateral reference used for automatic steering and lane keeping control, e.g. in the magne...

The interest in in-vehicle Advanced Driver Assistance Systems (ADAS) is increasing. New systems such as Adaptive Cruise Controls and Collision Avoidance Systems are currently introduced at a rapid pace. To exploit the full potential of these systems it is necessary to estimate the systems future impact already at early development stages. This paper introduces a traffic simulation framework for...

Highway management systems are used to improve safety and driving comfort on highways by using control strategies and providing information and warnings to drivers. They use several strategies starting from speed and lane management, through incident detection and warning systems, ramp metering, weather information up to, for example, informing drivers about alternative roads. This paper provid...

In the Nagel-Schreckenberg model of vehicular traffic on single-lane highways vehicles are modelled as particles which hop forward from one site to another on a one dimensional lattice and the inter-particle interactions mimic the manner in which the real vehicles influence each other’s motion. In this model the number of empty lattice sites in front of a particle is taken to be a measure of th...

Authors: Yunpeng Zang (Member IEEE), Bernhard Walke (Fellow IEEE), Guido Hiertz (Member IEEE), Christian Wietfeld (Senior Member IEEE) Abstract: The Decentralized Congestion Control (DCC) algorithms specified in ETSI ITS standards [1] address the IEEE 802.11p MAC and provide reliability of periodic broadcast messages at high density of vehicles. However, the deterministic relation between contr...
