The similarity of the evolution of human languages (or alphabets , bird songs, ...) to biological evolution of species is utilized to study with up to 10 9 people the rise and fall of languages either by macroscopic differential equations similar to biological Lotka-Volterra equation, or by microscopic Monte Carlo simulations of bit-strings incorporating the birth, maturity, and death of every ...

Traffic simulation is a valuable tool for the design and evaluation of road networks. Over the years, the level of detail to which urban and freeway traffic can be simulated has increased steadily, shifting from a merely qualitative macroscopic perspective to a very detailed microscopic view, where the behavior of individual vehicles is emulated realistically. With the improvement of behavioral...

For our contribution we describe the extension of a microscopic model for pedestrian simulation that introduces hybrid navigation strategies based on graphs. To do so, we introduce a navigation graph layer serving as the basis for different routing algorithms to map individual pedestrian behaviours. The automatic generation of a reduced visibility graph to be used as a navigation graph is descr...

Most of today’s ADASs rely on the data of local perception sensors. With the introduction of Vehicle-to-X (V2X) communication, the perception range of next generation vehicles will be extended even further. In addition to the introduction of local perception sensors in Veins, we present ArteryLTE, a holistic simulation environment for using the vehicle position data from the microscopic traffic...

It is shown that a traditional travel demand forecast combined with a simulationbased approach can serve as a short-term forecast for the traffic situation. The approach presented was developed and tested during the Soccer World Cup 2006 in the city of Cologne as a service for the action forces to react as fast as possible to developing aberrations. This paper discusses the merits and the short...

The current understanding of how receptors diffuse and cluster in the plasma membrane is limited. Data from single-particle tracking and laser tweezer experiments have suggested that membrane molecule diffusion is affected by the presence of barriers dividing the membrane into corrals. Here, we have developed a stochastic spatial model to simulate the effect of corrals on the diffusion of molec...

When microscopic traffic simulation is used to predict the traffic jam and to evaluate the transportation planning program, the speed of simulation is important. In the distributed microscopic traffic simulation system (DTMS), the configuration of terminals is not only the key to ensuring the speed-up of the simulation, but also the basis of reducing the cost of the simulation. In this paper, w...

0-7803-7952-7/03/$17.00  2003 IEEE. Abstract This paper discusses the problem of modelling and simulation of traffic systems, and presents the traffic simulator SITS (Simulator of Intelligent Transportation Systems). The SITS is based on a microscopic simulation approach considering different types of vehicles, drivers and roads. A dynamical analysis of several traffic phenomena is then addres...

Traffic simulation plays an important role in the evaluation of traffic decisions. The movement of vehicles essentially is the operating process of drivers, in order to reproduce the urban traffic flow from the micro-aspect on computer, this paper establishes an urban traffic flow microscopic simulation system (UTFSim) based on multi-agent. The system is seen as an intelligent virtual environme...

For the simulation of pedestrians a method is introduced to find routing alternatives from any origin position to a given destination area in a given geometry composed of walking areas and obstacles. The method includes a parameter which sets a threshold for the approximate minimum size of obstacles to generate routing alternatives. The resulting data structure for navigation is constructed suc...
