This paper studies the effects of back step movement and update rule on the traffic congestion properties of mobile objects, using computer simulation. The mobile objects are modeled as four-way-biased random walkers in two-dimensional square lattice. It is found that there is always a phase...

Traffic congestion in point-to-point movement is studied using four simple traffic models. The four traffic models studied are movement between randomly chosen starting and destination points, back and forth movement between same two points, movement with preference of horizontal and vertical...

This paper studies congestion avoidance in a simple two-dimensional traffic system, using computer simulation. The mobile objects avoid congestion among themselves using simple congestion-avoiding traffic rules. The objects adaptively avoid congested regions and move towards less congested...

In narrow waterways, closed ships might interact due to hydrodynamic forces. To avoid clashes, different lane-changing rules are required. In this paper, a two-lane cellular automata model is proposed to investigate the traffic flow patterns in narrow water channels. Numerical experiments show...

We study the process of evacuation of pedestrians from the room with the given arrangement of doors and obstacles by using the cellular automata technique. The technique which became quite popular is characterized by the discretization of time as well as space. For such a discretized space we...

To better understand the characteristics of car–truck heterogeneous traffic flow that is very common on freeway, a cellular automata-based traffic flow model is proposed for single lane traffic in this paper. The proposed model discriminates the four types of car–truck following combination,...

Knowledge of occupant evacuation process in a building presents engineers with an efficient way of testing the rationality of the building design before construction. Meanwhile, it benefits to the occupant casualty estimation in the building under earthquakes, which has been an essential problem...

We introduce a stochastic model to study the problem of time evolution and outcome of simple two-party competitions or battles on a lattice where each party randomly deploys its constituents or elements to the lattice. The elements have assigned strength levels that determine how competitive or...

The understanding of traffic dynamics on highway networks is essential for traffic control. Nowadays realistic microscopic models exist that allow highly efficient (faster-than-real-time) simulations of large networks. These simulations can be used not only to determine the state of the network...

A simulation of bi-direction pedestrian flow based on cellular automata (CA) will be presented from two aspects: direction split and pedestrians’ walking habit in this paper. The simulation uses Dynamic Parameters Model (DPM) to simplify tactically the decision-making process of pedestrians in...
