Post-earthquake road traversability is a critical factor that affects traffic conditions. Therefore, post-earthquake simulation method considering was proposed in this study. First, the impact ranges of earthquake-induced building collapse and fire spread buildings were analyzed, determined accordingly. Subsequently, flow predicted based on characteristics, micro-level vehicle behaviors simulat...

Rosenblueth and Wiener1 stated in 1945, “No substantial part of the universe is so simple that it can be grasped and controlled without abstraction. Abstraction consists in replacing the part of the universe under consideration by a model of similar but simpler structure. Models . . . are thus a central necessity of scientific procedure.” Models can take on many forms ranging from a simple rule...

The lane reversal has proven to be a useful method to mitigate traffic congestion during rush hour or in case of specific events that affect high traffic volumes. In this work we propose a methodology that is placed within optimization via Simulation, by means of which a multi-objective genetic algorithm and simulations of traffic are used to determine the configuration of ideal lane reversal. ...

At some intersections, excessive queue lengths may spill out of the left-turn bay and block the through lanes, jeopardizing level of service for the entire intersection. One of the most effective plans recently presented by the researchers is the "Contraflow left-turn lane" (CLL) In this method, left-turn vehicles will use the nearest lane in the opposite direction in addition to the usual left...

In order to make a social simulation have more realism, it is effective to assign a real human behavior to each agent which makes up the virtual society. In addition, it is desirable to conduct a simulation on as a ...

This paper describes construction of discrete urban traffic simulation model based on NagelSchreckenberg’s cellular automata model (NaSch model) and its modification. These NaSch models have been constructed for simulation of traffic on highways and freeways. We try to modify this aproach to obtain a model of urban traffic. The development is based on an object oriented approach.

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...

One of the major reasons for accidents is speed. Top of Form Inappropriate speed has been identified as the most important causal factor for serious traffic accidents. Traffic calming measures (TCMs) are engineering measures that are widely implemented to improve road safety by considerably reducing vehicle speed. TCMs have been widely used in urban areas to reduce vehicle flow rat...
