This article presents one solution to the parameterization problem for automated road feature extraction models. Using a line-length buffer approach, a measure of agreement between extracted road features and reference road features is defined. An automated approach for deriving this agreement index is presented and implemented as a parameterization model. Coupling the implemented parameterizat...
This paper studies the modeling theories and simulation methods for railway transportation system. The railway transportation system is a typical temporal-spatial dynamic system. Recently the method with temporal-spatial computation characteristics, Cellular Automata, is often used for road traffic flow research, but it’s homogeneity restricting make it impossible to modeling railway transporta...
Intelligent transport systems have efficiently and effectively proved themselves in settling up the problem of traffic congestion around world. The multi-agent based transportation system is one most important intelligent systems, which represents an interaction among neighbouring vehicles, drivers, roads, infrastructure vehicles. In this paper, two management models been created to mitigate en...
Advancement of the motor vehicle and its production methods is analyzed as a process of technological change. In a broader context, motor vehicles evolved as an integral component of road transportation through a series of interlaced substitutions of old by new technologies. Building on a large number of studies that described technological substitution processes, first it is shown how new ener...
Annually, more than 1 million people were killed in road traffic accidents worldwide every year and an uncounted number were severe injured. In 2012 fatal injuries caused by road traffic accidents are under the top ten lists of causes of death in the world. It´s expected that in the near future road traffic accidents become one of the main causes of death in the world. Most of these fatal injur...
