In this paper we propose an architecture to supervise and operate platoons of vehicles. The resulting system is mainly composed by a decentralized architecture where each vehicle, equipped with an On Board Unit, collects the fundamental data and forwards them to an operation center that stores and reorganizes them. We focus here on the automatons implemented in each system and we show a first prototype...
In autonomous driving, object tracking is necessary to gather actual information about the object of interest. The longitudinal and lateral controls of automated highway systems need a target object not only to maintain the safety distance between vehicles but also to keep the following vehicle in the same track as the preceding vehicle. So far automated highway systems were only developed for urban...
An intelligent control of the automated highway system for the guidance of four wheeled vehicles is proposed. The control objective is to find one control law that can automatically guide the new-generation smart vehicles when driving in the highway under the effects of uncertain disturbance as wind gust, etc. We successfully propose one control law for designing the intelligent control of four wheeled...
This paper analyzes the present domestic situation of vehicle transportation industry. Because compatibility, high load and exists in the vehicle monitoring system, a solution, based on the .NET Framework 2.0, integration of GPS(Global Position System), wireless communication technology, Microsoft SQL Server 2005 database, Google Maps API V3 and Ajax technology solutions is proposed. The design principle...
With the rapid increase in expressway mileage, accidents and casualties are increasing frequently. Expressway construction in China starts later than developed countries and lack of mature and comprehensive emergency rescue systems. There are some limitations in accident rescue process and information processing such as low coordination level between multi departments and low level of information...
Traffic management is a serious issue in the intelligent transportation systems (ITS). One of the most significant current discussions is traffic incident detection. We have developed an algorithm, referred to vehicle detection based on level set theory and background subtraction, accurate contour of moving object is obtained. The Kalman filtering is applied to predict the possible trajectories of...

In this paper, we propose a novel and simple method for people and vehicles classification in far distance video surveillance. In this approach, moving objects are firstly segmented from background using a background subtraction technique. Secondly, edges of moving objects are extracted using canny operator. Then straight lines of edges of moving objects are extracted by Hough transform and feature...
Today, Intelligent Transportation System (ITS) applications has made a great impact on improving the quality and efficiency of the transportation system. This achievement has attracted researchers to propose more ITS applications, particularly to improve the transportation safety through Vehicular Ad Hoc Networks (VANETs). The major difficulty faced by these researchers is the verification of their...

Road congestion is a common problem worldwide. Intelligent Transport Systems (ITS) seek to alleviate this problem using technology. But most ITS techniques, currently used in developed countries, are inapplicable in developing regions due to high cost and assumptions of orderly traffic. Efforts in developing regions have been few. In this paper, we seek to develop a low-cost ITS technique to detect...
