This paper introduces a novel method for vehicle speed detection based exclusively on visual information. The proposed system consisting only of a digital camera and a computer is able to identify both the speed of the passing vehicle and its licence plate numbers, which makes it an interesting alternative to existing and expensive photoradar systems. The principle of operation is simple: vehic...

In this paper, we propose an automatic and mechanized license and number plate recognition (LNPR) system which can extract the license plate number of the vehicles passing through a given location using image processing algorithms. No additional devices such as GPS or radio frequency identification (RFID) need to be installed for implementing the proposed system. Using special cameras, the syst...

This paper describes a vehicle detection system based on support vector machine (SVM) and monocular vision. The final goal is to provide vehicle-to-vehicle time gap for automatic cruise control (ACC) applications in the framework of intelligent transportation systems (ITS). The challenge is to use a single camera as input, in order to achieve a low cost final system that meets the requirements ...

VPE is a fully integrated visual heterogeneous parallel programming environment with a message-passing orientation. It is intended to provide a simple human interface to the process of creating message-passing programs. Programmers describe the process structure of a program by drawing a graph in which nodes represent processes and messages ow on arcs between nodes. They then annotate these com...

In existing Cellular Automaton (CA) model, the cellular width is not related to vehicular velocity. However, in real condition, at road’s toll station or intersection, the introduced fixed infrastructure or pedestrians moving into vehicle lane will result in the lane narrowing, so limit the passing speed of vehicle. According to this condition, this paper presents a deformed CA model, and makes...

Vehicular ad hoc networks (VANETs) have emerged as a new powerful technology for data transmission between vehicles. Efficient data transmission accompanied with low data delay plays an important role in selecting the ideal data forwarding path in VANETs. This paper proposes a new opportunity routing protocol for data forwarding based on vehicle mobility association (OVMA). With assistance from...

Vehicular speed has a two-fold influence on traffic accident risk: It affects both probability of involvement and severity of consequence. In terms of involvement, it was long ago suggested that deviation from the mean travel speed of surrounding traffic carried an increased risk fbr the “offending” vehicle.’ A vehicle traveling significantly faster or slower than surrounding traffic is either ...

This paper presents an intelligent traffic light control method based on extension neural network (ENN) theory for crossroads. First, the number of passing vehicles and passing time of one vehicle within green light time period are measured in the main-line and sub-line of a selected crossroad. Then, the measured data are adopted to construct an estimation method based on ENN for recognizing th...

Today, bombing activities are frequently on the agenda. Bomb devices placed under vehicles most common example of activities. Shopping malls, military camps, etc. In places, allowed to pass by checking vehicle with a mirror. This situation may leave door open mistakes that can be made personnel vehicle. this study, an automatic controlled system was designed for passage. It is aimed take under-...
