Implementation of highway-rail level crossing warning systems, educational programs and research on crossings have all contributed to a steady reduction in the risk of level crossings to North American highway users over the past several decades. Much less attention has been given to understanding the effect of level crossings on train safety and risk. Incidents at highway-rail level crossings ...

A new algorithm to eliminate moving cast shadow for robust vehicle detection and extraction in a vision-based highway monitoring system is investigated in this research. The proposed algorithm is based on a simplified 2D vehicle/shadow model of six types projected to a 2D image plane. Parameters of the joint 2D vehicle/shadow models can be estimated from input video without the light source and...

Due to the increasing demand for traveling in public transportation systems and increasing traffic of vehicles, nowadays vehicles are getting to be intelligent to increase safety, reduce the probability of accident and also financial costs. Therefore, today, most vehicles are equipped with multiple safety control and vehicle navigation systems. In the process of developing such systems, simulat...

The merging process in an Automated Highway System (AHS) is divided into a speed adjustment stage and a lane merging stage. Three important parameters, namely, acceptability, availability and pursuability, are analyzed to characterize the AHS lane gap features for the ideal, smooth and safe merging of the ramp vehicles. Three control guidance laws, namely, linear, optimal and parabolic speed pr...

The license plate recognition system is part of the intelligent transportation system. In the intelligent transportation system, the vehicle image is used as the system input. The first step is to improve the image, after the edge detection, a series of morphological operations are performed to identify the plaque. The main purpose of this research was to increase the importance of plate re...

Traffic safety applications using vehicle-to-vehicle (V2V) communication is an emerging and promising area within the intelligent transportation systems (ITS) sphere. Many of these new applications require real-time communication with high reliability, meaning that packets must be successfully delivered before a certain deadline. Applications with early deadlines are expected to require direct ...

Improving motor carrier and highway safety is a primary focus of many transportation agencies in Canada and the U.S. With the decreased building of new infrastructure, and the rapid growth of trucking activity in the two countries, it is important to develop innovative ways to improve highway safety as it relates to commercial vehicles. Due to the nature of trucking in the Canadian Prairie regi...

In this paper, we report on the design of a protocol for transparent, location-independent access in mobile systems. The protocol, termed by us Mobile Client/Server Protocol (MCSP) is an implementation of a communication layer on a mobile host and a stationary machine within the wireline network, and provides middleware functionality. The MCSP supports communication services through the client/...
