This paper presents an accurate and efficient traffic state detection system that is implemented on smart cameras. Our video analysis method employs feature tracking and edge information along with the camera calibration parameters for periodic level of service (LOS) measurements. After a calibration using the known lengths of lane markings, the smart cameras perform the LOS estimation onboard ...

Due to the rapid advancements of computing, telecommunication and control technologies, the use of Transportation Information System (TIS) has become very popular. Under such system, the public would be able to obtain traffic and transport information in real time through private or public service providers via various means such as variable message signs, Internet, and mobile phones, etc. The ...

Based on ideas from the literature and the project team, several reasonable interface options were prototyped using SuperCard (on a Macintosh computer). Some designs were eliminated after initial prototype attempts because critical details were not legible. Others were developed further and evaluated using human factors computational methods (GOMS, Tullis Display Analysis Program) and quick usa...

With the increasing demand for air transportation, all parties involved in the air transportation system have increased their efforts to make the system more efficient without sacrificing safety. This paper presents a new system based on information integration, the Air Traffic Control Command Monitoring System (ATCCMS), which integrates all kinds of fundamental information such as radar inform...

Currently, traffic congestions are common events in road networks of main cities in developing countries. It has been observed that, the size of congestion increases year after year. For traffic congestion management to work efficiently, sufficiently and accurately information are needed. In this research we present an alternative method using agent technology to collect and manipulate data so ...

Over the last few years, vehicular ad hoc networks (VANETs) have gained popularity for their interesting applications. To make efficient routing decisions, VANET routing protocols require road traffic density information for which they use density estimation schemes. This paper presents a distributed mechanism for road vehicular density estimation that considers multiple road factors, such as r...

A prototype geographic information system (GIS) for the analysis of motor vehicle collisions in Honolulu, Hawaii, is described. An overview of GIS hardware and software is provided along with criteria utilized in the development of the Hawaii system. Mapping and spatial data sources relevant to traffic safety are described and evaluated. The usefulness of Census Bureau Topologically Integrated ...
