On-road emissions are precisely the emissions which are impacting the air quality and which need to be controlled if air quality improvements are desired. Remote sensing measures mass emissions of CO, HC, NO and smoke per kg (or per L) of fuel burned. On-road emissions are not certification emissions for new vehicles, although new vehicles measured on-road most often provide remote sensing read...

BACKGROUND Daytime running lights (DRLs) are a safety feature intended to reduce crashes by increasing the contrast between vehicles and the background. AIMS The purpose of this study was to determine whether there is an association between vehicles in the USA being equipped with DRLs and crash rates. METHODS This was a retrospective study using the Minnesota Department of Transportation (M...

Background: In large cities, the share of vehicles in air pollutants emissions is nearly 70% that is mainly due to use of fossil fuels. Environmental simulation has many advantages such as accuracy and speed of modeling. Present study was conducted to create a model of air pollution [Carbon Monoxide (CO) and Nitrogen Oxides (NOx)] from vehicles in fifty following years, in Mashhad. Methods: Acc...

A stereo vision based vehicle/obstacle detection system has been proposed that generates alarms when vehicles/obstacles are detected in vicinity of near/mid region. Numerous techniques have been applied to detect vehicles/obstacles using a forward facing monocular camera mounted inside a vehicle. This paper presents a methodology for vehicle/obstacle detection using high resolution stereo camer...

Generally, vehicles’ stop-and-go driving will consume more fuel and emit more co2 than constant speed of vehicles .To reduce vehicles’ CO2 emissions vehicles’ travel should be smoothed by reducing the stop-and-go times. In this paper, three techniques are proposed to realize dynamic traffic light control for smoothing vehicles’ travel. In technique-1, an intelligent transportation system (ITS) ...

Vehicular ad hoc network (VANETs) is a special class of MANET’s which uses vehicles as a mobile node for the data dissemination. It uses Intelligent Transportation System (ITS) in which vehicles can communicate with each other to avoid large number of increasing accidents on roads. Such a system enables vehicle to vehicle and vehicle-to-infrastructure communication and provides vehicles with up...

Transferring data between the ocean surface and an operating Autonomous Underwater Vehicle (AUV) is a difficult and slow process. Current methods of un-tethered submersible communication have either a very limited data transfer rate or a prohibitively short range. In this paper, students of the University of Florida propose a new data transfer method that will supply the high data rates of a te...

The motive of this paper is to design and implement “Intelligent Traffic with Emergency Control and Stolen Vehicle Tracking System” using Artificial Intelligence. Thus this system is capable to sense the density of vehicles for intelligent traffic management and also able to recognize emergency vehicles as ambulance to allow that signal for emergency control, as well as this system also recogni...
