Spatial patterns of various criteria air pollutants, like SO2, NO2, O3, and TSP were studied at Shahdara National Ambient Air Quality Monitoring station in Delhi (India) in July 1999. The minimum pollutant concentrations were observed during morning hours, whereas the highest concentrations were found during the late night hours, which seem to be related with the vehicular emission. Pre-monsoon...

Vehicular ad hoc network (VANET) is one of the largest areas of interest in wireless technology because it provides very wide variety of services in the field of transportation. Intelligent Transportation System (ITS) provides a set of standards for Vehicular Communication networks. The vehicular network provides many useful applications and advantages. The multimedia applications, which are ba...

In this paper, we illustrate a Mobile Wireless Vehicular Environment Simulation (MoVES) framework for the parallel and distributed simulation of vehicular wireless ad hoc networks (VANETs). The proposed framework supports extensible, module-based and layered modeling, and scalable, accurate and efficient simulation of vehicular scenarios integrated with wireless communication and mobile service...

In recent time, the standards for Vehicular Ad-hoc Networks (VANETs) and Intelligent Transportation Systems (ITSs) matured and scientific and industry interest is high especially as autonomous driving gets a lot of media attention. Autonomous driving and other assistance systems for cars make heavy use of VANETs to exchange information.They may provide more comfort, security and safety for driv...

Vehicular networks aimed toward providing roadside services such as traffic alerts, estimated time to reach a destination, alternative routes, and in general improve the efficiency and safety on the road are emerging in both the United States and Europe. Information exchange in such networks occurs between vehicles (inter-vehicle communications) in an ad hoc manner and also with roadside base s...

$EVWUDFW2 Vehicular networks are promising in providing Vehicle-to-Infrastructure (V2I) and Vehicle-to-Vehicle (V2V) communication, thus allowing for several useful services on roads related to safety applications as well as entertainment applications. However, a number of constraints can impact the reliability of vehicular networks applications. The general constraints concern the high mobilit...

The vehicular cloud is a promising new paradigm, where vehicular networking and mobile cloud computing are elaborately integrated to enhance the quality of vehicular information services. Pseudonym is a resource for vehicles to protect their location privacy, which should be efficiently utilized to secure vehicular clouds. However, only a few existing architectures of pseudonym systems take fle...

The vehicular flow in the urban street canyon is considered. The classical field description is used in the modelling of the vehicular movement and of gaseous mixture in generic urban street canyon. The dynamical variables include vehicular densities, velocities, and emissivities: of pollutants, heat and exhaust gases, as well as standard mixture components' variables: densities, velocities, te...

A general proecological urban road traffic control idea for the street canyon is proposed with emphasis placed on development of advanced continuum field gasdynamical (hydrodynamical) control model of the street canyon. The continuum field model of optimal control of street canyon is studied. The mathematical physics approach (Eulerian approach) to vehicular movement, to pollutants’ emission an...

Experiments on air and biomonitoring were conducted to evaluate pollution impact on the vegetation along the road in Jalgaon City, Maharashtra. The plantation along the roads and mainly includes neem (Aadirachta indica), peepal (Ficus religiosa), banyan (Ficus benghalensis), almond (Terminalia catapa). For biomonitoring, leaf area, total chlorophyll, plant protein were analyzed to study the imp...
