Transportation activities can contribute to accumulation of heavy metals in roadside soil and grass, which could potentially compromise public health and the environment if the roadways cross farmland areas. Particularly, heavy metals may enter the food chain as a result of their uptake by roadside edible grasses. This research was conducted to investigate heavy metal (Cu, Zn, Cd, and Pb) conce...

accidents. To overcome this issue, Vehicular Ad Hoc Network (VANET) has come up with lot of novel ideas such as vehicular communication, navigation and traffic controlling. In this study, the main focus is on congestion control at the intersections which result from unclear ahead. For this purpose, a city lane and intersection model has been proposed to manage vehicle mobility. It shows the act...

This study investigated the spatial distribution of copper (Cu), zinc (Zn), cadmium (Cd), lead (Pb), chromium (Cr), cobalt (Co), nickel (Ni) and arsenic (As) in roadside topsoil in the Qinghai-Tibet Plateau and evaluated the potential environmental risks of these roadside heavy metals due to traffic emissions. A total of 120 topsoil samples were collected along five road segments in the Qinghai...

Emission of heavy metals from traffic activities is an important pollution source to roadside farmland ecosystems. However, little previous research has been conducted to investigate heavy metal concentrations of roadside farmland soil in mountainous areas. Owing to more complex roadside environments and more intense driving conditions on mountainous highways, heavy metal accumulation and distr...

Vehicular Ad-hoc Networks (VANETs) have gained much more attention of the researchers these days because of its many important applications in transportation, to improve safety on roads, reduce traffic congestion, to enable efficient traffic management system etc. In VANETs data is disseminated from data center or RSU to the vehicles and simultaneously from vehicles to the data center or RSU to...

In the future vehicular networks with an increased number of transceiver antennas and higher vehicle speeds, more frequent beam switching is required to ensure quality communication, which poses challenges tracking speed resource efficiency. Integrated sensing communication (ISAC) provide a new solution cope this problem since radar echo can help predict vehicle’s location direction. Therefore,...

Vehicular Ad hoc Networks (VANETs) are emerging technologies with the primary purpose of establishing communications. Available protocols for data dissemination in VANETs faced issues like discontinuous connections, uncertainty about receiving messages, collisions, and latency. In this paper, a new method is presented advertising infotainment messages. The proposed has used store carry forward ...

Low-latency requirements of vehicular networks can be met by installing mobile edge hosts that implement computing in the roadside units (RSUs). Adversaries can, however, compromise these RSUs and use them to launch cyber attacks. In this paper, we consider an adversary selectively drops packets or corrupts between RSU passing vehicles. Such strategies would lead a higher number re-transmission...
