Xi’an-Baoji Highway is one of the oldest and most important highways in northwest China. In this study, the concentrations (0-20 cm) of Pb, Zn, Cu and Cr at 5-1000 m distances in the roadside soils along Xi’an-Baoji Highway were experimentally determined to analyze their spatial distribution and evaluate their contamination levels. The spatial distribution (mg·kg) of Pb, Zn, Cu and Cr at 5-1000...

Traffic congestion is increasingly growing, especially in urban areas. One of the solutions for this problem is automated traffic. Many research programs have been carried out or are currently underway to implement automated road or highway systems, based on automatically controlled platoons of vehicles. The aim is to improve the flow and the safety of traffic by reducing accidents, while reduc...

Abstract Roadway sanding is a common practice in cold regions because sand increases the roadway friction when mixing with snow. However, after snow melt, sand imposes potential hazards to the traffic. Recovery of sand from highways has become an increasing concern not only for the reason of traffic safety, but also for being nonpoint pollution sources to nearby wetlands and streams. In this st...

This paper presents a preliminary study for the evaluation of transport-related air pollution situations in an urban area. The authors utilize a geographic information system (GIS) which integrates a vehicle emission model, pollutant dispersion model, backward trajectory model and related databases to estimate the emissions and spatial distribution of traffic pollutants in Taichung, Taiwan, ROC...

large urban areas are facing growing problems of noise pollutions. geospatial information systems (gis) can conveniently be adapted to gather, analyze and present noise information. gis can also be extended to answer to user specific problems through deterministic and statistics models. the objectives of this research were to measure urban traffic noise levels, analyze temporal and spatial dyna...

One of the most important pollution in world is air pollution. factors that cause this vehicles. Heavy metals have a great role component caused by vehicles and they negative effects on plant human health. In study, it was aimed to determine effect distance from highway leaf morphology anatomy economically Red Globe grape variety. Leaf samples were collected four different distances (road side,...

Nile Delta represents 63% of Egypt’s fertile agricultural land. Unfortunately, food chain contamination with potentially toxic elements (PTEs) was recorded along Cairo- Alexandria Highway within Delta. This paper aims to identify pollution sources PTEs (Cd, Pb, Co, Ni, Zn, Cu, Cr, and Mn), using multivariate statistics. Generally, the studied soil is alkaline loam about 3.69% CaCO3 1.97% organi...
