AbstractIn India, transportation sector is growing fast and the number of vehicles on Indian roads is increasing at a rate more than 7 percent a year. During the period of 50 years from 1951 to 2001, the number of vehicles has increased from 0.3 million to 43 million i.e. an increase of almost 143 times. This has led to overcrowded roads and noise pollution. The transportation sector is one of the major contributors to noise in urban areas, accounting to as much as 55 percent of total noise on t...

In cold, high-latitude regions, snow evaporation can significantly influence the snow water equivalent and thus change the regional water balance in early spring. In order to explore how the snowfall event and environmental factors affected the snow evaporation rate in the northern Daxing'an Mountains in China. From the snow melting period of March 2016 to April 2018, the eddy covariance method was used to explore the relationship between environmental factors and snow evaporation. The resul...

Every year 93 billion tonnes of raw materials are consumed, but only 9% of them are reused: a potential of about 3 trillion dollars worldwide, 88 billion in Italy, according to Growth Within: A Circular Economy Vision for a Competitive Europe by Ellen MacArthur Foundation with McKinsey. A vehicle is potentially recoverable, in its components for more than 95%, an industrialised process of treatment of end-life vehicles (ELVs). Optimising raw material recovery is currently possible and advantag...

Healthcare wastes are produced from all medical and therapeutic activities in hospitals and healthcare centres. Around 15-20% of these wastes are classified as infectious wastes that could be hazardous. Therefore, an effective approach is required for handling costs and environmental issues. In this paper, a bi-objective Mixed-Integer Linear Programming (MILP) model is presented for logistics of infectious and non-infectious wastes. The proposed bi-objective model aims to minimize network costs ...

This research applied passive air pollution samplers to monitor the concentration of the pollutants nitrogen dioxide (NO2) and ozone (O3) in order to investigate the relationships between pollutant concentrations and meteorological variables. The study was carried out in three strategic sites in the municipality of Erechim, Brazil, which provide intense traffic of small and large vehicles. The pollutant analyses were performed using the method of UV/VIS spectrophotometry. NO2 concentrations vari...

Optimal evacuation routes are crucial to protect workers’ safety when accidental leakage of toxic gas occurs in chemical plants. However, the majority of route optimization focuses on the transport field and few on the evacuation routing optimization in chemical plants. This paper proposes a dynamic evacuation routing optimization method for chemical plants under toxic gas release scenarios. From the complete accident scenario set (CASS) built with wind fields and leakage sources, the leak...

Transport networks, including highways, have many negative ecological impacts, such as habitat loss and landscape fragmentation. One of the most consicuous negative effects is wildlife vehicle collision (WVC). The basic aims of this study, conducted on the KÄąrÄąkkale-ÇankÄąrÄą Highway, Turkey, are the following: i) identifying locations of WVC events, ii) modeling the effects of landscape pattern and traffic characteristics on WVC and iii) proposing a solution to mitigate WVC. In the st...
