It is important to forecast the pedestrian flows for organizing crowd activities and making risk assessments. In this article, the daily pedestrian flows in the Tiananmen Square are forecasted based on historical data, the distribution of holidays and weather conditions including rain, wind, temperature, relative humidity, and AQI (Air Quality Index). Three different methods have been discussed...

In this study, Air Quality Index (AQI) in Besiktas was intended to be predicted by Artificial Neural Networks (ANN) and k Nearest Neighbors (kNN) algorithms. For purpose, eight parameters have been selected which may affect the AQI. These are PM10, SO2, CO, O3, temperature, humidity, pressure wind speed, respectively. 124 data for 2015, 2016, 2017 2018 January, includes parameters, were determi...

Starting from China's low-carbon economic situation, analyze the relationship between industry’s contribution to GDP and AQI, make a conclusion that carbon emissions will increase linearly with current growth if no interference. The second part describes status quo of economy in three-sector. Investigate situation trend each industry general, then corresponding GDP, AQI interactive ten typical ...

Crop residue burning produces a lot of polluting gases and fine particles, endangering human health, damaging soil structure, causing fire accidents. In addition to the impact on local environment, pollutants can spread with wind more distant areas their air quality. Nevertheless, comparative analysis two common parameters, number points, burned area urban quality indicators has not been report...

In recent years, air pollution has become a serious threat, causing adverse health effects and millions of premature deaths in China. This study examines the spatial-temporal characteristics ambient quality five provinces (Shaanxi (SN), Xinjiang (XJ), Gansu (GS), Ningxia (NX), Qinghai (QH)) northwest China (NWC) from January 2015 to December 2018. For this purpose, surface-level aerosol polluta...

Rapid industrialization and urbanization are rapidly deteriorating ambient air quality, especially in the developing nations. Air pollutants impose a high risk on human health degrade environment as well. Earlier studies have used machine learning (ML) statistical modeling to classify forecast pollution. However, these methods suffer from complexity of pollution dataset resulting lack efficient...

Air is one of the most fundamental constituents for sustenance life on earth. The meteorological, traffic factors, consumption non-renewable energy sources, and industrial parameters are steadily increasing air pollution. These factors affect welfare prosperity earth; therefore, nature quality in our environment needs to be monitored continuously. Quality Index (AQI), which indicates quality, i...

concerns have been raised about the adverse impact of dusty air pollution (dap) on human health. the aim of this study was to find the association between dusty air pollution based on air quality index (aqi) and the risk of allergic diseases in southwestern provinces of iran, with assessing cytokine profiles and lymphocyte immunophenotypes.in this case control study 148 individuals participated...
