Abstract
The concept of online monitoring of the urban environment is proposed. It is based on the online processing of hydrometeorological and traffic information received through the Internet of Things. The traditional approach of the Internet of things includes transfer and storage of huge arrays of measurements in digital form. This concept of online monitoring is primarily an analysis, evaluation of the results of processing information received from wireless networks. The concept was implemented at Nizhny Novgorod State University of Architecture and Civil Engineering in several services including Eco-routes, Quite-routes, in which the air pollution of the urban environment by vehicle emissions and the noise level from traffic flows are estimated in real time mode. The calculation is based on meteorological data and traffic flow velocity. The calculation and assessment of environment pollution is carried out at the request of the user via Internet. The concept includes micro weather and algal blooming monitoring of reservoirs and ponds. Developed services is the first to provide free short time health risk assessment for both decision makers and common internet users.
Highlights
Holistic approach of Internet of Things services was developed during last decade
Model of traffic flow intensity dependence on traffic speed and traffic composition during traffic congestion was used for online calculation of concentration of pollutants including nitrogen oxides of carbon oxide and hydrocarbons
To monitor the noise level created by traffic flows, it is proposed to use a semi-empirical formula for calculating noise levels Lae based on online traffic speed V and relatively stable traffic intensities N a calculated on the basis of special studies, the number of traffic lanes, and the share of heavy noisy vehicles Shv [4]
Summary
Holistic approach of Internet of Things services was developed during last decade. Local meteorological information of the nearest weather station is available free of charge in real time via the Internet all over the world. This information includes temperature, pressure, humidity, solar radiation, wind speed and direction. In some countries, including Russia, it is possible to obtain online information on the speed of traffic flows in cities. This information is based on processing messages about the coordinates of GPS beacons of municipal transport moving along city streets. The specific assessment procedures require additional information, which is described below
