Using Smart City Tools to Evaluate the Effectiveness of a Low Emissions Zone in Spain: Madrid Central

Population concentration in cities brings new risks as an increase in pollution, which causes urban health problems. In order to address this problem, traffic reduction measures are being implemented, as pedestrianization areas and the definition of Low Emissions Zones (LEZ). When the effectiveness of these types of measures is in doubt, smart city tools provide data that can be used to scientifically asses their impact. This article analyzes the situation of Madrid Central (Spain), a LEZ subject to controversy. We apply statistical and regression analyses to evaluate the effectiveness of this measure to reduce air pollution and outdoor noise. According to the results, this LEZ was able to significantly reduce NO$_2$, PM$_{2.5}$, and PM$_{10}$ concentration locally, having the same positive impact in the rest of the city. In terms of noise, this measure is able to mitigate background noise levels generated by the road traffic.

Monitoring Sensors for Urban Air Quality: The Case of the Municipality of Lisbon

Sensors

Air pollution is a global issue that impacts environmental inequalities, and air quality sensors can have a decisive role in city policymaking for future cities. Science and society are already aware that during the most challenging times of COVID-19, the levels of air pollution in cities decreased, especially during lockdowns, when road traffic was reduced. Several pollution parameters can be used to analyse cities’ environmental challenges, and it is more pressing than ever to have city climate decisions supported by sensor data. We have applied a data science approach to understand the evolution of the levels of carbon monoxide, nitrogen dioxide, particulate matter 2.5, and particulate matter 10 between August 2021 and July 2022. The analysis of the air quality levels, captured for the first time via 80 monitoring stations distributed throughout the municipality of Lisbon, has allowed us to realize that nitrogen dioxide and particulate matter 10 exceed the levels that are recomme...

Promoting Pollution-Free Routes in Smart Cities Using Air Quality Sensor Networks

Sensors (Basel, Switzerland), 2018

Nowadays, citizens have a huge concern about the quality of life in their cities, especially regarding the level of pollution. Air quality level is of great importance, not only to plan our activities but also to take precautionary measures for our health. All levels of governments are concerned about it and have built their indexes to measure the air quality level in their countries, regions or cities. Taking into account the existing sensor infrastructure within smart cities, it makes possible to evaluate these indices and to know anywhere the level of pollution in real-time. In this scenario, the main objective of the current work is to foster citizens' awareness about pollution by offering pollution-free routes. To achieve this goal, a technology-agnostic methodology is presented, which allows for creating pollution-free routes across cities depending on the level of pollution in each zone. The current work includes an extensive study of existing air quality indices, and pro...

A Low-Cost Sensor System Installed in Buses to Monitor Air Quality in Cities

International Journal of Environmental Research and Public Health

Air pollution is an important source of morbidity and mortality. It is essential to understand to what levels of air pollution citizens are exposed, especially in urban areas. Low-cost sensors are an easy-to-use option to obtain real-time air quality (AQ) data, provided that they go through specific quality control procedures. This paper evaluates the reliability of the ExpoLIS system. This system is composed of sensor nodes installed in buses, and a Health Optimal Routing Service App to inform the commuters about their exposure, dose, and the transport’s emissions. A sensor node, including a particulate matter (PM) sensor (Alphasense OPC-N3), was evaluated in laboratory conditions and at an AQ monitoring station. In laboratory conditions (approximately constant temperature and humidity conditions), the PM sensor obtained excellent correlations (R2≈1) against the reference equipment. At the monitoring station, the OPC-N3 showed considerable data dispersion. After several corrections...

Filling the Feedback Gap of Place-Related ‘Externalities’ in Smart Cities: Empowering citizen-sensor-networks for participatory monitoring and planning for a responsible distribution of urban air quality

2015

With this paper, we present the set-up of the pilot experiment in project “Smart Emission”, constructing an experimental citizen-sensor-network in the city of Nijmegen. This project, as part of research program ‘Maps 4 Society,’ is one of the currently running Smart City projects in the Netherlands. A number of social, technical and governmental innovations are put together in this project: (1) innovative sensing method: new, low-cost sensors are being designed and built in the project and tested in practice, using small sensing-modules that measure air quality indicators, amongst others NO2, CO2, ozone, temperature and noise load. (2) big data: the measured data forms a refined data-flow from sensing points at places where people live and work: thus forming a ‘big picture’ to build a real-time, in-depth understanding of the local distribution of urban air quality (3) empowering citizens by making visible the ‘externality’ of urban air quality and feeding this into a bottom-up plann...

Towards a Smart City: Development and Application of an Improved Integrated Environmental Monitoring System

Sustainability, 2018

Environmental deprivation is an issue influencing the urban wellbeing of a city. However, there are limitations to spatiotemporally monitoring the environmental deprivation. Thus, recent studies have introduced the concept of “Smart City” with the use of advanced technology for real-time environmental monitoring. In this regard, this study presents an improved Integrated Environmental Monitoring System (IIEMS) with the consideration on nine environmental parameters: temperature, relative humidity, PM2.5, PM10, CO, SO2, volatile organic compounds (VOCs), UV index, and noise. This system was comprised of a mobile unit and a server-based platform with nine highly accurate micro-sensors in-coupling into the mobile unit for estimating these environmental exposures. A calibration test using existing monitoring station data was conducted in order to evaluate the systematic errors. Two applications with the use of the new system were also conducted under different scenarios: pre- and post-t...

Smart city environment and air quality dashboard irjmets

International Research Journal of Modernization in Engineering Technology and Science, 2020

The air pollution is increasing day by day due to various human activities. Air pollution is causing various harmful effects on environment and also human health. Air pollution has become the one of the serious issues in the today’s world. There are many reasons that regularly increases air pollution. Due to smoke, dust, poisonous gases released by transportation, industrialization and various other human activities into the air, causes air pollution. Air pollution is also damaging the ozone layer which causes severe environment hazards. Temperature is also increasing in today’s world. Increased temperature causes the chain reaction in environment. The increased temperature also has the severe side effects on environment and also human beings. Humidity causes some of the respiratory disorders and uncomfortableness. Water conservation is also necessary in today’s world. So, there is a necessity to monitor and control various environmental parameters. The Smart City provides smart solution to monitor and control environment and air pollution in a city. The IoT based smart city concept allows us to utilize the advanced communication technologies and provide improved services. IoT technology interfaced with cloud computing technology provides real time data to monitor and analyze. In this project we will be creating a dashboard where citizens will be able to access the temperature, humidity, air pollution, water level of water reservoir of their city. For this project we are placing three sensors i.e. DHT11 sensor, MQ2 sensor and ultrasonic sensor. The data collected from sensor will be transferred to the cloud. Through internet connectivity the citizens can directly access the original data which is captured by the sensor from the atmosphere from anywhere and at any time.
