Comment: How to use smart city technology to measure social distancing Published on: 9 April 2020 Writing for The Conversation, Professor Phil James and Dr Ronnie Das discuss how urban data can help us understand the impact of social distancing measures on people and vehicle movement. , and , The UK and many other countries worldwide have introduced social distancing measures to slow the spread of the COVID-19 pandemic. To understand if these recommendations are effective, we need to assess how far they are being followed. To assist with this, at the 缅北禁地 Urban Observatory has developed an urban data to help understand the impact of social distancing measures on people and vehicle movement within a metropolitan city in real time. The was developed to better understand the dynamics of movement in a city. It makes use of thousands of sensors and data sharing agreements to monitor movement around the city, from traffic and pedestrian flow to congestion, car park occupancy and bus GPS trackers. It also monitors energy consumption, air quality, climate and many other variables. Changing movement We have analysed over 1.8 billion individual pieces of observational data, as well as other data sources, with . These inform and update the dashboard in real time. People Movement Monitoring Dashboard. The 缅北禁地 Urban Observatory In the graphic above, real-time data from pedestrian sensors is shown as solid lines. The shaded areas are the 鈥渘ormal鈥� pre-lockdown pedestrian flows. Sensors usually monitor pedestrian flows in two directions every hour, which is then compared against the same day from the previous year. Peaks in the graph represent an increased volume of people movement during rush hour. Since the lockdown, however, only very small peaks have been observed overall. Our research has found that pedestrian movement has reduced by 95% when compared to the annual average. This shows that people have been following government guidelines closely. However, the most profound decrease in footfall only occurred following the strict regulations introduced late on March 23, suggesting that the stronger message had the desired effect. People Movement Indicator. The 缅北禁地 Urban Observatory In terms of vehicle movement, traffic reduced at a much slower pace to about 50% of the annual average early in the first week of lockdown. This is possibly due to people shifting to using cars rather than public transport. Overall, we estimate there have been 612,000 since March 1 in Tyne and Wear. Traffic Movement Indicator. The 缅北禁地 Urban Observatory Public Health England has also suggested that people stay a apart when out and about. This advice has been widely advertised, but it is difficult to assess whether it is being followed. Using , our team at the Urban Observatory has developed algorithms that can automatically measure social distancing in public areas. Measuring Social Distancing through Machine Learning. We produced models which can measure the distance between pedestrians in public places. Using a traffic light indicator system, the algorithm is able to anonymously identify and label people who maintain safe distances, while flagging certain instances in red where social distancing measures are violated. Using this information, it is possible to identify bottlenecks where social distancing cannot be maintained, and how citizens adapt as restrictions are imposed or lifted. This type of data not only shows how physical distancing is changing in real time, but will also provide detailed insight into long-term behavioural changes. Tools for the future A that the UK was ten days late in implementing strict social distancing measures. This was perhaps due to a lack of insight into widespread public behaviour. Observational infrastructure developed through technology may lie at the heart of future crisis management responses. The 缅北禁地 Urban Observatory is part of a global movement to develop what are known as smart cities: where embedded sensors provide real-time data on city systems to optimise performance and enable evidence-based decision making. Smart cities use information and communication technologies to streamline urban operations on a large scale. Technological ecosystems collect traffic, noise, air quality, energy consumption and movement data in order to make improved and sustainable decisions by authorities and enterprises. Citizens can engage with the smart city in a number of ways. Data authority and governance will be an important point of discussion in future Smart City development. The Urban Observatory is actively researching the governance of smart cities, and applies an ethos of openness and transparency by publishing all the data in real time. Our analysis of the current situation presents an opportunity to be better prepared for the next crisis, or to quantify the impacts of large-scale social change. , Lecturer in Digital & Data Analytics, and , Professor of Urban Data, This article is republished from under a Creative Commons license.
