Disinfection robots, thermometer robots, smart tunnels, automatic passenger counting, powerful ultraviolet lamps and other examples of how new technologies reshaped public transport amid the COVID-19 outbreak.
The coronavirus pandemic has led to significant changes in many areas of life in just a few months. As the coronavirus continued to spread around the world, governments in several countries took measures to restrict movement, and people themselves tried to avoid traveling on public transport. The demand for the services of transport operators has dropped drastically. So, according to the Moovit Public Transit Index, passenger traffic in public transport on April 15, 2020 decreased in Israel by 92.1%, in Rome – by 89.2%, in Madrid – by 88.1%, in New York-by 74.8% and has not yet recovered. City residents are afraid to use public transport actively again, and their fears are fully justified. High daily passenger traffic and high frequency of contact between passengers make public transport an ideal environment for the spread of infections. The problem of fighting the spread of infections while maintaining normal life activity is particularly acute for large cities, such as Moscow or Beijing, where daily passenger traffic reaches 19.4 and 12.3 million passengers respectively. The average density of passengers on a bus or in a traincar at the same time ranges from 2 to 5 people per square meter, while, according to World Health Organization (WHO) recommendations, in order to comply with safety standards, passengers must maintain a social distance of 1.5 meters. Furthermore, virus particles can remain for a long time on public surfaces inside a bus or a traincar. Handrails on public transport are usually made of plastic, on which the coronavirus can remain up to 3 days, according to the New England Journal of Medicine. By touching them passengers increase the risk of contagion.
The key task for transport operators is to make the usage of public transport safe. To help them solve this problem came technology -all kinds of robots are widely used among innovations. With their help, it is possible to carry out disinfection effectively and safely without the involvement of staff. The Hong Kong Metro, also known as the Mass Transit Railway (MTR), together with the biotechnology company Avalon Biomedical Management Limited, has developed a disinfection robot that can disinfect even the most inaccessible places of traincars and stations. In addition to disinfection, robots can cope with more complex tasks. So, in Ningbo Lishe International Airport was tested a 5G-supporting robot-thermometer, which can measure temperature at a distance of 5 meters up to 10 people simultaneously and also identify those who are not wearing a face mask. Another innovation in many transport operators is the sanitary gate. According to Giulio Barbieri, one of the manufacturers, this is a “a tested, safe, and effective method to sanitize people and objects in just 5 seconds, killing up to 99% of any pathogenic microbes on the surfaces, including COVID-19”For example, the technology was tested in the Moscow and Dubai metros. In Moscow the clothes of the employees entering the depot were processed using a disinfection tunnel; at the same time, the territory was manually disinfected, so that the entire depot was safer for the staff.
The process of digitalization of ticket systems, which began long before the pandemic, also had a positive effect. Thanks to the competent actions of transport operators, the number of contactless payments in public transport around the world increased by 187% in the period from April to June, as evidenced by a report from Visa. Following WHO recommendations, many transport operators have made it mandatory to wear masks and maintain social distance on public transport. A number of digital technologies have been developed to comply with these rules. In the Beijing metro, compliance with a mask regime is controlled by cameras with a facial recognition system that can identify people. In addition, in the Panama Metro, observance of social distance is monitored by sensors which determine the degree of capacity of train cars. The technology called Mastria, which aggregates information from train weight sensors, ticket machines, signalling, management systems, CCTV and mobile networks for the Panama metro was developed by Alstom (a french manufacturer specializing in the production of infrastructure for rail transport) and installed almost a year ago. In just three months, thanks to artificial neural networks, it was possible to reduce average waiting times at stations by 12%. This development became particularly relevant during the pandemic. The Moscow metro is planning to introduce a similar technology. To maintain the social distance digital displays with colored indicators that reflect the level of capacity of subway cars will be installed. In the Moscow metro a new generation of traincars with an automatic air disinfection system built into climate control systems helped to reduce the risk of infection. It makes it possible to disinfect the air without disrupting the train schedule and attracting employees. The Moscow metro rolling stock consists of more than 50% of train cars with built-in UV lamps, and this percentage is constantly growing. After evaluating the effectiveness of using UV lamps to disinfect public transport, the transport operator MTA New York City Transit, together with Columbia University, launched a pilot project worth 1 million dollars on the use of disinfecting lamps. During the first phase of the project, 150 autonomous lamps were purchased and installed to decontaminate wagons, stations and buses in New York, during the second phase it is planned to install equipment in commuter rails. To carry out disinfection measures, the New York City Subway took unprecedented measures – the closure of the subway from 1 to 5 a.m. daily.
The use of robots, disinfection tunnels, digital technologies, ultraviolet lamps, and intensive work of staff – all this helped to reduce the risk of the spread of coronavirus in public transport and made a significant contribution to fighting the global problem. According to the coronavirus distribution model, developed by Imperial College London at the beginning of the pandemic, if no action had been taken by mid-March there would have been over 500,000 deaths from COVID in the UK and over 2.2 million in the USA. At the moment, in the middle of October, there are about 43,000 deaths in the UK and about 214,000 in the USA. Of course, these are high rates, but they could have been much higher if the necessary measures were not taken in time. Technological innovations already available today will continue to be used, which will make the stay of passengers on public transport more comfortable and safer, reducing the risk of the spread of any infectious disease, especially during the flu and cold seasons.
