Did city centres get a 'Super Saturday' bounce? | Centre for Cities - 1 views
-
There are three key things to note in this: Looking between late-February and mid-March, we see that the drop-off in footfall happened earlier and was much sharper in London than the other cities. Looking between early-April and mid-June, we see that the small and the medium-sized cities experienced less of a decline than London and the other large cities, and they also started to recover from this earlier. Looking between mid-June (when non-essential retail reopened) and Saturday 4 July, we see that while the trajectory is upwards everywhere, the small and the medium-sized cities have seen a much sharper climb back up towards normal.
-
There are three things potentially playing into this: City centres of large cities tend to have less residential and industrial space and are often concentrations of office jobs, which have been and still are being done from home. This limits how many workers are in the city centre compared to before. Larger cities, especially London are more reliant on public transport than their smaller counterparts. With public transport still limited in both capacity and use for public health reasons, it is now harder for people to travel into the centres of these cities. Due to their size, larger cities have more options for going to the pub or shopping beyond the centre and it may be that this has further reduced footfall in the city centre.
-
This and our other analysis on the topic suggests that we are unlikely to see large-scale changes in footfall and a ‘return to the normal’ in the city centres of the largest cities until office workers are welcome to and do return.

Using Location Data to Tackle Covid-19: A Primer | Institute for Global Change - 0 views
-
Aggregated Location Data Analysis of aggregated location data can be used to identify hotspots of transmission and forecast future trends on transmission. This can help governments measure the efficacy of existing measures as well as guide government decision-making going forward, on subjects such as public-health interventions and where to allocate testing and medical resources. This kind of data will be particularly significant for governments as lockdowns are eased; it is essential that governments are able to gather real-time insights on the effectiveness of their interventions.
-
Medical experts currently believe that the virus is transmissible within 2 metres – meaning a person must come in contact within 2 metres of an infected person to have a chance of contracting it from social interactions. Therefore, effective digital contract tracing requires highly precise data. However, most extant technology was not designed to rapidly geolocate devices at that level of precision, meaning most location data is less precise than 2 metres. The ongoing challenge for technologists is to either adapt extant technology for a purpose for which it was not designed or build new solutions that can deliver the required level of precision.
-
ost notably, if the data used for generating location and mobility insights is weak (low precision and low accuracy), then the privacy implications may be less stark – but the value of the exercise also decreases. Both individual tracking and generating aggregated mobility insights based on weak location data can result in flawed insights. This can have a range of undesirable costs for both individuals and governments.

Local public health officials and medics have complained that the government has not supplied sufficiently detailed information on local infections, the lack of which they say hampers attempts to quash new outbreaks.
-
Councils have been promised postcode-level data for weeks from Public Health England and the newly created Joint Biosecurity Centre. But some public health directors are concerned the centre has not been sharing data about potential clusters of infections with councils, which could enforce school or workplace closures that could suppress an outbreak at an early stage.

“If the only data you’re getting is ‘in this population of 90,000 people there are 40 positives’ it’s like looking for a needle in a haystack. If Leicester had got the data sooner they could have had a fighting chance of managing it,” said one public health director, who asked not to be named.
Aggregated mobility data could help fight COVID-19 | Science - 0 views
-
The estimates of aggregate flows of people are incredibly valuable. A map that examines the impact of social distancing messaging or policies on population mobility patterns, for example, will help county officials understand what kinds of messaging or policies are most effective. Comparing the public response to interventions, in terms of the rate of movement over an entire county from one day to the next, measured against a baseline from normal times, can provide insight into the degree to which recommendations on social distancing are being followed.
-
The research and public health response communities can and should use population mobility data collected by private companies, with appropriate legal, organizational, and computational safeguards in place.
Coronavirus (COVID-19) harmonisation guidance - 0 views
-
Harmonised principles set out how to collect and report statistics to ensure comparability across different data collections in the Government Statistical Service (GSS). Harmonisation produces more useful statistics that give users a greater level of understanding. When it comes to collecting data about the impact of the coronavirus (COVID-19) pandemic we are proposing a harmonised set of questions. Given the lack of testing these are to be considered experimental and not a full harmonised principle.
City-wide data in London: pandemic response & recovery (Part 1) - 0 views

The crisis more than ever demonstrated there is a very clear need for data in real time (or as near to real time) as possible to help inform decisions. It showed that problems-to-be-solved can’t be solved by the data one organisation holds alone: inevitably joining-up data from other sources is required. It also told us that without greater data collaboration our routes to creative, scalable solutions will remain limited.

The UK’s unusually fragmented approach to public sector data means often we talk more about how data is not shared or is not available than how it is more seamlessly used to understand common needs or meet shared objectives.

Mobile phone data for informing public health actions across the COVID-19 pandemic life... - 0 views
-
Decision-making and evaluation or such interventions during all stages of the pandemic life cycle require specific, reliable, and timely data not only about infections but also about human behavior, especially mobility and physical copresence. We argue that mobile phone data, when used properly and carefully, represents a critical arsenal of tools for supporting public health actions across early-, middle-, and late-stage phases of the COVID-19 pandemic.
-
Seminal work on human mobility has shown that aggregate and (pseudo-)anonymized mobile phone data can assist the modeling of the geographical spread of epidemics (7–11).
-
Although ad hoc mechanisms leveraging mobile phone data can be effectively (but not easily) developed at the local or national level, regional or even global collaborations seem to be much more difficult given the number of actors, the range of interests and priorities, the variety of legislations concerned, and the need to protect civil liberties. The global scale and spread of the COVID-19 pandemic highlight the need for a more harmonized or coordinated approach.

On the road again? Monitoring traffic following the easing of lockdown restrictions | U... - 0 views
-
Looking at the news across the UK, there are indications that the easing of lockdown restrictions has led to serious traffic problems. For instance, police were forced to close Falkirk Council’s Roughmute recycling centre two hours after opening it due to traffic building up on roads approaching the site. In Milton Keynes, IKEA was forced to close its car park just two hours after opening due to traffic volumes. Transport Scotland indicated a 60% increase in traffic on Saturday 30th May, compared to the previous Saturday, with traffic at the tourist and leisure hotspot of Loch Lomond up by 200%.
-
There are various ways to measure traffic volumes. Here, we look at Split Cycle Offset Optimisation Technique (SCOOT) data. The data is gathered from detectors installed at traffic lights. The purpose of the system is to coordinate traffic lights to improve the flow of vehicles. We accessed data on Glasgow’s traffic through an API provided by Glasgow City Council.
-
The aggregate pattern hides substantial variation at the different locations where the measurements are taken, which could explain why people may have seen large increases in traffic in their local area.

The Systems Thinker - Introduction to Systems Thinking - The Systems Thinker - 0 views
-
This volume explores these questions and introduces the principles and practice of a quietly growing field: systems thinking. With roots in disciplines as varied as biology, cybernetics, and ecology, systems thinking provides a way of looking at how the world works that differs markedly from the traditional reductionistic, analytic view. Why is a systemic perspective an important complement to analytic thinking? One reason is that understanding how systems work – and how we play a role in them – lets us function more effectively and proactively within them. The more we understand systemic behavior, the more we can anticipate that behavior and work with systems (rather than being controlled by them) to shape the quality of our lives.

The call for ‘raw data now‘ was not without purpose: but it was about the purpose of particular groups of actors: not least semantic web reseachers looking for a large corpus of data to test their methods on. This call configured open data towards the needs and preferences of a particular set of (technical) actors, based on the theory that they would then act as intermediaries, creating a range of products and platforms that would serve the purpose of other groups. That theory hasn’t delivered in practice

Wall Street Mines Apple and Google Mobility Data to Spot Revival - 0 views
-
LGIM’s asset allocation team takes Apple users’ requests for travel directions and adjusts them for weekly seasonality before projecting the data onto estimates for gross domestic product. So far, their analysis shows that the U.S. economy is holding up better than other regions and is gradually reopening, while there are signs of improvement in southern Europe as countries like Italy relax their movement restrictions.
-
In addition to LGIM, Societe Generale SA and Deutsche Bank AG are among those tracking mobility data. SocGen quant strategists led by Andrew Lapthorne said in a note on Monday that the data has helped them see that despite the easing of lockdowns in major economies, activity continues to be weak.

Boris Bikes are booming | FT Alphaville - 0 views
-
Last Sunday, April 19, with the capital’s roads bereft of traffic and the sun high in the sky, 39,889 trips were taken on London-based Santander Cycles — or, as most of us still tend to call them, 'Boris Bikes’. That was the busiest day of the year for bike rentals so far, according to Transport for London. And this past weekend was almost as busy: 37,995 on Saturday 25th, and 38,756 on Sunday.
-
While tube usage is down 93 per cent and bus usage is down 74 per cent, Boris biking (which requires more manual contact than either of those transport methods) appears to be soaring. Our anecdotal evidence (at least) suggests that insufficient knowledge about how the disease can spread across surfaces could be an important driver of the higher leisure usage we are seeing.
-
In New York, demand for the city's bike-share programme in the last week of March was down by 71 per cent compared with the same week the year before, according to a group of software developers and data explorers working with data feeds from NYC's Bike Share system. In Paris, where there are strict rules on when and where you can exercise, usage of public Velib bikes has fallen by 75 per cent year on year.

The problem of modelling: Public policy and the coronavirus - 0 views
-
The current epidemic is a classic application of what economists call “radical uncertainty” (most recently explored by John Kay and Mervyn King in their brilliant book of that title, which came out last month): in a world that has inevitably become too complex to be adequately captured in models, a world of both “known unknowns” and “unknown unknowns”, the most sensible response to the question “what should we do?” is “I don’t know”. At the onset of this crisis, we could not put probabilities on which forms of social distancing would best limit its spread because we’d never done it before. We didn’t know how people would alter their behaviour in response to the appeal to “save the NHS”. We didn’t even know whether reducing the spread was desirable: perhaps fewer deaths now would come at the cost of more next winter. And these were just the known unknowns. With a disruption as big as this, unknown unknowns are also lurking. We have no experience of the material and economic repercussions from shutdowns of this nature and their aftermath in a modern economy, and no meaningful way of assigning probabilities; nor of how people’s behaviour will evolve.
-
What the modellers should have said, right from the beginning, was that it was vital to establish two fundamental parameters: the incidence and the rate of contagion, both of which require mass testing, and without which mortality rates are impossible to decipher and hence sensible policy impossible to implement. It is frankly astounding that four months into this new virus such tests are only now being instigated.
-
. Shifting responsibilities down the system not only enables rapid scale-up, it has a further huge advantage: the power of decision is closer to the coalface of practitioner experience. We learn not just from accumulating and analysing codifiable knowledge – the domain of the expert. We learn by doing, or by trying to do things that we can’t do and that force us to experiment. A decentralized system learns from a litany of failed experiments running in parallel, and so it learns fast: teams copy other teams that have hit on something that works well enough to get the job done.
