Wearables, big data and traffic regulation

Big data could help citizens in numerous ways and it’s up to our phantasy to invent new uses. In this short post I will work on the subject of wearables, big data and traffic regulation, something very useful globally as urbanization advances rapidly at a global scale. Wearables with GPS geo-localization that will count the number of citizens waiting in a metro station platform could be meaningful to reduce human stress and delays. Such delays are the reason for many missing meetings as employees (and even employers) arrive often late at work due to such disturbances. Big data could give traffic controllers the opportunity to augment the frequency of metros’ in a particular metro rail line until demand from passengers to enter wagons drops. But it is not only trains and subways where such an idea could be used.

It could be used to count passengers in a particular airport or a particular airport desk, to count drivers willing to take a turn towards a big highway and so on (especially when connected with route plans that people have picked in their digital traffic advisor). That will resolve many of today’s problems citizens daily have in large urban areas all over the world, from Shanghai to New York.

A particular scan of data could even calculate the number of social media messages about high traffic in a particular area and thus to help who organizes the traffic to send more buses, taxis or trains to relieve a problem. In such a case an alert level could be set, when for example messages about traffic are more than 50 in a small neighborhood.

In a less developed country where people don’t have enough money to buy these new gadgets, SMS could be traced in order to inform if particular products are available in a small local market of a poor African country. Linnet Taylor and Ralph Schroeder open up very interesting questions about big data in one of their recent articles. They inform about the MIT’s “Billion Prices Project (Cavallo 2013 in Taylor and Schroeder 2015, p.504) which is a similar idea but at a much larger scale.

Will citizens be more willing to provide such data if they can immediately use the outputs of such a survey? I think yes. Where positive results of an action are immediate and more tangible, people will feed such initiatives with more data for their own good.

Many companies that provide GPS orientation programs provide updated information about traffic in big cities. What if all these could be transformed in an all – included program which will combine road, train and air traffic and that will really inform about traffic jams in order to avoid delays. Buying tickets and the opportunity to see tickets availability would make such a program far more desirable.

A big fear of today’s citizen in a big metropolitan area is sudden traffic chaos. I think that people are ready to accept less privacy when outcomes really help them immediately towards a better life quality.  Αfter all improving our lives is  a form of social change.

A critical question is where data scan and elaboration will be done (Taylor & Schroeder, 2015, p.504). Let’s suppose that a heavy traffic jam hits Mombasa. Are local authorities ready to use such technologies or this will add new costs to the local economy, as technologies and scientists will have to be imported? The two scientists also inform about the dangers of a “top-down approach” ((Taylor & Schroeder, 2015, p.504), where questions (of data surveys) and needs are simply guided by officials both in national and international organizations and are not necessarily what people ask about.

Talking about the digital ethics and the digital concerns over big data was something very trendy during the last ten years. Can we talk about politicization of data in such a field, in a way similar to the one Taylor & Schroeder discuss about over other development issues (Taylor & Schroeder, 2015, p.506)?  My answer is yes, as decisions that will follow the use of these data (the decisions of traffic controllers for example will affect the lives of thousands of people). After all it is a political judgement what you consider high traffic in your polis (city) and the decision you make to inform others on social media. Speculation over the use of traffic control data could affect the elections in a large metropolitan area, if a candidate will blame the current mayor that she/he is not doing enough to press for more metro’s wagons in a particular line. But it will also affect private companies’ profits, positively or negatively.

Reviewing Taylor’s and Schroeder’s article, I can notice that one of the most important questions they pose is “what ‘development’ means to data scientists” (Taylor & Schroeder, 2015, p.508). How were they educated on development (both in class and from the environment they have lived) and how that will influence their choices?

They also pay attention to the fact that not all scientists gain allowance to use big data. They need prior reputation and good connections in order to gain such a permission. Thus only a small circle of scientists could end up on using big data (since big data is not always open data) and the rest will be constrained to do what is a small scale data research or a qualitative research(Taylor & Schroeder, 2015, p.510). The two scientists stay on “power and knowledge asymmetries” (Taylor & Schroeder, 2015, p.516) and insist on education of people about their rights (Taylor & Schroeder, 2015, p.516). When entering what I would call this new marvelous world, the world of big data, you have to take account of such complexities.

    I think development definitely is heading towards a situation where traffic is increasingly monitored in one way or another. Waze and similar apps already offer the opportunity for users to report for example traffic accidents. Big data and automatic information upload is obviously taking it one step further. I don’t think there will be traffic controllers changing traffic flows though, the data coming in will be too vast for humans to control. Artificial intelligence is the future and will not only analyze the incoming data, but also suggesting solutions to alleviate the potential traffic jams.

    That people will allow for more surveillance (in a way) as long as they feel they receive something tangible or a perceived better quality of life in return, is a very interesting idea. Personally, I am not sure I would fall into that category, especially if the ones doing the surveillance are humans just like you and me. If it were it a neutral AI, then I would be more accepting. But then again, how could we be sure the AI is really neutral. And what kind of society are we living in when an AI is so powerful?

    Having an app with combined traffic information and ticket purchase ability is a great idea and really something that should be developed in megacities. Maybe you should work with app developers to make it come true?!
