actually the risk meter just shows the numbers but fred shows much. more. credit for the smart way to get where you're going. with

the global auto and mobility show everybody on w. . every journey begins with the 1st step and every language but the 1st word published in the. eco is in germany to learn german why not play with him simple online on your mobile and free to suffer from d w z learning course nikos speak german meaning see. the city of the future is smot it's entirely interconnected to will regulate traffic save energy 5 crime assisted by big data and the internet all things brave new world or rather a surveillance nightmare what because it is look like and do we really want to live there autopsies a day on ship. more

than half of the world's population lives in cities and this number is steadily rising resulting in enormous challenges more people want traffic more pollution more energy consumption more water usage more waste smaller cities are supposed to help cope with these problems projects are popping up everywhere for instance in nigeria south korea india or malaysia a livable city that can think for itself how does this work like this for example. visions of the future this is a smart city as imagined by tech companies and urban planning is regular street lights are replaced by small poles which connect to other internet of things devices and provide broadband thanks to dr alice cause accidents hardly ever happen . and drones and robots deliver goods even coffee. in this future city solid grows underground at the urban farm.

fomented and virtual reality make processors more efficient. one example is that firefighters can be assisted by the control center and take helps to find and correct system errors to prevent damage before it happens. sounds fantastic but in order for these ideas to become reality technical preconditions are essential a central role for so the new mobo communications standard 5 g. it's the engine for the internet of things and enables interconnected infrastructures on a grand scale an expert on smart cities is you're not he is a researcher at the institute for technology management at the university of st gallen and has published a book with guidelines for cities that want to become smart we want to know how do i make a city smart and why. we want to improve people's lives. that's

how i would summarize the goal of a smart city. in order to do this it's important for citizens to be able to properly explain what kind of city they'd like to live in. that's the starting point and we can begin designing a smart city based on those demands. imagine you're the mayor of the city and want to turn it into a small. you'd have to consider the following. you need to make your city interconnected by adding census data for instance to cause the street to be able to regulate traffic or to measuring station station throughout the town. the smart city is usually a combination of the different urban systems that we have. for the most part that means mobility systems housing system. systems energy systems

education systems and so on anything affecting citizens in their everyday lives can be assigned a digital shadow. that simply collecting data is insufficient data is no end in itself data needs to be prepared and. based on this. one someone is. driving restrictions. anything is possible. to build a small city one must do 3 things connected via data and data to find solution for the citizens but how do i benefit from the smart city here. in. the city saves taxes by using resources more. patiently with the help of sensors

public spaces are only irrigated when they're too dry. the garbage bins are only emptied once they're full. in helsinki garbage trucks have become obsolete waste is transferred to underground collection points without noise or pollution. in rio de janeiro a smartphone app is enabling residents to shape their surroundings the app smart favela create a 3 dimensional avatar of the shantytowns when city planners come up with new ideas these can be looked at on the app and then citizens can vote on them. in palo alto in the u.s. parking lots now have sensors these notify citizens whenever a parking space is free the city's traffic is constantly recorded. smart robo cops are supposed to make do by safer the police robots are equipped with cameras and can find persons through facial recognition tech reports can be filed on

a touchpad. and dry hole that ukraine citizens can view the incomes of civil servants and check on how politicians have voted in the city council. the city owned businesses laid bare their accounts using open data in the fight against corruption. in darmstadt germany interconnected sensors assess the air quality and send this information to a data center which analyzes air pollution and if necessary reports bad air quality . in order for these systems to work vast amounts of data on all citizens are required but who ensures that the data is safe and who has access to it different solutions exist. is essential for a small city it provides the basis for designing intelligent applications for the city. but what about data protection. to be clear in

a smart city there is no protection from data being collected but on the other hand it's precisely this data that provides the basis for implementing and controlling this city system. as a result very careful and conscientious decisions need to be made regarding how the data is handled. if the city controls. when it comes to data protection but most cities lack the technical expertise to process and analyze the data for this reason many cities cooperate with big tech companies they have the capacity and the algorithms needed to work with data. like. the alphabet corp it will construct an entire district of tarantulas with the newest technology. but the data stays with corporations like alphabet which is problematic as they use our data to make money. an entire city state and that's really offers

many opportunities so what to do experts argue for so-called data utilities these are publicly financed but independent organizations they managed to control access to data anyone interested in developing smart city solutions could use them no matter if city owned business. or big company a promising approach i think everyone should be able to profit from. their utilities personal data is anonymised as a citizen i cannot influence which state of mine is being used. to cold a project by the european union goes even further to empower individuals to control their data citizens themselves should decide whether personal information stays private or if it's being shared in order to make the city smarter. pilot projects have been running in amsterdam and barcelona since 28. should be understood as

a public infrastructure as a common good water like electricity like transportation like the air we breathe. they also believe that citizens can responsibly deal with their own data. a desirable goal. should be in charge of their own data private corporations or governments control data in the smart city where do you draw the line when it comes to surveillance an example from. taxi headquarters in shenzhen china the red cars occupied the green car. algorithms used right histories to predict which areas are likely to have a lot of customers and when. drivers can then directly head to these locations like. his car is part of the network consisting of around 20000 taxis. and it's equipped with an interior camera meaning that headquarters can watch him

work and listen in on all conversations. in the beginning i was uncomfortable as i didn't really know much about it and felt constantly observed but actually there is no reason for concern the cameras protect the customers and us drivers to . privacy is ensured as not everyone can view the videos. according to the taxi headquarters all data is well protected and deleted after $72.00. they say the system is great for educating drivers and the footage can be used to settle conflicts complaints the taxi provider also says customers complain less frequently and that most likely cameras as do drivers who are now less worried about being threatened but the police also has access to the videos how freely people really converse and the taxis. another problem. parking lots answers. garbage bins are connected to the internet and offer potential

gateways for hackers theoretically one weak link is all it takes to shut down the city's central servers and cyber terrorists could go even further is tonia demonstrates how to protect oneself. in terms of digital administration and stonie and the 3rd way and yet estonians can vote online and almost all public services are digitally accessible but this also increases vulnerability. in 2007 is tenuous targeted by cyber attacks from a global network of connected thoughts. both online banking and government websites where fact it. estonia has implemented annual international training on fighting attacks from hackett's they organized by nato cyber defense and over 20 nations the military and tech companies take time to. question is look we got this. cyber attack the question is when you get to the subject of

security is not something you can do once because that landscape are changing every day cyber security is also crucial for smart cities they are becoming a steadily increasing economic factor tech companies use smart cities around the world to test their future technologies the big question is does this benefit the citizens to a point of importance to me who controls the applications and who owns the data we need to find responsible solutions and the citizens interest what's your opinion would you like to live this way i was not is your city join the discussion i'm looking forward to your feedback bye for now and see you next time.

did you know that 77 percent of black because you are younger than the pot. and you know what the 77 percent we talk about the issues. in this edition of south african historian come along i'm accusing she can post a comic style history book to help children understand and identify with her african roots the 77 percent next on d w. e the way you use them for all. and mine are some celebs. who can be honest their images. and why do we find the sound. of 6 legged traffic analysis
