The Challenge is to come up with a functioning application that leverages Open Data in an innovative and diverse way. The application should be related to one or more of these Smart City topics: Urban Mobility, Energy & emissions, Culture & tourism, Shopping & Retail and Collaborative city.
The City of Helsinki is a pioneer is opening its data repositories. Vast numbers of data sets are already available through the Helsinki Region Infoshare service (HRI). Now the city wants to encourage developers to come up with new kinds of applications, visualisations and dashboards using Open Data. For example shedding light on what is taking place in Helsinki or how things are evolving. Or mobile applications, that help tourists find interesting locations and events. Or allowing citizens to take part in the public decision making processes. The City of Helsinki encourages user-oriented and diverse use of the Open Data sets available in the HRI service, especially the open APIs. As a source of inspiration and assistance for developers the city is showcasing potential ideas, data sets and contact points related to the five Smart City topics. The additional information and links to other open data resources available on the Helsinki Smart City App Hack page.

HELSINKI CHALLENGES
These challenge descriptions will be updated with specific sources of inspiration and recent data sets during June. The five categories are Urban mobility, Energy & Emission, Culture & Tourism, Shopping & Retail and Collaborative City.
Urban mobility

Traffic and transportation is a major challenge of any urban environment where density, infrastructure, public transportation, weather and layout all play a major role. While each city has its own challenges, this theme focuses on how better access to information and services can lead to more efficient and effective mobility in the city.
Your brief:
Solutions for Urban Mobility should deal with, but are not limited to the following aspects:
- inform users on traffic condition.
- guide users in choosing the right means of transportation
- help promote the use of sustainable mobility.

Ideas for inspiration
“Create an app for winter bicyclists, that combines data about scheduled cleanups (Ylre) with realtime data about the snow ploughs (Stara) and weather. You can also include information about road works (Winkki) and public events (Linked Events) that may cause disturbance on the routes. Feedback about winter maintenance or other issues can be sent to the city from the app through the Open311 interface. Building registry data can be used to offer routes e.g. through residential areas rather than industrial zones.”
“Create an app that informs people when they need to move their car (to prevent it from being towed away). The user could be notified by the app whenever the city is planning to clean up the streets (puhdistussuunitelmat API) or when there are scheduled road works (Winkki API)”
Energy & Emission
As most of humanity moves to live in cities, energy efficiency and emissions control becomes a critical factor for our health as individuals, communities and as a planet. While many aspects of this issue are quite systemic and technology-driven, significant changes can take place from changes in our behaviour. How can we know more, spend less and live better are key questions and answers for advancement.
Your brief:
Solutions for Energy and Emissions should deal with, but are not limited to the following aspects:
- help cut wasteful energy consumption
- give tools to reduce energy spendings
- improve transparency and visualization of energy consumption
- provide Hints and tips on saving energy
- facilitate automation and control of energy consumption of electronic home devices

Create a live events application using the Linked Events API. The user could see the events on a map and, for example, filter them based on time, place, type of event and organizer. The event info could be enriched with weather forecast data and estimated travel time and public transport info.
Create a “One day in Helsinki” app. The app could focus on cruise guests and other tourists who visit Helsinki only for one day. What kind of needs could these tourists have? The app could use for example public transport info, events info (Linked events), restaurant and bar information and other useful information.

Shopping is a core activity of our daily lives and one that still offers the chance to stroll, browse and interact with fellow citizens making each experience unique. Apps can enhance that experience giving it a social dimension, facilitating discovery or easing comparison and transaction.
Think of shopping as a process and you quickly see the abundant opportunities for mobile app solutions: from “Pre-Shopping” (explore, discover) to “Shopping” (find, experience, purchase) to “Post-Shopping” (share, evaluate).
Luckily we have great mentors from the world of retail, payments and technology that will support you in this journey across Fashion, Food, Beauty, Restaurants, Leisure and so much more!

Collaborative City

When it comes to defining cities, citizenship participation is paramount. In a collaborative city, local communities come together to address some of their own challenges in a collaborative way. Whether it is caring for our young, old and ill or tendering to the socially excluded apps can provide solutions at scale. The collaborative city connects citizens with the decision making process in all questions of public affairs. It offers it residents tools to actively shape their communities.
Why should you care? With over 80% of the world population living in cities solutions for a more collaborative city not only will have a huge societal impact. It might well be the only way forward.
Your brief:
Solutions for the collaborative city should deal with, but are not limited to the following aspects:
- enable users to take part in the making-decision process.
- allow users to make informed decisions.
- help users to report their opinions around specific communal issues.
- empower users to create their own tools and solutions.
- improve efficiency and efficacy of the citizens’ participation process.
