This is the second blog post out of the 5 blog posts that will provide a view of the 5 AEGIS high level scenarios.

Scenario 2: Data-enabled services for enriched real-time navigation system

Remember Alex, the researcher whose team created advanced data-services in the automotive industry in our previous scenario?

We will now see how a software company managed to create an enhanced navigation system, leveraging this work!

The background Elias is a senior developer in Auto4Techs, a software company based in Austria, and his team has developed a land-based navigation system, which entered the market two years ago and has managed to gain a market share about 10% so far.
The driving need The team is now in the process of brainstorming for ways to become more competitive; however, there are many established systems in the market and they cannot find a promising way to differentiate their core offering. Elias states that it would be interesting to extend the navigation system with additional layers of information, providing services on top of the core product. He suggests enriching the system with accident risk annotations and real-time alerts for events that could affect traffic. However, although all team members find the ideas interesting, nobody is aware of a way to acquire the information required for the first one. At the same time, the second one would require increased effort in terms of identifying possible input sources, retrieving and processing data and nobody in the team has experience on natural language processing to do that. They bring their ideas to the management level to ask for time and resources to work on these new services, but they are informed that the company has decided to reduce the effort devoted to the navigation system and the team must come up with solutions that do not require significant in-house development effort.
The first steps Elias proposes that all team members search for existing solutions that could be leveraged towards implementing the new services more easily and quickly, both internally in the company and externally and report back their findings. Through this process, one of his colleagues comes across AEGIS and sends the link to Elias.

Elias opens the interactive map that shows the AEGIS services by region and navigates to Austria. He discovers that AEGIS offers several data-as-a-service services with information about Austria. More specifically, he finds six that are extremely interesting:

  1. Weather service providing precipitation, clouds, pressure, temperature and wind measurements, which can be configured based on the desired granularity in terms of location and time intervals
  2. Crime service providing geo-located crime events based on open data
  3. Car accident service providing geo-located car accidents with severity annotation based on open data
  4. Events service providing a configurable real-time stream of a wide-variety of events, including riots, concerts, football matches etc.
  5. Road damage indicator service, which provides geo-located indicators of possible road damage. The service is provided by a research centre for environmentally friendly cars based in Austria and is only available for the city of Vienna (more details on how this was created here).
  6. Car accident service, similar to the third one, but provided by an international auto insurance company which also operates in Austria, based on their internal data

The first four services are tagged as AEGIS offerings, whereas the other two are proprietary services provided by other organisations. Elias reviews the services and examines their expected output, the number of entities already using them, their maintenance information, terms of use and price and believes they will significantly facilitate the development of the enriched navigation system. He brings them to the manager who decides to use the four services provided by AEGIS and the one from the research centre regarding road damage since it is highly important information that they could not acquire elsewhere. He proposes, however, to skip the last one from the insurance company as the alternative offered by AEGIS is less expensive, since it is based on open data

Adoption Phase Elias and his team proceed to gain access to the five services which they can then easily consume through the provided RESTful APIs. Since all services provide latitude and longitude for each entry, the team can very easily integrate them into their navigation system. The only addition required is to design intuitive signs to represent each of the newly acquired pieces of information, e.g. road damage sign, large number of accidents in the area, large concert starting within the hour, etc. Furthermore, aside from the original two ideas (accident risk estimations and event notifications), Elias and his team are able to leverage the acquired services towards developing an additional service for their navigation system, which they call “ParkSafe”, which provides indications on the map to avoid specific regions for parking due to extreme weather conditions, high crime rates or local events like protestations, strikes etc.
Product release In the end, the team releases the updated navigation system with various subscription modes, to let every driver decide which services to include in her system. Their navigation system is now the most inclusive navigator for the city of Vienna and the responses from the local drivers are extremely positive, so the manager has already asked them to examine the availability of AEGIS services for other locations as well.

Naturally, we have identified several challenges to address in order to enable the described scenario, including the following:

  • The desired level of localisation for the provided services may not always be possible to achieve
  • Public data sources can change suddenly in both structure and content without any notice
