How it all started, answers to questions that weren’t asked.

About 3 years ago a group of fire fighters at a fire station in Amsterdam was confronted with a new navigation assistant in the fire truck. From a conceptual point of view the idea of having navigation assistance in a fire truck might be nice, but there are practical implications when using a system designed for normal traffic in an emergency vehicle , remember fire trucks are allowed to defy all the rules in traffic! Without elaborating on why it is not working as it should, the more abstract point is that it gives answers to questions we never asked.

The answer you get from a navigation assistant is based on the question ‘What is my next step in getting to my destination?’ where fire fighters are more interested in ‘What is my final destination?’. Sitting down and discussing the subject the conclusion was that they were interested in an overview on a map with both the location of the fire station as well as the location of the incident marked.

The route itself is not that interesting as the knowledge of the fire fighters about the local area is at such a high level that they easily beat a navigation assistant.

To solve this problem, we were confronted with a few technical requirements:

  1. Real time, the system has to respond to an alarm at the fire station in a few seconds.
  2. It should not require any manual interaction.
  3. Low maintenance at station side.
  4. We should have access to the raw data

Items 1, 2 and 3 were pretty easy to solve, item 4 however turned out  to be a more challenging one.
Although the full message was sent ‘over the air’ via a paging protocol, it wasn’t really a structured data format. It was just a compression of various seemingly random chosen fields into a maximum width of 140 characters.
After some trial and error we were able to extract the various fields with about a 98% accuracy. Now that we had the data and the various pieces of information we needed to distribute this data. In our team we had some discussions about what format to use.

During that time we got introduced to RDF, where the flexibility of the data model was what was intriguing us most. This would perfectly fit with requirement 3. We could still enrich the data dynamically without breaking already installed systems at the fire stations.

How does it work now

After tying all loose ends together the structure of the solution is very elegant and simple.

  1. We scan the via air broad casted message for station ID’s we are interested in. Whenever a station ID we want is detected we generate RDF data.
  2. The vocabularies used are partly standard, partly domain specific.
    The standard ones include:

    • Meta data, all the information about the publishing of the data,who/when/where/what: OWMS / DCMI
    • Events, the alarm is an event, and we record everything relative to the event: SEM
    • Location, the crew is dispatched to a location: GEO
    • Address, the incident takes place at a certain address: vCard

    The domain specific vocabulary is a subclass of event, describing:

    • Units dispatched to the incident
    • Fire station involved
    • Deployment plans used.
  3. This information is stored as RDF data on a public URI. This URI is then dispatched to the relevant fire stations.
  4. The software at the stations uses Semantic Web techniques to retrieve the data from the URI, and show the relevant information on the map.

Advantages

Due to the flexible structure of the data model we have been able to enhance and update the data model without touching the client software. If the clients needed additional functionality it needed a software update of course, but the software update was not necessary to accommodate a data model update.

From a Semantic Web point of view we now start very early in the incident describing the data, we actually do know what we are talking about. Because we gain knowledge about the actual incident at a very early stage we are able to assist and connect multiple sources of information in a later stage.

From a non technical point of view we have some results we didn’t expect. Because the truck driver now has a better idea of where he needs to go, he is more relaxed and better concentrated behind the wheel, resulting in more secure and save driving.
As there is a map at the station, the fire fighters look at the map more often, and get a better idea of their work area.

Outside in development

Due to the close connection with the people actually using the system, we were able to implement modifications and wishes really fast. We didn’t go through highly detailed project plans and endless meetings, but decided to start where we thought it was easiest and just took it from there, never loosing sight of the technical strategical direction we wanted to go and the targets to achieve.

Future plans

Our current focus now is to extend the screens with information from the deployment plans. More on that in the near future….

  1. Very good blog you have here but I was curious if you knew of any community
    forums that cover the same topics talked about here? I’d really love to be a part
    of online community where I can get feedback from other experienced people
    that share the same interest. If you have any recommendations, please let me know.
    Cheers!

  2. Thanks for another wonderful article. The place
    else may just anyone get that kind of information in such a perfect
    method of writing? I’ve a presentation subsequent week, and I’m at the look
    for such information.

  3. I am really impressed with your writing skills and also with the layout on your blog.
    Is this a paid theme or did you customize it yourself?
    Anyway keep up the nice quality writing, it’s rare to
    see a nice blog like this one nowadays.

  4. Have you ever thought about adding a little bit more than just your articles?
    I mean, what you say is valuable and all. But think about if you added some great graphics or video clips to
    give your posts more, “pop”! Your content is excellent but with images
    and clips, this blog could definitely be one of the best in its niche.
    Awesome blog!

  5. After I originally left a comment I seem to have clicked the -Notify me when new comments are
    added- checkbox and from now on each time a comment is added I recieve four emails with the
    exact same comment. Perhaps there is a means you are
    able to remove me from that service? Appreciate it!

  6. This design is steller! You most certainly know how to keep a reader amused.
    Between your wit and your videos, I was almost moved to start my own blog (well, almost…HaHa!)
    Excellent job. I really enjoyed what you had to say, and more than that, how
    you presented it. Too cool!

  7. When I originally commented I clicked the “Notify me when new comments are added” checkbox and now each time a comment is added I get four emails with the same
    comment. Is there any way you can remove people from
    that service? Appreciate it!

  8. I would like to thank you for the efforts you’ve put in penning this site.
    I am hoping to check out the same high-grade blog posts
    from you later on as well. In fact, your creative writing abilities has
    motivated me to get my own, personal site now 😉

  9. Do you mind if I quote a couple of your posts
    as long as I provide credit and sources back to your website?
    My blog site is in the very same area of interest as yours and my visitors would definitely benefit from some of
    the information you provide here. Please
    let me know if this ok with you. Cheers!

  10. Hello, i believe that i saw you visited my web site thus i came to return the desire?.I am attempting to
    find things to enhance my web site!I assume its adequate to make use of some of your ideas!!

  11. I was wondering if you ever considered changing
    the page layout of your website? Its very well written; I
    love what youve got to say. But maybe you could a little more in the way of content so people could connect with it better.

    Youve got an awful lot of text for only having 1 or 2 pictures.

    Maybe you could space it out better?

  12. Howdy, i read your blog from time to time and i own a similar one and i was just curious
    if you get a lot of spam responses? If so how do you protect against it, any plugin or anything
    you can advise? I get so much lately it’s driving
    me insane so any support is very much appreciated.

  13. I’ve been browsing online more than 3 hours today, yet I never found any interesting article like yours.
    It is pretty worth enough for me. In my opinion, if all site owners and bloggers
    made good content as you did, the internet will be much more useful than ever
    before.

  14. Hmm it seems like your site ate my first comment (it was super long) so I guess I’ll just sum it up what I had written and say,
    I’m thoroughly enjoying your blog. I as well am an aspiring blog writer but I’m still new to the whole
    thing. Do you have any tips and hints for newbie blog writers?
    I’d certainly appreciate it.

  15. Heya this is somewhat of off topic but I
    was wanting to know if blogs use WYSIWYG editors or if you have to manually
    code with HTML. I’m starting a blog soon but have no
    coding skills so I wanted to get guidance from
    someone with experience. Any help would be enormously appreciated!

  16. Woah! I’m really enjoying the template/theme of this website.
    It’s simple, yet effective. A lot of times it’s hard to get that “perfect balance” between superb usability
    and visual appeal. I must say you’ve done a very good
    job with this. Additionally, the blog loads extremely quick for me
    on Opera. Outstanding Blog!

  17. Greetings from Florida! I’m bored to death at work so I decided
    to check out your site on my iphone during lunch break.
    I really like the knowledge you provide here and can’t
    wait to take a look when I get home. I’m shocked at how quick your blog loaded on my mobile ..
    I’m not even using WIFI, just 3G .. Anyhow, very good
    site!

  18. This design is spectacular! You definitely know how to keep a reader entertained.

    Between your wit and your videos, I was almost moved
    to start my own blog (well, almost…HaHa!) Wonderful job.
    I really enjoyed what you had to say, and more than that,
    how you presented it. Too cool!
