Communicate road information to citizens
communicate road information to SatNavs and Phones in order to warn about potential hazards on the road ahead
I reckon that the simplest solution is the following : - gather real-time data from roads, such as average speed of vehicles, presence of traffic jams, roadworks or slow moving vehicles such as tractors. - crunch that data and then send the most appropriate information to a driver's satnav device ( it could also be a phone ). This information could be a recommended speed or potential danger ahead.
People usually make mistakes on the road because they go too fast and don't anticipate anything that is ahead.

アイデアを書くときは、あたかも新しい発明であるかのように書いてください。 「情報を伝達する」という考えはブレインストーミングの一部になる可能性がありますが、インフィニティのソリューションセクションは、概念化の程度があり、新しいシステムやガジェットなどに名前を付けることができるアイデアのためのものです。つまり、「GPSデータに基づいて障害物を警告するSatNav」のようになります。さて、それがどのように機能するかの詳細に入ることができれば、これはインフィニティのアイデアに適しています。 :)
ところで、現在の交通状況は、道路上の携帯電話の所有者からの信号によって、このように正確に推測されていることをご存じでしょう。電話の更新レートが衝突警告システムに十分かどうかはわかりませんが、おそらく、自動車用の特別な機器が必要になるでしょう。
これは従来のレーダーと比べてどうですか？
When writing ideas, write as if hey are new inventions. The thought "to communicate information" can be a part of brainstorming, but on Infinity, the solutions section is for ideas that have the degree of conceptualization, where you can put a name to it, something like a novel system, or a gadget. So, it could be "A SatNav that warns you of obstacles based on GPS data". Now, if you could go into more details of how it would work, this would be good for an idea on Infinity. :)
Btw., I'm sure you are aware that the current traffic conditions are inferred exactly this way -- by signals from the mobile phone owners on the roads. I'm not sure if the update rate in the phones would be sufficient for a collision warning system though, and likely, you would need special equipment for the cars.
How would this compare to the traditional radars?
