Improving driver warnings accuracy using low-cost sensors

The weather monitoring is currently performed by very expensive professional weather stations. They collect information and they are able to process the data, catalogue weather statistics and even provide predictions about the expected conditions in the near future. However, these warnings have a series of disadvantages: they are very general, they cannot be detailed on small geographical areas, and it is hard for the information to reach the drivers if they are provided in short time. The solution proposed in this paper takes advantage of the new intelligent cars and the inter-connection between them: a low-cost weather sensor can be mounted in each car and will record periodically the weather status, GPS position and time. The car2car communication performed via LI-FI technology is used to send the information to all cars within an area and inform drivers of risky situation.
