This project deals with the problem of detecting a vehicle’s speed on highways. The purpose of the project is to create a device that will be able to identify vehicles and calculate their speeds automatically.
Speed trap is a device used by the law authorities in order to check that vehicles are complying with the speed limit in force on roads. Today there are several types of speed traps, but our project strives to offer a better product in every single way: cheaper, safer, more accurate, more reliable and more independent.
Our solution is based on positioning two sensors (accelerometers) underground in a distance of 3 meters away: by measuring the time it takes a vehicle to pass by these two sensors – we could simply calculate its speed. These sensors (here in after, wisdom stones), built as a part of a previous project in order to monitor roads’ status, are actually the basis of our project, where the idea is to use these stones and to add them more functionality for the purpose of speed detection.
The results have shown us that the system is able to identify an event of a vehicle passing by these wisdom stones, and to sample the signal intensity created by the vehicle. Using these samples, it is possible to calculate the vehicle’s speed. Our main conclusion is that with further work, it will be possible to identify vehicles automatically and calculate their speed using the wisdom stones.
