Im trying to find a good way for tracking vehicles. Its like counting all the vehicles (cars, motor cycle or any vehicles)through a point on the road. Also it needs to count like how many in total and in each direction. It should work well in Nights or in Rain or deosnt matter what ever the condition.
If we go for camera way, its having limitations in extreme darkness (IRs can helpful in some extend) or when a strong light into the lens. So thats just be OK for some demo purpose and not a foolproof solution.
IR transmitter arrays and receiver placed at 4-5 meters above the road at some arches or some sort of things can track. But then the same issue if a strong light and external IR interference. Also Im a very beginner in electronics. So with my very little knowledge I dont think IR is OK or it will work for 5-6 meters.
Next way I got into my mind microwave doppler radar (like HB100). But it can only detect movement at some area. Its not giving any direction or location specific info.
When googling I found another way implemented at some locations like pressure sensor arrays been setup on the road as two lines and based on some analysis it can track. But its not sounds to be a perfect solution.
So I thought about laser (Laser Distance Measure Module) but I have a little worry about its response time and will it work perfectly for the situation.
So any ideas highly appreciated.
