Folks,
We live on a "shortcut" that people use to avoid one traffic light in town. I am looking for an UNOBTRUSIVE, inexpensive automated means of recording vehicle speed, direction, and time of day. The road is a paved asphalt unstriped country lane that is approximately 20 feet wide.
My thought was two pairs of garage door obstruction sensors that are mounted fixed distance apart, along the side of the road. Record the time when each light beam was broken. Taking the differnce between the times will give me average speed and direction.
Cost and robustness is important. We are up in the New England portion of the US. I am thinking of using the parallel port of a PC for the data logging.
Thanks
