i dont have any.
thats life in a small town.
i can imagine how frustrating it can be.i hate sitting at any lights when i go to the city,i end up there every couple weeks.
the sensors are usually sensitive enough to pick even a set of keys.
our park traffic counters pick up vehicles 30 feet away.
problem is,computers are involved,so all the protocals need to be met before a ligt will change.
