I recently got a Garmin vehicle GPS and wanted to add some redlight camera placemarks. Redlight intersections are more dangerous because in most installations they shorten the yellow time to increase revenue. There have been many cases where judges found this to be true and that the yellow time violated sound engineering practices because it was too short. This causes drivers to panic and rush through the intersection causing accidents. Several studies have confirmed that accidents increased after the installation of redlight cameras. For this reason knowing where they are and either avoiding them or being extra vigilant is prudent.
I searched and found people charging for this, being cheap I decided I could do it myself and save the money. Being nice I decided I would make this available to everyone, for free.
I have broken the files into individual states, with California being broken into Northern and Southern somewhere around Bakersfield. My GPS could not handle the larger files and Google Maps appears to stop processing at 1000 records. My database has over 5000 unique entries.
I have the following types of cameras:
The Garmin GPX files contain a proximity alert at 0.1 miles (about 160 meters). This should be enough warning. There is no proximity ability that I know of with KML files and for good reason, Google Earth and Google Maps are not designed to be used as a navigational system like a GPS.
