Optimizing Fleet Operations Through GPS Tracking
Global Positioning Systems (GPS) was originally developed by the US Armed Forces to help with naval and overland navigation. GPS uses a constellation of satellites to beam down encoded time signatures to receivers on the surface. By tracking the delay between when the time code says the signal was sent and when it actually arrived, GPS uses Einstein’s theory of relativity and four signals (three if altitude is known) to provide accurate tracking down to about two meters. GPS technology has been moving into the commercial sphere from the military since the 1990s.
GPS fleet tracking systems are used in public transportation, most notably school buses in Kansas City and New York City. These systems allow school districts to know exactly where each bus is, thus improving the safety of their passengers. On flex routes, GPS gives drivers some leeway in adjusting their course to avoid traffic congestion. The secondary benefit is that it allows the school districts in question to better assess idle times, better routing algorithms and fuel efficiency. School officials and parents have a peace of mind knowing that the school buses are monitored constantly.
