Improve GPS Speed Tracking Accuracy with Fleet Software
Telematics is often used by fleets to monitor and report on speeding incidents. That can help fleets cut down on unsafe driving and avoid fines and poor fuel economy. So it’s no wonder that fleet managers are keen to know when their workers are driving with a heavy foot.
But what if your GPS is wrong? Confronting one of your drivers about a speeding offense that never happened would be, at the very least, awkward for you, and demoralizing for them.
Is GPS ever wrong?
While GPS technology and the supporting infrastructure (satellite communication, cellular coverage and cloud computing) are continually being improved and becoming more reliable, it’s impossible for any provider to promise a 100% error-free GPS experience. There are simply too many factors beyond their control to make that a reality.
The GPS signal can be affected by extreme weather, obstruction in the form of concrete walls, or a malfunctioning unit. Noise and bias can also affect the accuracy of the location data.
While you can still have confidence in GPS as a reliable method of retrieving location data, like any technology it can be susceptible to external factors that affect data quality. Hearing that might make fleet managers nervous about acting on information they get from the GPS fleet tracking, so why is Telogis Fleet different?
How is Telogis different?
Telogis® understands that dealing with speeding drivers within the fleet can be a sensitive issue. On the one hand you don’t want to have a permissive attitude towards dangerous speeding, but at the same time you want to avoid being too heavy handed or assuming too much, particularly if you’re concerned about the reliability of the information you’re getting.
Keeping this in mind, Telogis has developed its fleet management software to take into account aberrations, while at the same time not letting unsafe drivers “get away with it”. Over the years Telogis has helped many fleets, large and small, significantly reduce incidents of speeding.
Experience, and knowledge of how the technology works in the real world, has helped them build a solution that can accommodate possible nuances in data quality while giving fleet managers an accurate and reliable picture of driver behavior.
Consider some ways Telogis telematics has overcome the obstacles of managing speeding using GPS data.
Telogis and GPS — A more reliable result
While GPS can be affected by external factors such as weather, buildings or signal noise that may interfere with the information being transmitted, there are things Telogis has done to improve its reliability and the accuracy of the information you receive. Part of that involves allowing for possible errors in GPS data and applying some real world human logic to deliver the most accurate result.
To help explain this, consider another aspect of GPS data — navigation. When a vehicle passes through a tunnel a personal navigation device (PND) can no longer receive the GPS signal from a satellite, so it’s programmed to allow for that and use other methods of plotting the vehicle’s course, such as the intended destination, stored map data and dead reckoning techniques. In this way, the software makes up for the shortfall of the GPS technology.
When it comes to speeding, Telogis Fleet™ makes sure certain criteria are met before issuing an alert. Sometimes this involves simple techniques to eliminate bogus data, such as making sure the vehicle ignition is on and that there is a strong GPS signal.
Telogis Fleet also offers fleet managers a range of user-defined settings that allow them to choose how aggressively they want to monitor speeding and for which drivers, vehicles or crews. For example, crews working in built-up areas with schools nearby may need to be extra cautious when it comes to speeding.
A combination of software smarts and user control means Telogis users get a system for speed-monitoring that has been tested in the field, one they can confidently rely on. And over the years that system has proved to do exactly what it’s meant to do — create safer fleets.
