Technology has become a transformative force, reshaping fundamental aspects of our daily lives and significantly improving our quality of life. From instant communications, to the use of artificial intelligence, to access to unlimited information, a path to a more efficient and connected future has been charted.
One of the most notable examples of this technological revolution is the Global Positioning System (GPS). Originally conceived for military purposes, it has infiltrated everyday life in a profound and multifaceted way. Its impact on road safety is particularly noteworthy. By providing accurate directions and real-time traffic updates, GPS has transformed the way we drive, significantly reducing the risk of road accidents and improving traffic efficiency.
Beyond navigation, GPS has found applications in numerous fields, from improving logistics in transportation and distribution to strengthening emergency response and disaster management.
In this blog, we will explore what GPS is, how it works, its applications and how to use it safely, especially when driving.
What is GPS?
GPS is a satellite navigation system that provides location and time information around the world. It is operated by a network of approximately 24 satellites orbiting the Earth, sending signals that are received by GPS devices.
How does GPS work?
To determine its position, a GPS device needs to be in contact with at least four satellites. These satellites transmit signals that are picked up by GPS receivers, allowing them to calculate your exact position using the time it takes for these signals to arrive. GPS accuracy can be within a few meters, but can be affected by obstacles such as buildings or dense foliage.
What are the uses of GPS?
It is commonly used in the field of general and commercial aviation, in commercial, professional and recreational boats, in the field of topography as it is one of the necessary components to determine the best position. Its use is also very common in automobiles to find the best routes and locations of destinations; hikers, hunters, bikers and skiers to name a few, use the system constantly.
There are five main uses of GPS:
- Location: determining a position.
- Navigation: moving from one location to another.
- Tracking: monitoring the movement of objects or people.
- Cartography: creating maps of the world.
- Timing: enabling precise time measurements.
Advantages of using GPS in vehicles
GPS has become an indispensable tool for in-vehicle navigation. It helps drivers find optimal routes, estimates arrival times and can provide real-time traffic information.
From a road safety perspective, the use of in-vehicle GPS systems has proven to be an effective tool for preventing traffic incidents. These systems offer a number of safety-enhancing features for both individual drivers and fleets of vehicles.
One of the main ways in which GPS can help prevent traffic incidents is when they notify drivers of road accidents, traffic jams, road closures, etc., thus alerting them to control their speed and look for alternate routes in a timely manner so that they do not have to make sudden maneuvers that put their safety and that of others at risk. These notifications serve as constant indicators of safe driving practices, encouraging compliance with speed limits, careful braking and responsible lane changes.
In addition, GPS systems and other related applications collect detailed data on driver behavior, such as hard acceleration, hard braking or abrupt lane changes. With this data, targeted training programs can be developed to improve specific areas, resulting in more engaged and responsible drivers. Driver accountability is also enhanced by tracking data, which increases the likelihood that they will adopt safer driving practices.
Likewise, the implementation of GPS tracking technologies in fleet vehicles can be an effective measure to prevent traffic incidents. GPS devices enable real-time tracking of vehicle location and activities, help identify and address unsafe driving behaviors, and provide visual evidence in the event of incidents. This not only improves workplace safety, but also protects employees and mitigates potential road accidents.
When is a GPS a distractor that can cause traffic incidents?
Despite its benefits, the use of GPS can be a distracting factor and contribute to traffic accidents. The use of GPS navigation systems while driving can increase the risk of cognitive, physical and visual distraction.
According to a study conducted in the United Kingdom, the use of personal navigation devices (PNDs) can significantly affect drivers’ gaze behavior during real-world driving scenarios. The study observed changes in the duration and/or number of glances to specific areas of the driver’s visual field, especially when maneuvering through complex intersections. These changes imply increased distraction and, therefore, a potential increase in the risk of traffic events.
This phenomenon is due to the fact that drivers may need to look longer and more frequently at the navigation device to receive visual instructions, which diverts their attention from the road. In addition, manual interaction with the device may also contribute to physical distraction. Therefore, it is crucial that drivers use navigation devices responsibly and safely, setting their routes before starting to drive and preferably using voice instructions to minimize the need to take their eyes off the road.
How can I safely and efficiently use GPS?
The safe and efficient use of GPS in cars involves a series of practices and considerations to maximize safety and minimize distractions. Below, we suggest some actions you should follow to use GPS safely in vehicles:
Schedule the route before starting your journey: Before starting your trip to an unfamiliar location, enter the address into your GPS while the vehicle is parked. This allows you to concentrate on driving without having to interact with the device on the move.
Familiarize yourself with the route: If you are traveling to a place with several exits or complex junctions, check the map and directions on your GPS beforehand. This way you can anticipate important maneuvers.
Use voice commands: Activate the voice function of the GPS to receive audio instructions without having to look at the screen. If you need to make route changes, use voice commands instead of manually manipulating the device.
Position your GPS properly: Place it in a position where it is easily visible without obstructing your view of the road. A good place might be in the center of the windshield, at eye level, or on a bracket on the dashboard where it is within easy reach without distracting you from driving.
Stay alert and act calmly in response to notifications: If you receive an unexpected notification or route disruption, such as a traffic jam, don’t try to interact with the GPS while driving. Instead, if necessary, pull over in a safe place to review the information.
Be aware of the situation and the roads that the GPS marks for you: Although the GPS is a useful tool, always prioritize traffic signs and road conditions. If the GPS suggests a route that seems unsafe or incorrect, trust your judgment and drive according to actual conditions.
Be cautious of arrival time predictions: GPS often estimates your arrival time, but it is important not to rush or drive recklessly to meet these times. Safety is always more important than punctuality.
Planning your trips and roadside stops: On long trips, use GPS not only for navigation but also to plan rest stops, gas stations and restaurants. This helps you better manage your trip and avoid fatigue.
Your safety and the safety of others comes first. Road safety is everyone.
