Future ImprovementsDespite the fact that this document discusses various issues to address when implementing a GPS-based autonomous car, I have discovered several issues for this solution to be practical . The first part of the solution is based on retrieving a GPS-based location. Here's the problem. This depends entirely on recovering the visible GPS value, so what if GPS isn't available in the first place? Below are some issues and proposed improvements1. Unavailability of a reliable GPS signal and solutionThis is a problem that occurs many times when the car is in the middle of nowhere. It is quite common to see our GPS system trying to get a location from the satellite. Therefore, if a location is not found, the solution should cache the last known location. This caching should be periodic. Modern cell-based GPS systems use network-provided GPS coordinates to track the car on the globe. So the main idea behind this is to retrieve the last known location from the GPS cache and then implement a network based locator to retrieve the location coordinates. This has proven to be more accurate and has also been implemented by the maps application on Android. So, assuming we have network access based on coordinate access, the car will get better location retrieval. Another thing to remember here is that this is also not 100% reliable, in fact any solution may not always be accurate but the idea is to improve.2. Distance calculation based on compass moduleThe article works on this calculation, d =R • cos−1(sinφ1 • sinφ2 +cosφ1 •cosφ2 •cos(λ2 −λ1))Where R is the radius of the earth and is the distance between two points. Keeping the very low level implementation details aside, let's talk about how... middle of the paper... how when you're in the red. Now, considering the interactions between vehicle and pedestrians, we always need to prioritize the sensor data (for pedestrians) thus controlling the driverless vehicle that collides with pedestrians. The algorithm, which acts as the brain for the autonomous vehicle, should also be able to make decisions about whether or not to apply the brakes based on the speed of the vehicle and the distance to the approaching object. More research can be done on increasing the reliability of the autonomous car. system, such as safety improvements, what the car should do when there is a road block (implement an alternative routing algorithm) or how to handle changing lanes or encountering a detour on the road, these can be numerous other issues. These are all hot research areas at the moment and many ideas are emerging and implemented. But since this topic is considered a solution MUST be found to all these problems.
