A comparative study of Lane Change Assistance Protocols at Road Network

Driving over road networks is an everyday challenge that several research studies have been proposed to make it more safe and convenient. One of the main issues need to be efficiently and accurately handled is lane change scenarios. Drivers need to change their driving lane to take an exit on a road or to open the way for faster or emergency vehicle on that lane. Changing lane over highway road scenarios is a more serious challenge than changing it on downtown areas. This is due to the relatively high speed moving vehicles there. Vehicles in blind spots and wrong estimations of the distances between vehicles are the main two challenges that en-face drivers while changing their driving lanes. These cases may cause fatal accidents and lead to several damage consequences. This paper aims to investigate and compare the different previous proposed protocols that have been used to control safe lane changing for autonomous vehicles. Moreover, it reviews the intelligent driving assistance protocols that help drivers to safely change their lanes in several scenarios.
