V2V Intersection Collision Warning (ICW)                                                            			           Dec 2016
•	We built an v2v communication framework to add applications that are related to driver assistance and autonomous driving.
•	Apps like automatic emergency braking, lane-following, automated lane changing can be added on this framework. We implemented Intersection collision warning system to demonstrate the working of the framework.  
•	Sensor fusion of compass and GPS module to eliminate any glitches in the positioning reported by GPS module.
•	The ICW system which is demonstrated in the below YouTube link, is an important active safety feature in autonomous driving. It is driver assistance system which warns driver when there is a probability of collision.
•	Can detect Intersection Collision Warning, predict collision time and warn the driver accordingly.
•	Code repo at GitHub: https:/github.com/saii9/Vehicle-Comn-nrf
