Travolution — An embedded system in passenger car for road safety Each year, there are thousands of highway deaths and tens of thousands of serious injuries due to “Run-Off-Road” accidents. Everything from simple driver inattentiveness, to fatigue, callousness, to drunk driving, is responsible. Simple sensors can be fitted inside vehicles embedded with various features like, automatic collision notification, vehicle security, speed control which can give impetus to an efficient road safety system. The features that are proposed in this work are: Automatic collision notification that gives notification to the victim’s relative, Red light traffic control makes sure vehicle doesn’t break signal, Speed control alters speed in different zones, Horn control prevents honking in horn prohibited zone, Alcohol detection detects drunk driving and Vehicle security is used to prevent theft.
