Input: (CNN) It's the killer that, by some measures, takes more young lives each year than conflict or some forms of cancer. Every 30 seconds a person is killed in a road crash, according to figures from the Global Road Safety Partnership. That's more than 3,400 people per day and 1.25 million people per year. Perhaps even more arresting is World Health Organization (WHO) analysis which says that 90% of all road based fatalities occur in low to middle income countries, despite such nations having only half of the world's vehicles. It's a tragedy that even takes a toll on development costing some nations up to 5% of GDP, according to the International Road Assessment Programme (iRAP).CrashDetech auto detects road accidentsThe app calls an agent who locates the nearest ambulanceAims to reduce waiting times and save lives
