What in the world is V2P?

Vehicle to Pedestrians, or V2P, is a safety system that allows pedestrians crossing the path of a vehicle to be warned of a possible collision. Basically, Honda came up with a development from the already existing "Vehicle to Vehicle" network technology that now also alerts cars if they are a possible danger to a pedestrian by monitoring their position and direction using the GPS on their smartphones. When a pedestrian crosses into the scope of the warning algorithm in the car’s computer, then a big warning sign will flash for it to stop. Likewise, if you're that pedestrian that is too busy talking on the phone, texting your best friend or just simply really into a song that just started playing on your iPhone, you will also get a pop up warning alert if a car is approaching a little too close for comfort. The person in the car is also notified that the person is distracted while approaching them, in order for them to take extra caution. This can work for vehicles who cannot see people or motorcyclist coming at high speeds and while being blocked by other vehicles or road blocks. Once a person is on the go with their smartphone, the waves are being sent out to vehicles around them, in order to ensure the safety of the pedestrian and driver.
