btmoore4 - Benjamin Moore pendavi2 - Vasil Pendavinji Directional Driver Hazard Advisory System Problem Statement: Traffic hazards are often only visible to cars immediately around them, therefore it is important to react not only to cars directly in front of you but also several cars ahead. For example, in the event of an accident, cars unaware of the upcoming hazard can pile up causing an even bigger accident. Our Project: Our project aims to detect hazards and directionally communicate with drivers coming up on a hazard in order to keep drivers safe. Our system will propagate information, using IR transmitters and receivers, through several cars in order to keep drivers informed of potential advisories through audio cues. Some hazards, like rapid deceleration or hard swerves could be automatically detected and propagated backwards. In addition to those automatically detected, the passenger will be able to put up advisories for less immediate hazards, such as road obstructions, stopped cars, or accidents. Our competitors would be CB radio and apps like Waze. Our system differentiates itself in that it will respond to hazards automatically, unlike Waze which is meant to be used by a passenger, and propagate directionally as to prioritize drivers behind the hazard rather than in front of it. Descriptions of components: Receiver/transmitter: we would like to use IR as our communication medium in order to limit communication to the car in front of or behind the sender. Each car would have an IR receiver in the front of the car with a transmitter mounted near the rear. Display: a small (~1-2 inch) display will be mounted to display low priority advisories. Controller: a low power microcontroller would be used to control the screen, send and receive messages, play audio cues, and interface with the IMU. User input panel: we will have a strip of roughly 5 buttons, each with a message mapped to it, so that the user can put up less immediate advisories. IMU: an IMU will be used to detect rapid deceleration in order to trigger automatic messages Speaker: a speaker will be used to provide sound cues during a hazardous situation Power: the device will be powered from the car’s 12v source, brought down to 5v or 3v (depending on our choice of microcontroller) using a linear voltage regulator. Test of Functionality: Sending and Receiving Messages at least 100ft. Detect rapid deceleration of equal or more than 15 feet/second2*. * (Ideal deceleration for car/truck under ideal conditions - http://nacto.org/docs/usdg/vehicle_stopping_distance_and_time_upenn.pdf) |
