#Problem There are hundreds of cyclists killed in accidents involving a motor vehicle every year. Despite the stronger awareness of cyclists and more bike-only lanes, we are looking for what can be done to help cyclists be more aware of the incoming danger. #Solution Overview Our solution for reducing the number of incidents of cyclists being crashed by vehicles is to carry out related warnings to the vehicles that are behind the bicycle according to the distance and the speed of the vehicle relative to the cyclist. The device uses ultrasonic sensors to calculate the distance of the vehicle and a control subsystem to take the data in a period of time to determine the speed so that it can determine when to trigger the related modes. #Solution Components: ##Sensor Subsystem 1. Multiple sensors used for measuring distance including ultrasonic sensors and doppler radar sensors ##Control Subsystem 1. Using the distance of the sensed object from the sensor subsystem to calculate the distance of the vehicle. The regular timestamp will be activated to take the distance data to calculate the speed of the approaching vehicle. 2. Determining which mode of operation (normal, warning, and danger) to be triggered based on rear distance and relative speed. 3. Choosing the type of alarm according to the mode of operation. ##Processing Subsystem 1. Bluetooth to send data from the control system to a user’s device for users to view the safety level of riding the bicycle. And users can use the web interface to adjust the parameters of detection as they desire. 2. Internal controller for signal processing between the control subsystem. (such as Raspberry Pi) ##Power Subsystem 1. 15V (maybe changed later) rechargeable power supply for the sensor, standard flashing red, and high-intensity white strobe light, and a small horn. #Criterion for Success The device can alarm the cyclist accordingly when a vehicle is approaching. And fellow cyclist or pedestrian would not trigger the alarms. Parked cars and other objects that are not approaching to the back of the cyclist would not trigger the alarms falsely either. |
