Automatic Speed Control of Vehicle at School Zones Using Raspberry Pi
Abstract
Nowadays people are driving very fast, accidents are occurred more frequently, we loss our valuable life by making small mistake while driving. So to avoid such kind of accidents, it is necessary to alert the driver and to control the speed of vehicle automatically. The main objective of this project is to develop signaling unit to indicate the type of zone to the vehicle and to control the vehicle speed. Every zone like school, highway and etc may have a RF based transmitter tag to transmit the zone information. This signal should be received by the vehicles and accordingly varies the speed limit of the vehicle. In practical, an actuator may be used to control the throttle of the vehicle. But to show the demo module here we used a DC motor,
The project is built around Raspberry Pi. Here we are using a pair if RF transmitter, receiver pair to track the particular school zone and automatically reduce the vehicle speeds. This information will be displayed on 16X2 LCD. At each and every speed limiting zone it is placed with RF transmitter and vehicle consists of a receiver to track and automatically reduce the speed limit in vehicles. Once it crosses the particular area automatically it gains normal speed. We are using a DC motor for symbolic representation of vehicle.
The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation . The Raspberry Pi has a Broadcom BCM2835 system on a chip which includes an ARM1176JZF 700 MHz processor Video Core IV GPU and was originally shipped with 256 megabytes of RAM, later Upgraded to 512 MB. It does not include a built-in hard disk or solid-state drive, but Uses an SD card for booting and long-term storage.
