Design of Graphical Bus-stop Board with Crowdedness Degree Indication
摘要
Abstract
According to domestic current situation that electronic bus-stop board is lack of revealing the crowdedness degree, a new graphical one is designed in this paper. A new method on revealing the crowdedness degree based on ultrasonic test technology is proposed. This paper designs an intelligent public bus vehicle equipment combining with Global Positioning System(GPS) and general packet radio service technique. The ultrasonic sensors detect whether there is anyone standing on by ultrasonic test. MCU counts all the sensors which detect the passengers and estimate the crowdedness degree. It develops a graphical electronic bus-stop board. The system implements some functions, such as revealing the crowdedness degree, vehicle tracking, the bus arrival distance prediction, etc. The system carries out many experiments. The results prove that the system is with high reliability, high accuracy of revealing the crowdedness degree and it visually displays the bus location and the arrival distance in the bus-stop board. It meets requirements of Intelligent Transport System(ITS).关键词
