Abstract

As more populations are getting older, the number of vulnerable pedestrians is increasing, thereby social problems related to transportations also frequently occur in different areas and situations. Many of such problems come from bus drivers who may pass bus stops not recognizing passengers about to board. In this paper, we propose a new IoT bus notification system developed to avoid these situations. Our implementation aims to gain bus service routes using publicly opened data, notify passengers about bus stop locations using GPS information and finally deliver the positions of those passengers to the bus drivers so that they can hardly miss passengers who are willing to board on the right stop. By creating an application, it was conducted by means of a GPS to communicate the location of the vehicle by means of GPS and transfer data to the location of the vehicle. Experimental results show that it is possible to accurately determine the position of passengers even in a crowded race area. The average error distance is 31m, and if the data to be processed as error is excluded, it provides a high reliability as 19m.

고령화 사회가 다가옴에 따라 교통약자가 증가하는 추세이며, 이에 따라 대중교통에 대한 문제점은 다발적으로 발생하고 있다. 발생하는 대부분의 문제점은 버스 운전기사가 탑승할 승객을 인지 못하고 정류장을 지나치는 것이다. 본 논문에서는 이러한 문제점을 해결하기 위해 IoT기반의 버스 알림 서비스 시스템을 개발하였다. 개발한 시스템은 공공데이터를 이용하여 버스 노선을 확보한 뒤 GPS정보를 이용하여 사용자에게 정류장 위치를 알려주고 버스 운전기사에게 탑승해야하는 손님의 정보를 전달하는 시스템이다. Application을 만들어 각 지역별로 실외에서 실제 움직이는 차량의 위치를 GPS로 수신한 후 데이터를 전송하는 방법을 통해 연구를 진행하였다. 실험 결과 사람이 많은 경기지역에서도 승객의 위치를 제대로 판별하는 것을 확인할 수 있었으며, 평균오차거리는 31m 이며, 오류로 처리해야 할 데이터를 제외할 경우 19m 로 높은 신뢰성을 제공한다.
