Abstract

As interest in green growth picks up, the importance of bicycles which are an environment friendly means of communication has been magnified. However, bicycle routes which are the base of bicycles are designed without considering topographic elements and thus many users are experiencing inconvenience in using bicycles. The present study presents a routing technique to select optimal routes when selecting routes in commuting to school utilizing bicycles. To this end, a formula for optimum route calculation considering slope and intersections was drawn and a method to select optimum routes by applying modified Dijkstra Algorithms was studied. According to the results, the bicycle routes for commuting to school should be selected by the shortest time rather than the shortest distances to the destination, because it required reach the destination faster. Therefore when selecting the routes, it must be based on the shortest time considering waiting time due to crosswalks or crossroads and speed variations due to slopes.

녹색성장에 대한 관심이 높아지면서 친환경 교통수단인 자전거의 중요성이 증대되고 있다. 그러나 이에 기반이 되는 자전거도로는 지형적 요소를 고려하지 않고 설계되고 있어 실제 많은 이용자가 자전거를 이용하는데 불편함을 겪고 있는 실정이다. 본 연구는 자전거 활용에 있어서 통학에서 경로선택을 할 때 지형적 요소를 고려한 최적 노선을 선택하는 경로기법을 제시한다. 이를 위해 최적경로의 연산에 있어서 경사도와 교차로를 고려한 식을 도출하였으며, 변형된 다익스트라 알고리즘(Dijkstra Algorithm)을 적용해 최적 노선을 선정하는 방법에 대하여 연구하였다. 분석결과, 통학용 자전거도로는 목적지까지 신속하게 이동하기 위해, 목적지까지의 이동거리보다는 최단시간에 의해 선정되어야한다. 따라서 노선을 선정할 때 횡단보도나 교차로에 의한 대기시간과 경사에 의한 속도증감을 고려한 최단시간 노선을 기준으로 해야 한다.
