Abstract

Bus service is easily adjusted to accommodate the changed demand. Despite the flexibility of that, its relocation should overcome the following problems: first, Bus line rearrangement should consider the balance between the demand and the supply to enhance the transit equity among the users scattered around the area that supply against demand imbalances. Second, the existing demand analysed is to crude since the demand was analysed based on TAZ. mainly based on the Dong unit. Utilization of the GWR and GIS-T data can resolve the problem. In this paper, the limitation of the conventional transit demand analysis model is overcome by deploying the GWR model which identifies the transit demand based on the geographic relation between the service location and those of the users. GWR model considers the spatial effect of the bus demand in accordance with the distance to the each bus stops using SCD(Smart Card Data) and BIS(Bus Information System). This demand map was then superimposes with the existing bus route which identified the areas where the balance between demand and supply is severly skewed. since the analysis was computed with SCD and BIS at every bus stops. the shortage and surplus of bus service of entire study area could computed. Further. based on this computational result and considering the entire bus service capacity data. Bus routes optimization from the oversupplied areas to the undersupplied area was illustrated thus this study clearly compared the benefits the GIS.

버스노선은 수요에 대응하여 탄력적인 노선조정이 가능하다. 다만 버스의 노선 조정은 다음과 같은 문제점의 해결이 선행되어져야한다. 첫 번째, 현재 버스 노선 배정의 가장 큰 문제점은 버스의 이용현황을 적절히 고려하지 못한 점, 중복노선 문제 등 수요에 대비한 공급의 불균형을 들 수 있다. 두 번째, 버스이용은 지리적 공간 내에서 일어나는 상호작용 있어서 동단위로 교통 수요를 예측함으로써 교통 수요가 세분화 되지 못한 문제점이 있다. 이러한 문제점들의 해결방안으로 GIS-T Data 및 지리적 가중 회귀분석을 통한 버스 정류장, 버스 노선의 버스 잠재 수요를 파악하고 공급 현황을 분석하여 버스의 수요와 공급의 균형여부를 파악함으로써 효율적 버스 노선을 구축할 필요가 있다. GWR모델을 이용하여 공간적 수요관계를 도출하였다. 공간효과를 고려한 GWR모델을 통해 SCD와 BIS data 이용한 버스 수요를 예측하고 공급과 비교하여 공급 부족을 파악하였다. 전체노선의 노선 과잉지과 부족지역을 파악하였다. 이를 통해서 추가 노선배정이 필요한 곳을 분석하여 버스 최적화를 도모와 GIS의 장점인 시각화를 시도하였다.
