Abstract

Punctuality of bus operation can be defined as "timely operation of buses according to their operation schedules." It tis often considered as one of the important measures of bus operation reliability in evaluating bus operation performance from the viewpoint of bus users. Passenger waiting times are severely influenced by the punctuality of bus operations. However, there exist many situations that predetermined schedules cannot be met. In these cases, other definitions of punctuality should be given. This paper is to develop punctuality indexes of bus operation based on various bus operating situations. Bus operation data sampled from Seoul bus system were analyzed to calculate punctuality indexes for a number of bus routes. Then, bus operation punctuality was characterized by various operating conditions. Several interesting results were obtained and explained.

버스 운행 정시성은 운행계획에 따라 정시에 운행하는 정도를 나타낸다. 이용자의 대기시간은 버스 운행의 정시성에 직접적으로 영향을 받기 때문에 정시성지표는 이용자 관점에서 버스 운행의 신뢰성을 평가하는 지료로 가장 널리 사용되는 평가척도 중 하나이다. 그러나 실제 버스 운행은 도로여건, 교통상황, 승객수요 등 여러 가지 상황에 의해 사전에 작성된 운행 계획을 준수하지 못하게 된다. 따라서 여러 가지 상황에 따라 버스 운행의 정시성을 평가할 수 있는 정시성 지표를 개발하여 제시한다. 또한 서울시에서 운행하는 여러 버스 노선의 운행 자료를 분석하여 정시성 지표를 산출하였으며 이를 통해 여러 가지 운행 여건에 따른 정시성지표의 변화 특성을 분석하였다.
