A Study of Evaluation Index and Level for Real-Time Bus Arrival Information Reliability

抄録

As a part of a public transportation information provision, the Bus Information System (BIS), which has been recently advocated by the city governments of South Korea, provides bus arrival information and bus location information to users. The reliability index and level are evaluated differently in each city. As the evaluation is performed, without considering prediction size and range, the evaluation result cannot be fed back to the BIS. Therefore, this study derived time range and spatial range of bus arrival information based on the results of a survey. 'User allowed range' and 'User allowed error' can be selected as the range of the evaluation and the level of the evaluation. The accumulation probability of the absolute error can be selected as the reliability evaluation index. Thus, this study showed the methods of selecting evaluation range, index and level for the evaluation of real-time bus arrival information reliability
