Abstract
Throughout the world the reliability of public transport systems is constantly under review. Questions of reliability are particularly applicable to bus services where they share road space with other vehicles. This study used graphical and statistical approaches to assess the reliability of services composing two key route groups in Adelaide. Geographic Information System (GIS) methods were used to locate the service information along the corridor. Using Automated Vehicle Location (AVL) data in conjunction with the published timetables, bus reliability measures were developed. It was found that the majority of services departed within the required tolerances of between 1 minute early and 5 minutes late; however there are significant departures from this trend. Finally, the analysis suggests that the passenger’s boardings and traffic congestion are the key factors that are contributing to the variations in on-time performance of buses at the stop level.
