TLDR
In this paper, the authors proposed a buffer time concept based reliability measurement framework using AVL data, which can disaggregate service performance to a high level of detail, and developed three example indicators for applications of reliability assessment (operators), journey planning (passenger) and value of time (agencies).Abstract:
Reliability of transit service has been recognized as a significant determinant of quality of service. Numerous indicators have been proposed by individual operational organizations and the research community dependent on specific objectives and resource constraints. Buffer time based indicators are highly desirable since they enable evaluation of the reliability impacts on passengers from an operational approach. However, buffer time indicators can underestimate passengers perceived reliability performance and hide the sources of observed changes in reliability if the buffer time is based on the total travel time distribution. Large samples of disaggregated data, benefiting from Automatic Vehicle Location (AVL) system, provide great potential to measure reliability at very high levels of resolution. The paper proposes a buffer time concept based reliability measurement framework using AVL data, which can disaggregate service performance to a high level of detail. The framework working procedure is illustrated in the case of AVL data from Brisbane. Three example indicators for applications of reliability assessment (operators), journey planning (passenger) and value of time (agencies) are developed to fulfil different stakeholders’ requirements.read more

A New Strategy For The Diagnosis Of The Bus Headways Using AVL Data
Ilgin Gokasar,Yigit Cetinel +1 more
TL;DR: Kurtosis measurement on headway distribution of 5-minute data can provide online problem detection without using historical data each time step and can be easily followed to create a tool that signals operators for problems without investigating each route perpetually.

The valuation of reliability for personal travel
TL;DR: In this article, the authors review progress made towards a general theory of the traveller's valuation of travel time reliability, and give some indication of recent empirical research in this area, bringing together a large number of theoretical and empirical results, many of which are only partly in the public domain.
