Abstract
The aim of this study is to develop a framework for investigating a comprehensive set of Key Performance Indicators (KPIs) for the assessment of railway Intelligent Transportation Systems (ITS). The framework is established through four main steps: (1) development of a comprehensive set of KPIs for railway ITS; (2) validation of developed KPIs and collection of judgments from experts through a Delphi questionnaire; (3) evaluation of KPIs weights for assessing railway ITS with the Group Analytical Hierarchy Process (GAHP); and (4) presentation of a SWOT analysis for the developed KPIs by the authors. The results of the framework are presented as a set of 25 indicators for evaluation of railway ITS and their impacts. The framework could be helpful for selecting KPIs of ITS in another mode of transportation. Monitoring of the contributions of ITS towards sustainable railway can be achieved by a developed set of indicators which are classified in accordance with sustainable dimensions.
Highlights
In the context of rail transport, railway inteligentnih transportnih sustava (ITS) are systems working in a synergy of sensors, communications, computing, and intelligent control used for various aspects of rail system management and control, i.e., customer service, planning and scheduling, dispatch, block control, interlock, and speed control
The framework was not used for the identification of KPIs but only for the development of KPIs related to the evaluation of ITS
The developed KPIs were reviewed by twelve experts, seven of which were scholars in the field of rail transport and railway ITS, three experts in the area of transport, and two in the field of ITS
Summary
In the context of rail transport, railway ITS are systems working in a synergy of sensors, communications, computing, and intelligent control used for various aspects of rail system management and control, i.e., customer service, planning and scheduling, dispatch, block control, interlock, and speed control. The effects of ITS can be observed as a decision support tool both in making the right decisions in terms of ITS deployment or development and in recognizing the areas of improvement or evaluation of ITS. ITS impacts could be summarized through a set of comprehensive KPIs. KPIs are indicators used to measure, track, and report the progress towards delivery on effects identified as critical to the success of transportation organization’s goals and objectives. Following the European Union (EU) goals, the ITS action plan [4], and ITS Directive 2010/40/EU [5], certain steps have been made for developing and summarizing a comprehensive set of KPIs of ITS for road transport. This paper identifies a set of KPIs for evaluation of railway ITS and monitoring of their impacts.
