Development of Measurement System for Public Transport Performance

Abstract

Accurate measurement systems of performance are important for all businesses, including public transport. The importance of such systems will grow with the advent of liberalization in the European transportation sector (i.e., the opening of transit service provision for tendering), as service provision contracts will require agreed-on measures for performance and service. This paper describes research on developing a public transport level-of-service (LOS) standards framework for Switzerland. The standards framework is intended to reflect influences on capacity and operational quality in urban road-based transit and relies on four main measures: speeds, passenger loads, on-time performance, and headway adherence. This paper outlines the selection of specific measures for evaluating public transport LOS and the proposed framework. The framework provides a consistent method for evaluating public transport LOS on all levels of analysis, from single elements (e.g., bus stops) to networkwide analysis. The paper also describes how information from automated onboard data collection systems can be used for detailed service analysis. This calibration procedure is illustrated in an example from the Zurich public transport system. Challenges faced (especially with respect to the selection and filtering of relevant data) and future development of the approach are described. While the proposed LOS framework is being prepared for Switzerland, the experience and approach described should help others developing and improving performance management systems for public transport.

Public transport accessibility in metropolitan areas: A new approach incorporating population density

“…A substantial body of research has assessed the relative quality of public transport services, especially in terms of accessibility (Orth et al, 2012;Fu and Xin, 2007). Previous studies have measured different aspects of public transport service levels such as accessibility, mobility, and connectivity.…”

Implementing Design and Operational Measures for Sustainable Mobility: Lessons from Zurich

“…Second, it greatly simplifies the signal control scheme. Third, given that buses in Zurich are highly equipped, and typically adhere to their schedule, it works fairly well in most situations without providing unnecessary priority [30,68,69]. In the case of intersections with a very high public transport demand, however, the transit signal priority scheme might not be feasible.…”

Public transit planning and scheduling based on AVL data in China

“…() proposed a reliability measurement approach based on cellular network data, and compared the results with analysis based on AFC data. In recent years, application of automatically collected data to service measurement has become more common (Barabino et al., ; Orth et al., ; Yetiskul and Senbil, ). Meanwhile, using the data, some research has focused on operation and dispatching strategies, such as holding, to improve reliability (Uniman, ; van Oort et al., ); other research has focused on predicting travelling time (Börjesson et al., ) and improving timetables (Cevallos et al., ; Salicrú et al., ).…”
