Performance evaluation is fundamental to transport analysis and operations. This paper describes a quality evaluation framework based on level of service (LOS) developed for urban public transport in Switzerland. The framework focuses on four key indicators: on-time performance, headway adherence, speed, and passenger loads. The framework allows users to assess service quality at different levels by measuring the indicators at the single element level and aggregating scores over larger sets of elements. Because the number of indicators is relatively small compared with other frameworks, application of the method is easier, but the method also provides less detailed results. An earlier paper presented a conceptual approach for the framework. This paper extends that work by describing the approach in more detail and focusing on calibration of the LOS framework and application of the framework to a real example in Zurich, Switzerland. The research is part of a larger effort designed to develop a consistent multimodal LOS evaluation system for Switzerland. This system would include nonmotorized traffic, public transport, and road-based transport.
