This paper aims to identify management strategies for the improvement of urban bus services based on travelers' perceptions. A paper-and-pencil-based questionnaire was designed to collect responses from travelers. Priority areas for the improvement of bus services were identified by comparing factor structures and management schemes, which are derived using Revised Importance?Performance Analysis (Revised IPA). The study also aims to identify areas for improvement using conventional IPA and to compare the results obtained from IPA and Revised IPA. It was shown that there is a substantial difference between travelers' stated and derived importance for the travel attributes. The qualitative factors, which are often neglected in improvement planning of transportation services in emerging countries, were identified as major areas of intervention. Although the findings are case specific, the work is likely to encourage policy makers to apply a similar approach for formulating policy measures for improvement of services in other contexts.
