Increasing the share of trips using public transport is a long-term activity that necessitates continuous improvement of the offer. What is crucial here is not only the tangible sphere, measured by objective indicators of punctuality, but also the subjective area of passenger feelings and assessments. The latter is significantly influenced by punctuality, which can be the catalyst for a long-term process of strengthening passenger loyalty and enhancing the public transport experience. The article aims to assess the importance of punctuality against the background of other transport requirements in the opinion of all city residents, with particular emphasis on the views of people using public transport to varying degrees. Research carried out in Gdynia (Poland) showed that punctuality is one of the most important parameters through which residents evaluate the functioning of public transport, regardless of the method of urban travel. Punctuality is of the greatest importance for people who always travel by car and usually by bicycle. Punctuality is the second most important transport requirement for people who always and usually travel by public transport, i.e., the most important segment of public transport users. The research results confirm the high significance of punctuality among residents, irrespective of their mode of urban travel. Punctuality, though just one of the many aspects of the quality of transport services, plays a pivotal role in shaping the overall opinion about the transport system.
