The Influence of the Duration of Journey Stages on Transport Mode Choice: A Case Study in the City of Tarnow

In this paper, we present the effect of making too many private car journeys on city transport systems. A sustainable approach for the development of transport infrastructure is needed, which takes into account local conditions and needs, especially for areas with a high density of origins and destinations. The criteria for evaluating public transport and bicycle transport are presented, which, if acceptable to city residents, may lead to changes in transportation behaviors and, thus, a more efficient use of transport in daily travels. Factors affecting the mode of transport choice include the duration of particular stages of a journey, such as reaching the location where the first ride commences/driving from the travel origin, waiting for a vehicle (bus journeys) or ride/drive, and reaching the travel destination of the last ride/drive. Additionally, the possibility of using a car and having a seasonal ticket for public transport were taken into account. In this study, the results of detailed travel research in the Polish city of Tarnow were used. It has been proven that the low share of public transport in daily travels is due, among other things, to excessive time to reach a stop and due to walking to journey destinations, whereas the low share of cycling is mainly due to a lack of comfort and safe cycling infrastructure.
