Periodic timetable is designed as a new, more accessible and efficient system for organization of passenger rail transport that does not require a large investment interventions. It offers possibility for much needed regularity in Croatian public railway transport supply. Considering the current condition of Croatian railway system and its environment this approach appears to be the most efficient. Primary features of periodic timetable are its readability for the final user and symmetry as it thus seems more attractive and efficient. The principle of periodic time table itself ensures systematization of operations in stations and therefore provides improvements to the safety standards. With its transparency this type of timetable also greatly contributes to the quality of services and thereby increases the chance among competitors in a growing market of railway operators.
The paper refers to the identification of technical and technological parameters of the track infrastructure as a function of periodic timetable for the regional passenger transport system of Croatian Railways. The outcome of the research aims to possibilities of gaining productivity through more rational use of resources, namely rolling stock, but also through cohesion of the network. The further benefits will be setting grounds for implementing timed connections to other modes of urban transport, thus, integrating time tables [3]. This will propose the much higher level of service which will have the railway passenger transport in its core structure
