The main goal of the entire project was so to investigate problems of daily commuting of workers, pupils and students, especially from the modal split point of view. The project is structured in two parts.The first part of the book is an extensive analysis of modal split by different relations (routes) and groups of commuters (pupils, secondary school pupils, students and workers). We tried to establish the areas in Slovenia where the usage of public transport is the weakest and to provide credible causes of that. The data of modal split was compared with the supply of public transport and with this we established that there is a significant link between the high public transportation usage and the high quality and competitiveness offer of public transportation vis-à-vis personal transportation.The next chapter was dedicated to particular pilot areas where the supply of public transport was greatly improved (Dol pri Ljubljani, Ankaran, Idrija, Nova Gorica). With the method of field interviewing and passenger counting we found out that the greatly improved offer of public transport does not necessarily cause a greater demand for public transport and thus the shift towards a more sustainable mobility.The synthesis of the book is in ten recommendations of possible transport policy measures for the purpose of achieving more sustainable mobility patterns with workers and students.Knjiga prikazuje problematiko dnevnih potovanj šolarjev in delavcev v Sloveniji, zlasti z vidika izbire prometnega sredstva. Prvi del knjige analizira način prevoza na posameznih relacijah in po posameznih skupinah dnevnih vozačev (osnovnošolci, srednješolci, študenti in delovno aktivni). Ugotavljali smo, na katerih območjih in na katerih relacijah v Sloveniji je uporaba javnega potniškega prometa najšibkejša in skušali podati razloge za to. V drugem delu publikacije so obravnavani primeri dobre prakse na nekaterih območjih, kjer je prišlo do precejšnjega izboljšanja ponudbe javnega potniškega prometa (Dol pri Ljubljani, Ankaran, Idrija, Nova Gorica). Sintezna spoznanja so podana kot priporočila za pripravo možnih ukrepov spodbujanja bolj trajnostnih oblik prevoza na delo in šolo.
