Opis: Motorcyclists remain a disproportionately large group of vulnerable road users, with fatality rates significantly higher than that in other road groups. Additionally, fatal accidents involving motorcyclists have a more slowly decreasing trend in comparison to that of other road users, while the number of this kind of users is growing fast. For all these reasons, there is a need to understand what the key factors leading to fatal accidents are in order to identify the possible measures to minimize the accidents themselves or at least their consequences. This would permit, indeed, to positively impact the road traffic system, leading to the creation of the safest road traffic system possible, as it is the goal of the Sustainable Safety approach. The aim of this study is to dive into the mentioned problem, analyzing fatal motorcycle accidents in Slovenia over a decade, highlighting the key factors contributing to these incidents. By integrating data from four databases, the study evaluated accident trends, infrastructural elements, and rider behavior through a multi-stage analysis. Firstly, data were collected from four national, up-to-date databases that contain information about road accidents themselves, the road infrastructure, additional police data, and media descriptions. After merging this information into one comprehensive database, where each row represents all the data available for one accident, a general analysis of accidents’ trends over the considered 10-year period was developed, considering at first all fatal road accidents, then deepening it to accidents caused by a motorcyclist, and finally to single-vehicle accidents. A statistical analysis followed, aimed at identifying a statistical correlation between the accidents and the factors leading to them. The results of the first accident analysis indicated that excessive speed, incorrect driving direction, and overtaking maneuvers are the primary causes of fatal accidents, especially on non-urban roads preferred by motorcyclists. Single-vehicle accidents frequently involve collisions with roadside objects, including safety barriers and poles, underscoring the need for targeted infrastructural improvements. The following correlation analysis revealed that a total of seven factors were statistically significant: three human factors (age, gender, experience)—which were the ones with the strongest correlations—one infrastructural factor (pavement width), and three factors belonging to external conditions (accident type, cause, and location). Of these, four were positively correlated to the causer, while three, i.e., pavement width, causes, and road location, were negatively correlated. This study provides a foundation for future research on less severe accidents and proactive risk behavior analysis, aiming to improve motorcyclist safety comprehensively.

Opis: V magistrskem delu je obravnavana problematika prehodnega območja vstopa v naselje, kjer cesta zunaj naselja prehaja v pozidano okolje ob cesti ali v območje, ki ga določajo meje naselja. Osnovni namen ureditve vstopa v naselje je voznika opozoriti o spremembi okolja ter ga spodbuditi k ustrezni prilagoditvi hitrosti, saj se z vstopom v naselje običajno spremenijo prometne razmere (npr. večja količina nemotoriziranih udeležencev v prometu). V magistrskem delu je podan pregled trenutne zakonodaje v Sloveniji in tujini, ki se nanaša na umirjanje prometa. V nadaljevanju je v sklopu magistrskega dela proučena in analizirana obstoječa projektna dokumentacija ter že izvedeni ukrepi na območjih vstopov v naselja. Na podlagi ugotovitev so predlagane tipske rešitve ureditve vstopov v naselja, ki se lahko uporabijo v danih situacijah. Predlagane rešitve so zasnovane z namenom zmanjšanja tveganja za nastanek prometnih nesreč in povečanja varnosti vseh udeležencev v prometu. Upoštevane so smernice, ki jih določa zakonodaja glede prometne varnosti, z namenom, da bi ureditve čim bolj učinkovito prispevale k varnemu in nemotenemu prehodu vozil v naselje.

Opis: V magistrskem delu so predstavljena sodobna načela za načrtovanje večnivojskih vozlišč in priključkov; predstavljen je njihov namen, delitev, sestavni elementi, projektno tehnični elementov in oblike, ob upoštevanju vizij varnosti v cestnem prometu (»vizija nič«, »trajnostna varnost«). Podano pa je tudi načrtovanje avtocest na splošno, kot glavne smeri iz katere se vključujemo ali pa izključujemo na vozlišča in priključke, oziroma izvajamo določene manevre, ki se tičejo večnivojskih križišč.
Ključne besede: večnivojsko križišče, vozliča, priključki, avtocesta, varnost v cestnem prometu

Opis: V tej projektni nalogi se preverja ustreznost stanovanjske hiše glede na toplotne izgube ter kondenzacijo s stenah. Stanovanjska hiša je bila zgrajena v 90. letih prejšnjega stoletja, po takratnih standardih, zato se zdi pomembno preveriti ustreznost, saj so se do danes le-ti konkretno spremenili. Najprej so podani izračuni za toplotno prepustnost posameznih gradbenih elementov, sledijo izračuni koeficientov toplotnega prehoda upoštevajoč toplotne mostove ter Glaserjeva metoda za preverjanje nevarnosti za nastanek kondenzacije v stenah objekta.
Ključne besede: gradbena fizika, toplotne izgube v stavbah, toplotni mostovi, Glaserjeva metoda
