The impact of driver age on their visual perception of the environment
No full textVizualna percepcija počinje ulaskom svjetla u naše oči i pretvorbom u električne impulse, koji se prenose do mozga gdje se obrađuju. Niz čimbenika utječe na vizualnu percepciju vozača kao što su starost, vozačko iskustvo, spol vozača itd. Starost značajno utječe na vizualnu percepciju s obzirom na to da se prilikom starenja narušava kvaliteta vizualnog sustava te se smanjuju psihofizičke osobine. Cilj ovog rada je istražiti na koji način starost utječe na vizualno uočavanje okoline tijekom vožnje. U istraživanju je sudjelovalo 20 dobrovoljaca od kojih je 10 bilo mladih, a 10 starih vozača koji su odvozili zadanu rutu na simulatoru vožnje. Sudionici istraživanja nosili su naočale za praćenje pogleda (Tobii Pro Glasses 2) kako bi se utvrdili uzorci i razlike između vizualnog uočavanje okoline između mladih i starijih vozača. Rezultati podataka su pokazali kako su mlađi vozači više usmjeravali svoj pogled na prometne znakove, a manje na reklame.Visual perception begins with light entering our eyes and converting it into electrical impulses, which are transmitted to the brain where they are processed. A number of factors affect the driver's visual perception, such as age, driving experience, driver's gender, etc. Age significantly affects visual perception, given that the quality of the visual system deteriorates during aging and psychophysical properties decrease. The aim of this work is to investigate how age affects the visual perception of the environment while driving. 20 volunteers took part in the research, 10 of whom were young, and 10 were old drivers who drove a given route on a driving simulator. Research participants wore eye-tracking glasses (Tobii Pro Glasses 2) to determine patterns and differences in visual perception of the environment between young and older drivers. The results of the data showed that younger drivers focused more on traffic signs and less on advertisements
Logistics Process Planning Overview
No full textLogistički procesi obuhvaćaju različite aktivnosti poput upravljanja zalihama i opskrbnim
lancem, planiranjem transporta i distribucije, implementaciju tehnologija za bolje upravljanje
skladištem i transportom, nadzor nad ljudskim resursima i slično. S obzirom na količinu
elemenata obuhvaćenih logističkim procesima, planiranje istih opsežan je i kompleksan posao
stoga nije moguće primijeniti jedinstvenu metodu planiranja logističkih procesa u svim
situacijama i poduzećima. U radu su prikazane različite metode planiranja logističkih procesa
koje za cilj imaju optimizaciju troškova, vremena i kapaciteta, kao i primjeri dobre prakse.Logistics processes encompass various activities such as inventory and supply chain
management, transport and distribution planning, implementation of technologies for better
warehouse and transport management, supervision of human resources, and more. Given the
number of elements involved in logistics processes, planning them is a comprehensive and
complex task, making it impossible to apply a single method for logistics processes planning
in all situations and companies. This paper presents different methods for logistics planning
with a goal of optimizing costs, time, and capacity, along with examples of best practices

zakonima, normama. Cilj tih metoda je osigurati zaštitu svih sudionika zračnog prometa i trećih
osoba. Svi putnici, osoblje i osobe koje nisu putnici podložni su zaštitnom pregledu ako žele
stupiti u zaštitno ograničeno područje zračne luke. Prtljaga čija je osnovna podjela na ručnu i
predanu isto tako podliježe zaštitnom pregledu koristeći razne inovativne metode. Kako bi se
ostvarila očekivana zaštita u zračnom prometu postoje zabranjeni predmeti koji se ne smiju
prevoziti u putničkoj kabini ili u teretnim prostorima zrakoplova. Proces prihvata i otpreme
tereta dijeli se na fizički i dokumentarni dio, gdje je zaštitni pregled fizički dio. Zaštitni pregled
tereta provodi se u terminalima.Methods of security screening for passengers, baggage, and cargo are defined by
regulations, laws, and standards. The goal of these methods is to ensure the security of all
participants in air traffic and third parties. All passengers, staff, and non-passengers are subject
to security screening if they wish to enter a restricted area of an airport. Baggage, which is
primarily divided into hand baggage and checked baggage, is also subject to security screening
using various innovative methods. To achieve the expected level of security in air traffic, there
are prohibited items that cannot be carried in the passenger cabin or cargo holds of an aircraft.
The process of accepting and dispatching cargo is divided into physical and documentary, with
security screening being the physical part. Security screening of cargo is conducted at airport
terminals

Application of virtual reality in educating container terminal employees
No full textLučki kontejnerski terminali predstavljaju čvorišta u opskrbnom lancu, odnosno mjesta gdje se
susreću različiti modovi prometa. O produktivnosti kontejnerskog terminala ovisi brzina
prijevoza kontejnera do njihovih krajnjih odredišta. Za funkcioniranje lučkih kontejnerskih
terminala zaduženi su djelatnici koji upravljaju prekrcajnom mehanizacijom i drugim
sustavima na terminalu. Sposobnost djelatnika za obavljanje posla ovisi o njegovoj edukaciji i
treningu. Rad na lučkom kontejnerskom terminalu vrlo je opasan i zahtjeva znanje, točnost,
preciznost i međusobnu koordinaciju djelatnika. Edukacija djelatnika provodi se s pomoću
simulacijskih alata na temelju virtualne stvarnosti (Virtual Reality - VR). Simulacijskim
alatima se djelatnici osposobljavaju za rad na svim dizalicama, prijenosnicima i drugoj
prekrcajnoj mehanizaciji na terminalu u različitim vremenskim uvjetima. Svrha ovog rada je
opisati ulogu djelatnika na lučkim kontejnerskim terminalima, važnost i načini njihove
edukacije. Cilj pisanja ovog rada je analizirati načine edukacije djelatnika i utvrditi važnost
primjene VR tehnologije u usavršavanju djelatnika na lučkim kontejnerskim terminalima.Port container terminals are hubs in the supply chain, they are places where different modes of
traffic meet. The speed of transporting containers to their final destinations depends on the
productivity of the container terminal. The employees who manage transshipment machinery
and other systems at the terminal are responsible for the functioning of port container terminals.
The employee's job performance depends on his education and training. Work at the port
container terminal is very dangerous and requires knowledge, accuracy, precision, and mutual
coordination of employees. Employee training is carried out using simulation tools based on
virtual reality (Virtual Reality - VR). Simulation tools are used to train employees to work on
all cranes, conveyors, and other handling machinery at the terminal in different weather
conditions. The purpose of this paper is to describe the role of workers at port container
terminals, the importance and methods of their education. The goal of writing this paper is to
analyze the methods of employee education and determine the importance of applying VR
technology in the training of employees at port container terminals
The impact of monitoring driver behaviour through telematics devices on road traffic safety
No full textTelematički uređaji igraju ključnu ulogu u modernoj komunikaciji i praćenju podataka,
posebno u kontekstu transporta i transportne logistike. U zadnjih nekoliko godina rastući je
trend praćenja vozila telematičkim uređajima, te analize ponašanja vozača u svrhu poboljšanja
vještina i stila vožnje što postaje jedan od aktivnih čimbenika sigurnosti u cestovnom prometu.
Različiti telematički uređaji prema tehničkim osobinama, vrstama i načinima snimanja podatka
omogućuju praćenje i nadzor ne samo vozača i vozila već i aktivnu dijagnostiku i održavanje
čime se smanjuje rizik od nepredvidivih kvarova. Transportne kompanije mogu koristiti
telematičke uređaje za efikasno upravljanje flotom vozila, što uključuje planiranje održavanja,
analizu vozača i optimizaciju troškova. Smanjenjem potrošnje goriva i optimizacijom ruta,
telematika može doprinijeti smanjenju emisija štetnih plinova.
Telematika ima značajan utjecaj na ponašanje vozača, pružajući alate i metode za
praćenje, analizu i poboljšanje vozačkih navika jer može prikupljati podatke o brzini, ubrzanju,
kočenju i skretanju, što pomaže u identifikaciji rizičnih obrazaca vožnje. Ovi podaci
omogućavaju vozačima da prepoznaju svoje slabosti i rade na njihovom poboljšanju, a dobrom
motivacijom vozača moguće je potaknuti vozače na sigurniju i oprezniju vožnju kako bi se
smanjila mogućnost nastanka prometnih nesreća.Telematics devices play a key role in modern communication and data tracking,
especially in the context of transport and transport logistics. In the last few years, there has been
a growing trend of monitoring vehicles with telematics devices, and analyzing driver behavior
in order to improve driving skills and style, which is becoming one of the active factors of road
safety. Various telematics devices according to technical characteristics, types and methods of
data recording enable monitoring and supervision not only of drivers and vehicles, but also
active diagnostics and maintenance, which reduces the risk of unpredictable breakdowns.
Transport companies can use telematics devices for efficient fleet management, which includes
maintenance planning, driver analysis and cost optimization. By reducing fuel consumption and
optimizing routes, telematics can contribute to reducing harmful gas emissions.
Telematics has a significant impact on driver behavior, providing tools and methods to
monitor, analyze and improve driving habits as it can collect data on speed, acceleration,
braking and turning, which helps identify risky driving patterns. This data allows drivers to
recognize their weaknesses and work on their improvement, and with good driver motivation it
is possible to encourage drivers to drive safer and more cautiously in order to reduce the
possibility of traffic accidents.
