We make about 1,400 decisions in one hour of the day, which makes about 35,000 decisions in 24 hours. The driver's task in traffic is to assess traffic situations and act in accordance with their decisions in traffic. One of the most common causes of traffic accidents is "misjudgment of road users". The perception of space is one of the prerequisites for safe and successful driving. In order to investigate the mentioned issue, the authors of this paper conducted an experimental study with the aim of determining what affects the perception of the distance to the object. 164 respondents participated in the experiment. The research results show statistically significant differences in the perception of distance to objects of different colors. The respondents with the smallest error estimate the distance to the red object better, in the conditions when the driver sits in the driver's seat and observes the object through the camera in the vehicle (hereinafter via the camera), while the respondents in the situation when the driver sits and observes the object in the rearview mirror (hereinafter to the text by looking in the rearview mirror) and in the situation when the driver is sitting and looking at objects over his shoulder (direct observation) estimated the distance to the yellow object with the smallest error. Respondents with the highest error estimate the distance to the blue and green objects.

Analysis and Determination of the Lateral Distance Parameters of Vehicles When Overtaking an Electric Bicycle from the Point of View of Road Safety

Recent years have witnessed an increasing number of electric bicycles on the roads and a rise in the number of road crashes involving e-bicyclists. There are various causes of road crashes involving e-bicyclists. Out of the total number of fatalities in traffic, bicyclists account for 9% in the Republic of Serbia. Road crashes occurring when motor vehicles overtake bicyclists make up 13% of the total number of road crashes involving bicyclists. Having in mind the above-mentioned, an experimental...

Do Statistics Show Differences between Distance Estimations of 3D Objects in the Traffic Environment Using Glances, Side View Mirrors, and Camera Display?

The driver’s task in traffic is to evaluate traffic situations and act in accordance with the estimate. One of the most common causes of road crashes is “incorrect estimated of the traffic situation”. Correct perception of surroundings is one of the prerequisites for safe and successful driving. To investigate the mentioned issue, the authors of this paper conducted an experimental study with the aim of determining what affects the estimation of the object distance. In contrast to previous studies...

Estimation of motorcycle movement speed, by traffic participants, depending on the (not) use of daytime lights

Previous research in the world, as well as in the Republic of Serbia, was aimed at researching the impact of (not) using daytime running lights, in passenger vehicles, on traffic safety. Research on the impact of the (non) use of daytime running lights by motorcycles on traffic safety has been scarce. Bearing the above in mind, as well as the fact that the occurrence of traffic accidents is influenced by many factors, the authors of this paper decided to conduct an experimental study on a driving...

The importance of using a retroreflective vest for the Е-bicycle speed perception

Logistic center’s location for goods distribution in Republic of Srpska can be asserted on many parameters from whom two has vital importance: geographical position and size of traffic flow. Special significance of these center’s are logistical diversity, especially where different branches of traffics are involved. Starting factors for developing such a center in Republic of Srpska are position on roads, rails and corridors. Main purpose of these centers are command gathering, sendig commands to...
