Special Issue Information

Dear Colleagues,

Currently, it is necessary to deal with Road Traffic Safety in close cooperation with the environmental capacity of roads. The whole process must be seen in the holistic synergy of sustainable preparation, construction, and operation of individual elements of the transport process.  The minimally 4-subsystem holistic approach driver–vehicle–road/pavement-sustainability development should be considered.  From the mentioned fact, it is clear that the given Special Issue is an extremely interdisciplinary topic, in which traffic psychologists, car manufacturers, designers and road managers, environmental authorities, and health departments participate. From the perspective of Road Traffic Safety, the limiting factors are above all skid resistance of wearing course, pavement roughness, the presence of water on the road, and the driver's ability to make the right decision. From a geometric point of view, it is important to objectify morphology of the pavement surface, which is divided into four levels (micro-, macro-, mega-texture, and unevenness). However, it should be kept in mind that increasing safety, for example through road retarders, can lead to a deterioration of the environment (noise, dust, vibrations) of residents around city roads, thereby reducing the Pavement Environmental Capacity. Pavement Environmental Capacity represents such a state of roadway operability, assessed through friction, transverse and longitudinal unevenness, surface condition (repairs, voids, lightness, reflectivity), in which the established environmental quality indicators are not exceeded. Individual objects and parts of roads play an important role from the aspect of traffic safety, especially intersections, bridges, and tunnels, which need to be paid extra attention.

Road transport is a source of exhaust and non-exhaust emissions of particulate matter (PM). Non-exhaust PM emissions include road surface wear, tires, brakes and road dust resuspension. An important part of PM in urban air consists of particles that originate from the resuspension of road dust. This study focused on the analysis of the physicochemical properties of road dust and PM10, PM2.5 and PM1 (PMx) in the air (size, concentration, distribution, content of chemical elements), the properties of urban aerosol (number, mass and area distribution), and at the same time, the interconnection between the detected chemical elements in road dust and individual PM fractions in the air in order to reveal the sources of PM in the Žilina City, Slovakia. The presence of various chemical elements was found in road dust, of which the highest concentrations (more than 100 mg/g) were the elements Ca, Si and Al (specifically 373.3 mg/g, 351.4 mg/g and 113.9 mg/g on average from four sampling sites). The concentrations of PM10, PM2.5 and PM1 were, on average, 27.2 μg/m3, 19.5 μg/m3 and 14.5 μg/m3 during the measurement period according to the reference gravimetric method. The chemical elements K, S, Cd, Sb, Pb, Ni and Zn were detected and the most represented (more than 60%) in the fine PM2.5 fraction, and the chemical elements Mg, Al, Si, Ca, Cr, Cu, Fe and Ba were the most represented in the coarse PM2.5–10 fraction. The analysis of the aerosol in the range of 12 nm–20 μm revealed a bimodal distribution of the collected sample of the investigated urban aerosol. This study provides a comprehensive view of the properties of road dust, airborne PM and aerosol (up to the size of nanoparticles), which can contribute to the expansion of knowledge in this field.

This article’s primary goal was to analyze the effect of texture on skid resistance. Surface texture was recorded with a revolutionary device designed to create 3D surface scans, the Static Road Scanner. The skid resistance was represented by a pendulum test value. Measurements were made on three different groups of surfaces. Reference surfaces with known standard grain sizes represented the first group. The second group consisted of specimens made from a different type of aggregate. The last group of surfaces consisted of asphalt specimens made from different sizes and types of aggregates used in a mixture. The test results shed some more light on understanding texture’s effect on surface friction. Although some results were expected, not all of them were proven. For instance, a high level of texture doesn’t necessarily mean high friction. A relatively strong relationship was found between friction and microtexture on the reference surfaces with grain sizes up to 125 µm. However, the relationships between texture and skid resistance on the aggregate and asphalt specimens turned out to be shallow for the investigated samples. For this reason, it was recommended to expand the number of investigated surfaces in further research to ensure sufficiently different levels of texture. Full article

Passenger cars differ in their levels of emitted noise and mileage, which can have a negative impact on the environment and humans. This was confirmed by the results of this study on the noise levels generated by passenger cars that have the same parameters, or are of one type. The loudest place in the tested vehicles turned out to be the combustion engine compartment, with the average noise level exceeding 90 dB and exhibiting a noticeable, significant increase alongside an increase in the mileage of the vehicles. This value of noise intensity is classified as dangerous for the human body. As a result of the conducted tests, it can be concluded that an engine cover is an important element in damping the sounds emitted by an internal combustion engine after the use of an aluminum heat shield to increase noise absorption. In the future, the environmental problem of noise emission from cars can be solved by encouraging the use of quieter, electric vehicles. Full article
