This paper focuses on the highway corridor Belgrade-Novi Sad, Serbia and the relationship between the highway and surrounding nature, as an integral part of the spatial entity which the highway belongs to. The paper emphasizes a high importance of studying the physical-geographical factors in the process of highway construction in order to achieve high level of traffic safety. Particular attention was directed to climate elements - the factors that are not so visible, but still may pose a great risk to road safety. Data were taken from CARPATCLIM database and their evaluation was confirmed by the data obtained from CHEK-LISTS. It was found that the climate elements have a strong influence, but it can be successfully controlled by vegetation. Landscape design of both sides of the highway may offer a possibility of mitigating the influence of climate elements, which was also pointed out in the paper.

Due to the high volume of traffic on European highways and the increased percentage of traffic accidents and fatalities, traffic safety is imperative in the planning and design of highways. While highway safety design construction standards have been extensively researched, insufficient attention has been given to the influence of the surrounding landscape on traffic safety and to drivers’ awareness about the danger of the same. Thus, the aim of the research was to assess drivers’ perceptions of various factors impacting highway traffic safety (climatic impacts from the surrounding landscape, landscape vegetation that follows the roadway, and animals) beyond specific engineering features (roadway surface, traffic signs, highway junction points). A survey of 138 drivers was conducted to assess driver awareness of traffic safety on the research section of a highway in Serbia. This highway is part of the Serbian highway that is a key connection within the European road network, forming an integral part of several major routes. The survey revealed that drivers, regardless of gender or experience, primarily associate traffic safety with well-built roads and good visibility during driving. While the impacts of climatic elements from the surrounding landscape were acknowledged, drivers do not strongly attribute any danger to traffic safety from these factors due to their lack of visibility. This is reflected in the notable number of traffic accidents, impacted by these factors, on the studied highway (e.g., 12% of the total number of accidents during 2022). Vegetation and animals did not play a significant role in the respondents’ answers, which should not be the case; however, their absence in the highway landscape and along the roadway led to a lack of observed quality by drivers. This underscores the need for the scientific community and policymakers to delve deeper into these issues with a broader perspective, and to elevate highway safety standards accordingly.

Due to intense highway congestion in Europe, increased percentage of highway accidents, as well as mortality rate, safety is an imperative in highway planning and design. Highway design safety standards have been researched extensively, but not enough attention has been paid to the surrounding environmental impacts, foremost climate elements. Therefore, this research attempts to understand the least researched climate element — the wind, and its impact on highway safety. The highway landscape falls under the category of the wind impacts that can cause significant problems for the drivers throughout the year. The values for wind direction, frequency and intensity were taken from the CARPATCLIM database. The evaluation of homogenized and harmonized set of data on a daily basis for a twenty-year period documented a variety of wind impacts on highway safety. It was found that the wind is constantly present throughout the year, with specific monthly oscillations. By using the ArcGis and the interpolation method, it has been clearly observed at which points the effect of intense winds was present the most. In order to understand the overall image of highway safety, fieldwork was conducted in various meteorological conditions. The checklists photo-documented and qualitatively described the observed extreme wind events (alone or combined with one more climate element). Based on everything described above, the image of the current situation was provided, and the proposal for control of the impact of wind using an adequate vegetation assembly (windbreaks) has been offered.
