“…Lately, streets have different types and purposes; expressways are for high-speed driving with minimal slopes and curves, principal arterial roads link major areas, minor arterial roads connect collectors or significant sources, collectors connect residential areas, and local roads divide households. They are surrounded by other roads [28][29][30]. In the late 1960s, urban economics transformed, with scholars adopting more analytical and rigorous approaches to studying urban economies.…”

Recent literature has highlighted the critical issue of urban land value and cost; properly assessing land use costs, particularly for residential and commercial purposes, is crucial in influencing urban development and investments. Therefore, the objective of this research is to create a model for land pricing that considers the urban street networks and hierarchy; by analyzing the spatial plan of the city using space syntax and evaluating the economic impact on land value, the study aims to identify the factors that influence land prices. Furthermore, the study intends to investigate the correlation between urban spatial networks, street hierarchy, and land price to create a predictive model for urban spatial land pricing. Ultimately, the study has successfully built a model for predicting the price of urban land. The case selected is evaluated and compared in three aspects of the analysis, including the urban axial assessments and urban street width, to find out their impacts on the real estate’s land price in the context of the land use distributions, which are predominantly residential and commercial types of uses. Depth map X8, SPSS, and QGIS 3.16 were used for the study evaluations and assessments. The study found that land prices are influenced by factors such as integration, connectivity, and street width. Commercial zones with good integration and wider roads tend to command higher prices, while narrow local roads generally have lower prices. This result can enhance future urban design regarding urban economy improvements and land costs.

“…Udio autonomnih vozila [4] Faza Vrijeme uvođenja Udio autonomnih vozila Prilagodba infrastrukture Očekuje se da će prva autonomna vozila najprije voziti po autocestama, a tek potom u urbanim sredinama i to u periodu između 2030. i 2050. godine [6]. Istraživanje [7] fokusirano na utvrđivanje naprednih funkcija autonomnih vozila pokazalo je da veliki uzdužni nagibi i kratke horizontalne krivine mogu uzrokovati pogreške u sustavu te da je na autocestama vožnja takvim vozilima najsigurnija s obzirom na njezine geometrijske karakteristike.…”

In the last few years, there has been an increasing amount of research dealing with the development of autonomous vehicles. The ability of autonomous vehicles to drive themselves, predict situations, communicate with surrounding vehicles and infrastructure, and interact with the environment in which they are located sets new requirements for designing road infrastructure. Gradual adaptation of the road infrastructure will largely depend on the level of development of autonomous vehicles and their share in the traffic flow. This paper presents the results of existing research related to the geometric design of highways adapted to the traffic of autonomous vehicles and provides guidelines for the implementation of further research. The main purpose of the research will be a detailed analysis of all project elements during the construction of new or reconstruction of existing highways, depending on the share of autonomous vehicles in traffic flow.

“…Na autocestama se, uslijed potrebe za ostvarenjem velikih brzina, primjenjuju veliki polumjeri horizontalnih krivina, blagi uzdužni nagibi nivelete, široki prometni trakovi i slično. Istraživanje [5] fokusirano na utvrđivanje naprednih funkcija autonomnih vozila pokazalo je da strmi uzdužni nagibi i kratke horizontalne krivine mogu uzrokovati pogreške u sustavu te da je na autocestama vožnja takvim vozilima najsigurnija, s obzirom na njezine geometrijske karakteristike. Uz navedeno, pokazalo se da vozilo ne prepoznaje uvijek horizontalnu signalizaciju pa sustav nije u mogućnosti pozicionirati vozilo u sredinu prometnog traka.…”

The introduction of new technologies, such as artificial intelligence in cars, raises the question of what the road infrastructure should be like in the future. The changes are expected to be significant, given that the human factor has influenced a number of design parameters. The ability of autonomous vehicles to drive themselves, anticipate situations, communicate with surrounding vehicles and infrastructure, and the environment in which they are located, places new demands on road infrastructure. Gradual changes in infrastructure will mostly depend on the speed of development of autonomous vehicles and their introduction into the transport system. Starting with intensive maintenance of roads and accompanying facilities, through separate corridors only for autonomous vehicles, while the goal is simplified and safe road infrastructure. The aim of this paper is to provide a review of the literature for the possible adaptation of road infrastructure intended for autonomous vehicles and to lay the foundation for further research in this area.
