Fractal analyzes of age-friendly transportation system: A comparison of the İstanbul Kadikoy and Besiktas

Abstract

There has been a notable rise in the older adult population and urbanization on a global scale. Urban design has a virtual role in meeting the demands of the old population and promoting their social engagement and independence. The WHO (World Health Organization) has released an all-encompassing manual on age-friendly cities, covering eight categories. Transportation is considered one of the primary concerns highlighted by the WHO. The availability of accessible and dependable transportation choices is significant in ensuring the maintenance of independence and participation in a wide array of social and recreational activities for older individuals. Furthermore, implementing a well-designed transportation infrastructure in urban areas that prioritizes the creation of age-friendly surroundings provides convenient access to various facilities for the older adult population. The objective of this study is to provide a comprehensive analysis of urban transportation networks by evaluating their intricacy and scope via the use of fractal geometry. This research aims to investigate, evaluate, and compare the age-friendliness of urban transportation networks by assessing the complexity and extent of the transportation system using fractal geometry in two particular areas of Istanbul, namely Beşiktaş and Kadıköy. The topic under consideration needs to be more dependable quantitative investigations. This lack of quantitative investigation hinders our understanding of the efficiency and effectiveness of transportation systems in urban areas. Therefore, conducting a comprehensive analysis using fractal geometry can fill this research gap and provide valuable insights into the intricacies of urban transportation. Additionally, such quantitative investigations can inform policymakers and urban planners to make informed decisions to improve the transportation infrastructure for all age groups, including older people. A box-counting study was performed on the Besiktas and Kadikoy transportation networks in Istanbul, which are included in the age-friendly community, to evaluate their age-friendliness and efficiency. The study's results suggest that the public transportation system in Kadikoy exhibits a higher degree of intricacy and resemblance to itself than the system in Besiktas. The public transportation system in Kadikoy demonstrates a higher fractal dimension, suggesting a heightened level of connectivity and efficiency compared to the Besiktas system. This indicates that the residents of Kadikoy are expected to experience advantages from improved transportation infrastructure, leading to reduced travel times and improved connectivity across different parts of the district. In addition, the higher fractal dimension of the public transportation system in Kadikoy may also indicate a more significant number of alternative routes and options for commuters, further enhancing their ability to navigate the district efficiently. The enhanced connection and improved efficiency can foster a more sustainable mode of travel in Kadikoy by promoting a transition towards public transportation and diminishing dependence on private automobiles. Additionally, the higher fractal dimension in Kadikoy implies a more robust and interconnected network, allowing for easier access to various amenities and services within the district. This could boost the well-being of inhabitants. The results of this research may be used in public transportation to evaluate its effectiveness by identifying its strengths and weaknesses. Therefore, this strategy seeks to aid policymakers and planners in thoroughly comprehending the current transportation system's benefits and drawbacks.
