**8.1 First main criterion**

In this criterion aiming to measure the urban design quality of Turkish cities in terms of the physical design, there are five sub-criteria. Constituting the main principles of the physical design in general, the highest score among the five criteria was 0.35, whereas the lowest one was 0.15. Since it has a score of 0.35, "diversity" is the criterion with the highest score, but it is much lower than the intermediate level (0.50). Moreover, the mean score of these five criteria was found to be 0.21. From this aspect, the score of the main criteria is 0.19. Given these values, it can be understood that urban design quality is not at a good level in Turkey. All the scores were found to be below 0.35. There are many problems to solve before Turkish cities can come to the forefront with their planned development. It is an inevitable necessity to reconsider the integrity of planning and design in both planning and designing processes. It is understood from these results that, without considering the identities and characters of the cities, they were either damaged or neglected and not included in the planning and design processes. Rather than emphasizing or enhancing the diversity, an inclination towards stereotyping and monotony has been exhibited. Rather than making the cities more readable and defined, the complexity and irregularity have become the dominant approach. The physical and functional continuity has been destructed by the point regulations. There are many undefined areas. The effects of guidance, coverage, and closeness have decreased. Rather than flexible regulations meeting the current necessities, strict and oldschool implementations have become prominent.
