This study re-examines Izmir’s planning experience during the early Republican period(1923–1965) through the relationship between planning decisions and urbanmorphology, with particular focus on the 1955 Kemal Ahmet Aru Plan. The first partcomparatively discusses the 1925 Danger–Prost approach, the 1949 Le Corbusierproposal, and the 1955 master plan that emerged from the 1952 competition process interms of transport structure, industry–housing relations, development directions, andimplementation capacity. The second part compares three road-network states withinthe Aru Plan boundary: the existing pattern of the 1950s, the 1955 plan proposal, andthe early realized pattern of the 1970s. For this purpose, the road system was digitized,fractal dimension was calculated through box-counting, and Local Connected FractalDimension (LCFD) maps were produced. The findings indicate that the Aru Plan did notreject the existing urban pattern entirely, but rather proposed a more hierarchical andcorridor-based network structure. By 1970, this logic had produced a higher level ofspatial complexity through the interaction between planned guidance and actual urbangrowth dynamics. Stronger fractal intensity is concentrated along the historical core,port, industrial areas, and major development corridors, while peripheral zones displaylower levels of integration and a more fragmented spatial pattern. The study aims tobuild a methodological bridge between planning history and urban morphology byevaluating Izmir’s planning experience not only through institutional and historicalnarratives but also through the quantitative analysis of road-network morphology. Sincethe analysis is limited to the road-network representation, future studies shouldintegrate additional morphological components such as parcels, building patterns, andland use.
