Kentsel yolculuk amaçlarýnýn farklýlaþmasýnýn yaný sýra, yolculuk taleplerinde yaþanan artýþ, kentlerin büyüklüðüne baðlý olarak taþýt hareketliliðinin daha uzun mesafeler arasýnda yapýlmasýný gerekli kýlmýþtýr. Farklý kent büyüklükleri, hýzlý ulaþýmýn amaçlandýðý günümüzde, özel otomobil kullanýmý odaklý önlemlerin alýnmasýna neden olarak kentsel ulaþým aðýný þekillendirmiþtir. Her kentlinin farklý ulaþým talepleri, kentsel ulaþým sisteminde alternatif ulaþým türlerinin hizmete girmesini gerektirmiþtir. Böylesi bir durumda, büyükþehir ya da küçük ve orta ölçekli her kentin ulaþtýrma altyapýsýnýn ve kentin ihtiyaçlarýnýn göz önünde bulundurulduðu bir model üretilmesi ihtiyacý ortaya çýkmýþtýr. Bu model vasýtasýyla, kentin ulaþým yapýsý çözümlenir, kentlinin deðiþen yolculuk taleplerine göre kurgulanacak ulaþým sistemi ve çeþitli ulaþým türleri arasýnda yolculuk yoðunluðuna göre nasýl seçim yapýlacaðýna iliþkin öngörülerde bulunulur. Bu çalýþma kapsamýnda, temelde Varlýk-Ýliþki modeli olarak adlandýrýlan bir kavramsal model çerçevesi oluþturulmuþtur. Bu kavramsal model, kentsel ulaþým sistemlerinin ve alternatif ulaþým türlerinin belirlenmesinde, teorik altyapýyý pratik uygulamaya dönüþtüren kuramsal bir temel oluþturmayý amaçlamýþtýr. Bu çalýþmada, Türkiye’de farklý nüfus büyüklüðüne sahip farklý boyutlarda kentler için alternatif bir ulaþým türü olan P+D sistemlerinin, kent merkezi çeperi ve kent bütününde konumlandýrýlmasýnda kurgulanan Varlýk-Ýliþki modelinin üretildiði bir kavramsal model önerisi geliþtirilmiþtir.

Different urban sizes have shaped the urban transportation network by taking measures focused on the use of private cars today, where rapid transportation is aimed. Different travel demands of each inhabitant required alternative modes of transportation to be put into service in the urban transportation system. In such a situation, the need to produce a model that takes into account the transportation infrastructure of the metropolitan or small and medium-sized city and the needs of the city has emerged. With this model, the transportation structure of the city is analyzed and forecasts are made regarding the transportation system to be designed according to the multiple journey demands of the city and how to choose among the various transportation types according to the travel density. In this study, a conceptual model framework, basically called the Entity-Relationship Model, has been created. This conceptual model aims to create a theoretical basis that transforms the theoretical infrastructure into practical application in determining urban transportation systems and alternative modes of transportation. In this study, for cities of different sizes with different population sizes in Turkey an alternative transportation modes with a P + D systems, town walls and the city a conceptual model is proposed for the production of remixed Entity-Relationship model in the positioning of the whole it has been developed.
