Evaluation of alternative public transportation systems in Izmit urban transportation via axiomatic design method

Dunyada ve ulkemizde kent ici ulasimin buyuk bir bolumu toplu tasimacilikla gerceklestirilmektedir. Toplu tasima, araclara degil, insanlara ulasim kolayligi ve olanagi saglayan bir sistemdir. Bu nedenle kent ici ulasimin duzenlenmesinde toplu tasima sistemlerine oncelik vermek gerekmektedir. Bu calismada Izmit kent ici ulasimda trafik yogunlugunun azaltilmasina ve yolcu tasimaciliginin kolaylastirilmasina yonelik olarak hangi toplu tasima aracinin daha uygun oldugu belirlenmeye calisilmistir. Bunun icin oncelikle toplu tasima icin kullanilabilecek alternatifler belirlenmistir. Bu alternatifler, metro, metrobus, tramway, hafif rayli sistemler ve monoraydir. Devaminda toplu tasima konusunda karar vermeyi etkileyen degiskenler belirlenmistir. Bu degiskenler; maliyet, ulasim hatti ozellikleri, arac ozellikleri, cevreye duyarlilik ve musteri memnuniyetidir. Son olarak aksiyomlarla tasarim yontemi kullanilarak, en uygun toplu tasima sistemi konusunda oneride bulunulmustur. Yontemin uygulanmasi sonucunda Hafif Rayli Sistemler ve Metrobus, Izmit Toplu Tasima sistemi yapisi icin en uygun alternatifler olarak belirlenmistir. In the world and in our country, most of urban transportation is performed by public transportation. Public transportation is a system which provides transportation easiness and opportunity to people, not to vehicles. Therefore, giving priority to public transportation system is necessary in organizing urban transportation. In this study, in order to reduce traffic intensity and to facilitate passenger transportation in Izmit urban transportation, It is tried to determine appropriate public transportation system. For this, firstly, alternatives which could be used for public transportation were determined. These alternatives are metro, metrobus, tram, light rail system and monorail. Afterwards, the variables affecting decision making about public transportation were determined. These variables are cost, transportation line features, vehicle characteristics, sensitivity to environment and customer satisfaction. Lastly, most appropriate public transportation system is proposed by using the axiomatic design method. As a result, light trail system and metrobus are determined as the most appropriate alternatives for Izmit public transportation system.
