The rapid pace of urbanization all over the world and the growth of motorization have led to an unsustainable transport system. Karachi is a city suffering from the same phase of urbanization. This article aims to assess the sustainability of the city’s existing transportation system economically, socially, and environmentally and the degree of motorization. Data was collected through field surveys conducted in 2020 which include 15 hours of video recordings for traffic counts and the survey carried out at bus stops along two major arteries of Karachi. PM2.5 concentrations and the city’s vehicle profile were extracted from authorized websites. The data is analyzed graphically and statistically for various periods. The article sets out the level of sustainability and degree of motorisation of the transport system in Karachi and the travel behaviour of its user. It concludes that externalities and the lack of a planned system constitute obstacles to the provision of a sustainable transport system.

Teşekkür

The study would not have been possible without the vehicle count data and the behavioral analysis using the face to face survey technique in Karachi therefore, we would like to show our gratitude to the students of the Ned University of Engineering and Technology, Karachi for helping us gather the data to carry out our research. The article complies with national and international research and publication ethics. Ethics Committee approval was not required for Pakistan. This article was presented in the “IArcSAS” 1st International Architectural Science and Application Symposium on 27-29 October 2021 as an abstract. It was later expanded for this Journal.

Karaçi Kenti Ulaşım Sisteminin Sürdürülebilirlik Sütunlarının Analizi

Öz

Tüm dünyada kentleşmenin hız kesmeden ilerlemesi; motorizasyonun artmasıyla birlikte, sürdürülemez bir ulaşım sistemine yol açmaktadır. Karaçi aynı kentleşme aşamasını yaşamaktadır. Bu makalenin amacı, kentin mevcut ulaşım sisteminin sürdürülebilirlik düzeyini sosyal, ekonomik ve çevresel açıdan ve kentin motorizasyon seviyesini değerlendirmektir. Veriler, NED Üniversitesi (Karaçi) öğrencilerinin 2020 yılında yaptıkları saha araştırmalarından derlenmiştir. Saha araştırmaları, trafik sayımını belirlemek için yapılan 15 saatlik video çekimini ve Karaçi'nin iki ana arteri boyunca otobüs duraklarında gerçekleştirilen anketi içermektedir. PM2.5 yoğunlaşması ve kayıtlı araç sayısı resmi internet sitelerinden çıkarılmıştır. Veriler, değişen zaman dönemleriyle birlikte, grafiksel ve istatistiksel olarak analiz edilmiştir. Bu makalede; Karaçi'deki ulaşım sisteminin sürdürülebilirlik ve motorizasyon seviyeleri ile kullanıcıların seyahat davranışları ortaya konulmaktadır. Makale dışsallıkların varlığının ve planlı bir sistemin eksikliğinin sürdürülebilir bir ulaşım sisteminin sağlanmasında engel olduğu sonucuna varmaktadır.
