Individual and neighborhood determinants of perceptions of bus and train safety in Chicago, Illinois - Application of hierarchical linear modeling

Individuals decide to use public transit in part on the basis of their perception of transit safety, which is determined by various individual and environmental factors. This paper adopts a multilevel approach to analyze how perceptions of bus and train safety in Chicago, Illinois, vary as a function of person-level characteristics-gender, age, ethnicity, income, and frequency of transit ridership-and neighborhood-level characteristics-perceived neighborhood disorder, population density, and level of poverty. Hierarchical linear modeling is applied to a unique data set that combines data from three different sources: Chicago Transit Authority data on individual-level perceptions of transit safety and individual demographics, Chicago Alternative Policing Strategy data on perceptions of neighborhood disorder at the zip code level, and U.S. Census zip code-level demographic data. Findings show that the individual- and zip code-level effects differ depending on whether the estimation predicts bus or train safety perceptions. Additionally, while higher-income individuals and African Americans report lower levels of perceived bus safety, there is an additional zip code effect: low-density and high-poverty areas and neighborhoods with high levels of disorder have significantly lower levels of perceived bus safety. Management and policy implications of the study for both the transit agency and the community in which service is being offered are discussed.

Urbanity in the Open Spaces in Developing Nodes along Main Arteries: Söğütözü Node on Dumlupınar Road in Ankara
Aral, Hacer Ela; Uysal Bilge, Fulay; Doğu Demirbaş, Güler Ufuk (Middle East Technical University Faculty of Architecture, 2022-6)
The effects of the main transportation arteries on the urban sprawl and the formation of new public spaces is an important topic of discussion today. Considering the urban roads, major arteries trigger fast development and the formation of a significant amount of urban open space together with buildings. Vehicular roads are the main elements that bring out urbanity and centrality by providing a combination of circulation at different speeds and making possible the interaction of users from local and remote ...
Transit oriented design and urban design: eskişehir case – tram stop oriented
Bahçelioğlu, İrem; Yetişkul Şenbil, Emine; Urban Design in City and Regional Planning Department (2017)
Sustainable and public transportation plays a vital role in the cities to eliminate the disadvantages of urban sprawl. Transit oriented development (TOD) is one of the tools which is used to solve this problem. However, the efforts of TOD itself are not enough in order to increase the public transportation demand. TOD reaches significance when it is combined with the urban design since urban design defines both physical and personal factors in the point of creating effective TOD. For this reason, design fac...
Kentsel Kavşaklardaki Elektronik Denetim Sistemlerinin Trafik Kazalarına Etkisi: Ankara Örneği
Kaygısız, Ömür; Sümer, Nebi (Middle East Technical University, Faculty of Architecture, 2017-11-20)
Kentsel kavşaklar, özellikle metropollerde hem ulaşım hareketliliği hem de trafik güvenliği bakımından en kritik mekânlardan birisidir. Son yıllarda yaygın olarak kavşaklarda kurulan Elektronik Denetim Sistemleri’nin (EDS) trafik güvenliğine katkıda bulunması beklenmektedir. Bu çalışmanın amacı, kentsel ışıklı kavşaklara kurulan EDS’nin genel olarak trafik güvenliği ve özel olarak da taşıt ve yaya kazası sıklığı üzerindeki etkisini araştırmaktır. Çalışmada, Ankara ilinde EDS kurulumu yapılan 21 kavşaktaki ö...
Planning and management of bike sharing systems for sustainable urban transport : Konya, Kayseri and İstanbul cases
Erçetin, Cihan; Babalık, Ela; Department of Urban Policy Planning and Local Governments (2014)
Considering the problems of traffic congestion, energy dependency and air pollution depending on excessive use of private car, different transport alternatives to ensure sustainable urban transportation have come into question. Particularly in some European countries, bicycle use, which does not create any pollution and uses resources and road space at a minimum, has appeared as a sustainable alternative for urban transportation and besides, recently bike-sharing systems have contributed to this process pos...
Low-energy alinite cement production by using soda waste sludge
Uçal, Gültekin Ozan; Tokyay, Mustafa; Department of Civil Engineering (2016)
Increased environmental awareness and the concept of sustainable development have impacts on cement industry as on many other fields. Alinite cement which was developed in the 1970s may be an alternative inorganic, low energy binding material. In this study, synthesis and optimization of the properties of alinite cement was carried out by using soda waste sludge as a raw material. Soda waste sludge was mixed with limestone, clay, and iron ore in different proportions. All mixes were burned at 1050oC or 1150...
