Urban traffic networks suffer in numerous ways from traffic congestion. Some of these adverse effects are increased travel times
of cars, buses, bicycle users, pedestrians etc., with the addition of excessive greenhouse gas emissions. Transportation engineers
and policy makers try to improve the quality of urban transportation systems by developing projects to enhance the pedestrian
experience, reduce private car usage, reduce total time spent in the network through different control strategies, and diminish the
detrimental effects. In this context, this study takes Connected and Automated Vehicles (CAVs) and pedestrians into account at
signal-controlled intersections. A novel intersection signal control optimization methodology that incorporates pedestrian delays
and vehicular emissions from CAVs is presented. Non-dominated sorting genetic algorithm-II is utilized to solve the multiobjective
optimization problem. For the emission calculations, the MOVES3 emission model is utilized. The proposed framework is tested
on real-world case study. Simulation experiments showed major improvements in pedestrian delays and lower emissions.

The seismic events of magnitudes 7.7 and 7.6 that occurred in the Pazarcik and Elbistan districts of Kahramanmaras,
respectively, resulted in a disastrous aftermath characterized by a substantial loss of life, injuries
affecting a multitude of individuals, and extensive structural failures. The present investigation encompasses the
comprehensive assessments carried out by research team pertaining to industrial structures in the wake of these
catastrophic seismic events. These evaluations were centered on various categories of structures, including liquid
storage tanks, silos designed for the storage of grain-like materials, prefabricated reinforced concrete structures,
and low-rise steel industrial buildings. Wall buckling damage caused by the impulsive and convective effects of
the fluid has been detected in liquid storage tanks. Additionally, one of the tanks at the oil storage facility has
toppled on account of inadequate anchoring. Maize silos, displaying variations in design such as columnsupported
and ground-supported configurations, displayed noticeable structural damage at their base connections.
Additionally, the internal pressure generated on the silo walls during the seismic event led to structural
rupture, causing the discharge of grain-like agricultural commodities. Various types of damage were also
determined in precast structures. Inadequate connections between columns and beams, plastic hinges in columns,
and collapse of infill walls are examples of such damage. The significance of connections in low-rise steel
structures was also demonstrated in this earthquake. Furthermore, one contributing factor to structural damage
is the significant discrepancy in stiffness between different orientations of such structures. The study clarifies
both the manifestations of structural damages and their underlying causative factors related to strong ground
motion, while also delineating recommended precautionary measures.

Ülkemiz büyüyor, şehirlerimiz büyüyor. Cumhuriyetimizin ilk yılında, 1923’te, nüfusumuz 13.6 milyon idi ve bu nüfusun 1/3’ünden azı şehirlerde yaşıyordu. Oranlar bugün (2024) altüst olmuştur. Nüfusumuz 85 milyonu geçti ve TÜİK’e göre bunun 2/3’ü aşkın kısmı yoğun kent nüfusudur. Büyük şehir yaşamında kitlesellik hakimdir, bireyin özgür alanı dardır ve katlanmış sorunlar vardır. Bu makalede, şehirlerimizin büyüme iklim ve çevre bağlamındaki zorluklarının ekodost yaklaşımlarla aşılması ve sosyal belediyecilik konuları ele alınacaktır. Umulur ki, 31 Mart 2024 Yerel Seçimleri sonunda, hizmet aşkı ile dolu ve vizyonlu yerel yöneticiler başa gelir.

On February 6, 2023, two heavy earthquakes with moment magnitudes (MW) of 7.7 and 7.6 hit
the Kahramanmaras¸ region in southeast Türkiye. Aftershocks of moment magnitude of 6 occurred
consequently. These earthquakes affected more than 14 million people, and caused severe
damage to civil infrastructure including buildings, government offices, religious buildings, dams,
bridges, airports, and roads. After the earthquakes, a group of researchers visited the Hatay
province to assess the response of buildings. Hatay was one of the most heavily affected cities in
the region. The researchers gathered data on damaged reinforced concrete buildings, steel
structures, as well as masonry buildings. This paper focuses on discussing the findings and
analyzing the gathered data from reinforced concrete buildings and steel structures. A wide variety of issues that resulted in heavy damage or, in some cases, complete collapse of the buildings
are discussed. These problems include construction mistakes such as insufficient shear reinforcements, neglected corrosion, utilizing low-quality concrete, insufficient development length
in flexural reinforcements, and strong beam- weak column failure. In addition, various design
errors including excessive torsional response of buildings, rigidity difference in two orthogonal
directions of east–west and north–south of the building plan, pounding effect, short column
failure, and development of weak and soft stories are described using gathered pictorial data.
Finally, recommendations were made, and conclusions were drawn based on previous experimental and numerical studies of the seismic behavior of buildings as well as Turkish Building
Earthquake Code (TBEC- 2018) requirements.
