Impact of (flow rate/capacity) on average travel speed on urban highways characterized by signalized intersections

Estimation of traffic impact at signalized intersections around the proposed health campus in Etlik, Ankara Kazemi Afshar, Ali Asghar; Tüydeş Yaman, Hediye; Department of Civil Engineering (2015) A proposed integrated health campus with a total bed capacity of 3566 will be built in Etlik, Ankara, in an area surrounded by two urban corridors and served by six 3-legged and two 4-legged signalized intersections. For such a large medical facility with emergency services, it is important to assess its accessibility at these intersections by determining current and future levels of service (LOS), which is the objective of this study. According to Highway Capacity Manual, the estimation of LOS for a signal...
Use of bluetooth technology for traffic analyses in urban road networks Yücel, Şule; Tüydeş Yaman, Hediye; Department of Civil Engineering (2015) Bluetooth technology is a cheap and easy data collection method for traffic studies. It enables tracking of movements via detection of MAC addresses, unique to each Bluetooth device, without actually seeking any personal information. It is successfully used in traffic management in limited access corridors such as highway corridors. However, its potential in urban networks has to be evaluated to see the limitations, since it is more challenging in open networks, which is the main goal of this study. Within ...
Analysis of forging for three different alloy steels Civelekoğlu, Barış; Darendeliler, Haluk; Gökler, Mustafa İlhan; Department of Mechanical Engineering (2003) Forging is a manufacturing process which is preferred among the others in that, the final product shows more enhanced properties. The properties of the final product are directly related with the material used in the forging process. Main parameters such as forging temperature, number of stages, preform design, dimensions of the billet, etc. may be affected by the forging material. Alloys are one of the main areas of interest in the forging industry. The use of alloy steels may bring superior properties, es...
Detecting queue length on urban arterials using floating car data (FCD) Altıntaşı, Oruç; Tüydeş Yaman, Hediye; Tuncay, Kağan; Department of Civil Engineering (2018) Accurate estimation of queue lengths whether in the approach of a signalized intersection or near a bottleneck location along an uninterrupted urban arterial is essential for better traffic management. This requires reliable traffic data, which is traditionally obtained from loop detectors, video cameras, etc. More recently, Floating Car Data (FCD) is being increasingly used as an alternative traffic data source due to its lower cost and high coverage area. Commercially available FCD is obtained from GPS eq...
Analysis of comprehension of traffic signs: a pilot study in Ankara, Turkey Kırmızıoğlu, Erkut; Tüydeş Yaman, Hediye; Department of Civil Engineering (2010) Traffic signs, which are extremely important for traffic safety, aims to regulate traffic by providing information about the characteristics of road and road environment for drivers. The success of traffic signs mainly rely on the easy comprehensibility of its meaning in a short time. Further more, today’s global economies and transportation systems emphasize the need for more universial traffic signs which was the main motivation of two main treaties on traffic signs; Vienna Convetion in 1968 and European ...
