Comprehensibility of traffic signs among urban drivers in Turkey

Kirmizioglu, Erkut
Tüydeş Yaman, Hediye
Traffic signs are commonly used traffic safety tools, mainly developed to provide crucial information in a short time to support safe drive; but the success depends on their comprehensibility by the drivers. Also, a sudden change in the traditionally used and accepted signs can cause significant safety problem, as in the case of cancellation of red oblique bars in 2004 as a part of the European Union Harmonization Process of Turkey.


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 ...
Characteristics of cloverleaf interchange in Turkey
Yalçın, Esra Gözde; Tüydeş Yaman, Hediye; Department of Civil Engineering (2018)
Level of Service (LOS) is a qualitative key attribute for monitoring traffic performance of road infrastructure. As interchanges are major but rather limited designs in road networks, providing uninterrupted flow with high capacities, there is a no LOS concept developed for them. However, data collection capability via Bluetooth (BT) readers located at interchange approaches make it possible to collect continuous speed and travel time data for all possible movements, which can lead to a measure for LOS for ...
Speed-Related Traffic Accident Analysis Using Gis-Based Dbscan And Nnh Clustering
Topcuoglu, B.; MEMİŞOĞLU BAYKAL, TUĞBA; Tüydeş Yaman, Hediye (2022-8-05)
To ensure road safety and reduce traffic accidents, it is essential to determine geographical locations where traffic accidents occur the most. Spatial clustering methods of hot spots are used very effectively to detect such risky areas and take precautions to minimize or even avoid fatal or injury accidents. This study aims to determine speed-related hot spots in the pilot Mersin Region, which includes seven cities in the central-southern part of Turkey. Two different hot spot clustering methods, the Neare...
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 ...
Influence of traffic enforcement on the attitudes and behavior of drivers
Stanojevic, Predrag; Jovanovic, Dragan; Lajunen, Timo (2013-03-28)
Traditionally, traffic enforcement has been an important means of improving traffic safety. Many studies have provided evidence of connections between the level of police enforcement and both driving behavior and the number of traffic accidents. In Northern Kosovo, there has been little, if any, traffic enforcement during the last 13 years. This situation has created a very rare research opportunity - it is now possible to directly study the influence of traffic enforcement on the attitudes and behavior of ...
