Investigation of Direction based Microscopic Traffic Stream Parameters for Ankara-Polatlı State Highway-Polatlı Direction

Ankara is the capital and one of the most populous cities of the Republic of Turkey.The Ankara-Polatl state road connects Ankara with western and southern Turkey and is one of the most important state roads in Turkey.Therefore, it is a critical highway section, not only for Ankara but also for Turkey.Thus, the contribution of improvements to this highway is significant for Turkey.Traffic data was recorded by the traffic cameras on the Ankara-Polatl State Highway.This data includes the time and velocity of vehicle crossings in the Polatl direction.By performing vehicle flow analyses for the Polatl direction on this state road, which operates as a 2x3 divided road, the traffic flow characteristics and the status of traffic flow are revealed.The outcomes can be evaluated for management and future transportation operations.
