A Case Study on the Effectiveness of Speed Enforcement on Roadways in Turkey

Bu calisma Turkiye karayollarindaki hiz denetim yontemlerinin etkinligini arastirmaktadir. Polisin ve sabit radar uygulamalarinin ne kadar uzakliga kadar etkili oldugunu gorebilmek icin 452 surucu uzerinde bir arastirma gelistirilerek uygulanmistir. Bulgular, hem polisin hem de sabit radar uygulamalarinin ortalama etkisinin 1 km'den oteye gecmedigini ortaya koymustur. Sabit radar uygulamalari ile polisin radar uygulamalarinin suruculer uzerindeki etkileri arasinda herhangi anlamli bir fark gorulmemistir. Polis tarafindan uygulanan hiz cezalarinin surucu davranislari uzerinde genellikle etkisinin olmadigi anlasilmistir. Bu bulgular isiginda, ortalama hiz kontrolu gibi yeni metotlarla birlikte sabit ve hareketli tam zamanli acik ve gizli kameralari zaman zaman polis refakatinde birlikte uygulayacak entegre bir sistemin olmamasi halinde, Turkiye'deki karayollarinda hiz denetimlerinin basari sansinin son derece dusuk olacagi sonucuna ulasilmistir.

In order to find out the distance halo effects of physical policing and fixed speed cameras, a research was developed and conducted on 452 drivers. The data was revealed that the average distance halo effects of both physical policing and speed cameras were not more than 1 km. Any significant differences were not detected between the speed behaviors of drivers those who have been enforced by physical policing with radars and that of those enforced by overt fix speed cameras. The tickets applied by the police were found mostly to be ineffective on the speed behaviors of drivers. In light of these findings it is concluded that unless a mix system including full-time operating overt and covert cameras both fix and mobile accompanying by random physical policing and the new methods such as average speed control, the success of speed management on roadways in Turkey is hardly possible.
