Although intersections constitute a little space on the urban road network, they are the areas where traffic crashes are concentrated. In this study, the relationship between traffic volume, intersection geometry, traffic control characteristics and vehicular fatal/injury traffic crashes (without pedestrians) were examined for 39 four-legged signalized intersections in the city center of Mersin during 2014 to 2016. For this purpose, Poisson regression and negative binomial (NB) regression models were used. The results showed that total number of approach lanes increases the intersection crashes. On the other hand, the increase in ratio of traffic volumes between primary and secondary intersection legs reduces the intersection crashes. The presence of median on primary intersection legs also reduces the number of crashes.
期刊介绍：
The scope of Teknik Dergi is naturally confined with the subjects falling in the area of civil engineering. However, the area of civil engineering has recently been significantly enlarged, even the definition of civil engineering has somewhat changed.
Half a century ago, engineering was simply defined as “the art of using and converting the natural resources for the benefit of the mankind”. Today, the same objective is expected to be realised (i) by complying with the desire and expectations of the people concerned and (ii) without wasting the resources and within the sustainability principles. This change has required an interaction between engineering and social and administrative sciences. Some subjects at the borderline between civil engineering and social and administrative sciences have consequently been included in the area of civil engineering.
Teknik Dergi defines its scope in line with this understanding. However, it requires the papers falling in the borderline to have a significant component of civil engineering.
