استخدام تقنية التعارضات المرورية TCT لتقييم التقاطعات الخطرة في مدينة دمشق

Abstract EN

Traffic Conflict Technique TCT has a long history in traffic safety researches.

Traffic accidents are now well known to generate a serious problem that exhausts enormous resources of the national economy either directly or indirectly.

Because signalized intersections are potential black spot locations that may cause too many accident this research uses the traffic conflict techniques for analyzing accidents at signalized intersections.

In this research, TCT was used at four-leg signalized intersections in Damascus to evaluate safety at these intersections.

The relationship between conflicts and accidents was estimated and the results indicated that the conflicts and the accidents are related to each other by a linear regression.

Results also showed that the correlation was unclear between conflicts and entry volumes at the intersections.

Additionally, priority ranking of these intersections was developed based on risk index that depends on injury level.
