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 signa
lized 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.
