Proximal Safety indicators like TTC (Time to collision), PET (post encroachment time), DR (Deacceleration rate), etc are used to study driver behaviour at mixed traffic conditions at Unsignalized intersections. post encroachment time is the Time between the moment that the first road user leaves the path of the second and the moment that the second reaches the path of the first. Traffic capacity at unsignalized intersections are analyzed with “Conflict Technique” and capacity intersections are determined using volume, speed, time data .Surrogate safety measures( SSMs) are used to evaluate safety at urban areas , Safety aspect in terms for pedestrian-vehicular conflicts are also analyzed, Designing  of appropriate traffic signal at unsignalized intersections  are also done with the aid of Webster method. By the aid of 3D simulation models, capacity and driver safety at unsignalized intersection is improved.
