This paper presents the study carried out of accident analysis, black spot study and to identify the causal factors of accidents on NH-73A. The road accident trends and black spot ranking were established. The paper aims at identifying the accident trends on seven stretches on NH-73A according to year, month, time of the day, type of hitting vehicle, primary causes of accidents and black-spots. The results show that, the existing number of major access points without traffic lights, road marking, road furniture and proper road signs, rise in speed, increasing number of Annual Average Daily Traffic (AADT), heterogeneous nature of traffic, lack of proper road lighting conditions, poor shoulder design and maintenance, bad road conditions and design are the potential contributors of incremental accident rates on the given roadway. The measures for improvement based on identified causes include construction of road features such as paved shoulders, pedestrian crossing, strict implementation of speed limits and traffic lights, proper road markings and signs, speed breakers and traffic lights to be provided.
