The benefits and costs to different stakeholders of the introduction of Performance Based Standards (PBS) in road freight transport were estimated from a number of case studies. The three factors said to cause traffic accidents are people, cars, and roads, with people causing almost all accidents. But preventive measures for locations, black spots, where accidents occur frequently are implemented focusing on road factors that appear to induce human factors. The normal way to identify locations of frequent traffic accidents and study traffic accident prevention measures is carried out based on traffic accident data. But considering that traffic accidents occur only rarely, to increase the safety of roads, it is necessary to not only introduce measures based on the results of accidents, but to also identify potentially dangerous locations where traffic accidents may occur and implement measures suited to the cause of the danger. But it is difficult to identify potentially dangerous locations based on accident data. This study was undertaken to prepare a Frightening Location Map based on a questionnaire survey to road users that was carried out to discover potentially dangerous locations and the causes of the potential danger at these locations. The causes of the dangers were identified by studying the road and traffic conditions at each dangerous location. The results showed many locations pointed out by multiple road users, revealing that potentially dangerous locations exist at places that can be specified to some degree. The results have also shown that it is possible to categorize the causes of danger as "road and traffic environment related conditions" and "human factors on the users' side". Road and traffic environment related causes include cases where trees obstruct visibility and cases of staggered intersections where drivers are confused about who has the right-of way. User side factors include drivers failing to see stop signs or red lights, or changing lanes without noticing following cars.
