TRAFFIC SAFETY PLANNING BASED ON NEAR ACCIDENT STUDIES

TRAFIKSAEKERHETSPLANERING GRUNDAD PAA STUDIER AV OLYCKSTILLBUD

A study of accidents, which often represent only those that have been reported to the police, does not provide sufficient information concerning contributory factors. Examination of potential accident situations, which it is estimated occur about 5000 times as often as accidents causing injury, is much more promising. It is well known that accidents to pedestrians on a non-regulated crossing at a four-way junction occur four times as often when a motorist is leaving the crossing as when he is approaching it. Since potential accidents, which according to definition occur when there would have been a collision between two road users within 1.5 seconds if one of them had not taken evasive action, take place about 40 times daily at a road junction, observations were made at 120 cross-roads in Stockholm and Malmoe. As a result of these studies, risk curves relating to conflicts at cross-roads have been drawn. Observations were also made of the effect of speed restrictions outside schools. Studies of potential accident situations showed that there was an improvement of 40% in safety. /TRRL/
