Towards a classification of road incidents acquired from public fleets of vehicles
Abstract
The accident number has decreased considerably since 2003 in most of the countries. So, it becomes difficult from only accidents data to obtain ‘black spot’. Consequently, it can be interesting to work on incidents instead of accidents in order to prevent them. In order to acquire incidents, about 50 EDR (Event data recorded) have been implemented in different public fleets of company vehicles. After 6 months of acquisition, approximatively 700 events have been recorded. This paper illustrates the different types of events:’simple’ events in urban, interurban and highway area, lateral and longitudinal ‘incidents’ and finally accidents. It is highlighted in particular that the event acquisition can be used to improve road infrastructure or to improve knowledge in the accident/incident mechanisms analysis. Finally, it is proposed a classification of these events in ‘safety relevant’ or not in order to set up methods which allow automatic processing during the data exploitation.
