Abstract

To be able to manage traffic proactively, transport network managers should be able to identify different risk factors on the transport network and thus be able to predict the occurrence and likely consequences of incidents. The significance of different traffic and environmental conditions in increasing accident risk was studied by looking at registered accidents that happened on Ring road I of the Helsinki metropolitan area. It was found that the spatial accident distribution was far from uniform and showed some strong peaks at different locations - useful information in considering means for preventing accidents. Temporally, the annual distribution of accidents also showed some clear patterns (e.g. peaks in February and September-October). In addition, the rush hours between 3 p.m. and 5 p.m. had a higher risk of accidents than the morning rush hours. Surprisingly, the traffic density itself did not seem to affect the accident risk. Snowfall, ice and snow on the road, and poor visibility were also identified as risk factors.
