Samenvatting

Failure to adapt vehicle speed to the prevailing road, traffic and visibility conditions is a significant cause of road accidents. The legal speed limits merely indicate the speeds that may not be exceeded under any conditions. One may only drive at the limit under ideal conditions. Speed limits give no indication of how fast one may drive when conditions are bad. The Swiss Council for Accident Prevention bfu approached the Road Safety Fund (FVS) with a request for assistance in financing a survey on the subject of `Speed discipline and risks associated with various road conditions and different times of day and week. The purposes of the survey are: (1) to analyse the accident cause `speed' from statistical data in respect of various situations, such as road conditions, time of day and weekday, (2) to ascertain the speed driven in the above situations, (3) to highlight the various risk factors in relationship to situation and speed, (4) to draw conclusions from the results of the accident analysis, the speed measurements and the risk assessment for application in everyday accident prevention work, and (5) to recommend practical measures to reduce the share of the accident cause `speed' in the overall accident statistics. The risk assessment and the speed measurements show that driving speeds in poor visibility and difficult weather conditions on motorways and out-of-town roads are too high. The majority of car drivers are clearly not in a position to: a) estimate their own speed, b) adapt their speed to suit the prevailing conditions, and c) recognize the high risks associated with driving at night in the rain. These conclusions apply especially to young men. Measures to reduce the risks at night when it is raining should be taken at the driver training stage, through information and by means of legislation. Later, one should also consider the application of new safety technologies, as necessary. It is recommended that a) More emphasis should be placed in both theoretical and practical driver training sessions on explaining physical laws and spelling out the various risks involved, b) By using the full range of information media, road users should be offered regular advice about important aspects of behaviour on the roads. It should be pointed out who is exposed to what risks under which circumstances, as well as what speeds are appropriate for which conditions, and c) Since the majority of drivers experience difficulty in choosing the right speed at which to drive, consideration should be given to the introduction of separate recommended speeds for darkness and for wet weather. These recommended speeds should be considerably lower than those applying to daylight and normal conditions. There should be increased police control activity specifically aimed at ensuring that, in high-risk conditions (at night, in the rain), at least the legal speed limits are adhered to. These are currently being exceeded, in some cases by a massive amount. (A)
