Samenvatting
The accident study into the effect of traffic countermeasures in the demonstration- projects of Rijswijk and Eindhoven (executed during 1978- 1981) has resulted in a reduction of the number of injury accidents in residential zones as well as in traffic zones. After the introduction of the countermeasures during 1982- 1986 the number of accidents (related with vehicle kilometers) has decreased significantly more than in the control area.
