Samenvatting
Passengers in public transport indicate that alcohol and drug addicts give the most nuisance for them. Railway and metro stations have become their residence, they attack the passengers or steal their belongings. The approach of attack of the alcohol and drug scene is not for the public transport, but public transport can take their own measures to prevent the criminality and the nuisance by the addicts. Some of these measures are a limited access to the stations by a better control or by the duty to have an access ticket.
