2-Analysis of target situation Use additional prompting questions to identify more details about a specific problem: location, behaviour, existing measures.

Once the problem has been defined globally, the next step should include the detailed understanding of a target situation where measures are considered for implementation. Information can be collected from different data sources such as: behaviour reports, accident / suicide investigation report (if available), specific incident reports, or CCTV   footage.

The characteristics of the specific location should be considered: the environment, spatial configuration, history of the site, pre-existing measures and specific constraints. At this stage you can use relevant characteristics from a list to obtain more data (based on the categories within e.g., location – station, crossing, etc.), review of existing measures in targeted locations, conduct field visits, check the safety record, brainstorm with RU / IM experts, etc. Try to figure out what is needed at that specific site to eliminate / diminish the target incident.

Actions Questions to be answered Issues to be considered
Definition of target location What is the exact location in question? -* track address / sector -* particular station -* boundaries of targeted site (map) -* any particular configuration of the location
Problem behaviour What do the statistics of suicides and attempted suicides tell about the problem? -* distribution in time -* exact locations -* information of details
What do the statistics of trespassing accidents tell about the problem? -* distribution in time -* exact locations -* by severity -* other details
What is the frequency of trespassing? -* counts of trespassing needed, if information is not available
Is it possible to identify the routes used by trespassers? -* point of entry and point of exit -* trespasser flows per route
What are the motives of problem behaviour? -* observations -* interviews of trespassers -* interviews of local residents -* questionnaire to local residents
What are the targeted people? -* children playing -* children going to school -* youngsters loitering -* vandalism -* adult commuters -* people during their free time activities (e.g. walking their dog, taking photographs) -* people going to / coming from sportive activities on stadiums -* people going shopping, coming home from a bar, etc. -* people with mental problems -* people with suicide intent prone to choose the railways as a means
Existing measures What are the details of existing measures? -* lack of present safety measures -* for each measure separately -* what, where, when implemented -* current status? -* need of maintenance?
What is the estimated effectiveness of existing measures? -* for each measure separately -* does it work as intended? -* if not, why? -* if studies do not exist, provide expert estimate
Definition of the objectives of new measures What are the targeted incidents? -* suicides -* suicide attempts -* trespassing accidents -* trespassing behaviour
What is the targeted behaviour? -* exactly where within the target location the targeted behaviour occurs -* is it focused in certain time periods (e.g. summer or night) -* does the targeted behaviour have some specific features (e.g. loitering on platforms, concerns especially teenagers etc.)
