The identification of incidental learning as a cause of human error by exploring big data within railway safety

Accidents at work come at a major cost including fatalities, disability and economic burden. The ideas around accident causation have changed over time from describing accidents as ‘acts of gods’ and as the fault of individual employees, to accidents being the result of an interaction between organizational, technical and human factors. Included...

What employees do today because of their experience yesterday: Previous exposure to yellow:number aspects as a cause for SPAD incidents

When a train passes a red aspect, this is called a Signal Passed at Danger event or SPAD. Sometimes it is easy to identify the SPAD cause but in other cases it is unclear why the incident occurred, especially if the system operated as usual and the train driver was trained and experienced just like his or her colleagues. In previous research,...

What employees do today because of their experience yesterday: How incidental learning influences train driver behavior and safety margins (a big data analysis)

Employee behavior plays an important role in the occurrence and prevention of incidents, affecting safety margins. In this study, we examine the potential impact of incidental learning on human behavior in the presence of variation in task design. Incidental learning is the day-to-day on-the-job learning that occurs unintentionally. This...

Design of a multi-functional vehicle which supports passenger and cargo transport

Online shops are responsible for a significant increase in the total volume of parcels which have to be transported. Due to the increase in volume there are more vehicles required to meet this enormous demand. This has a negative impact on the traffic flow on the infrastructure. A possible solution can be found in ride-sharing, as sharing...

How cognitive biases influence the data verification of safety indicators: A case study in rail

The field of safety and incident prevention is becoming more and more data based. Data can help support decision making for a more productive and safer work environment, but only if the data can be, is and should be trusted. Especially with the advance of more data collection of varying quality, checking and judging the data is an...

Full system response Thomassen tunnel under impact load using LS-DYNA (concept version 3)

In the Delft Cluster work package “Bijzondere Belastingen” (CT01.21) the consequences of a BLEVE and a reduced BLEVE are considered. These phenomena have a low probability of occurrence, but might have immense consequences. Therefore, a deterministic consideration seems not possible. The results of the work package must facilitate the...

Bijzondere belastingen in tunnels: Eindrapport

Verkeerstunnels en overkapte wegen (landtunnels) komen de milieukundige en stedenbouwkundige inpassing ten goede en maken meervoudig ruimtegebruik in de stad mogelijk. Het aantal tunnels en overkappingen groeit dan ook. Dit maakt het vervoer van explosiegevaarlijke stoffen en onder hoge druk vervoerde gassen steeds moeilijker, want tankwagens...
