This thesis focuses on the contribution of the current user interface in the management the train traffic system on the Copenhagen S-Lane. The contribution is designed in a form of evaluation, looking at three aspects of the user interface. At ﬁrst, it evaluates the different characteristics and conﬁgurations of the user interface in terms of usability. Secondly, It is also looking at the different means offered by the user interface to enhance collaboration and communication in the control room. The ﬁnal aspect is the ability of the user interface to respond to critical situations on the S-Lane. The theoretical approach is built upon usability, ANT and CoP, including principles for risk management in relation to the management of critical situations. The evaluation led to the conclusion that the user interface contributes in the management of the train traffic through the detailed information it displays on the screen about the position and situations of trains, the situation on tracks and at the different stations. The information is collected and distributed consistently during the use of the interface. Such information helps performing tasks related to the management of the train traffic. The user interface contributes also by providing tools to perform actions efficiently, through the variety of interactive commands, and effectively, through the impact it has on the traffic system. The user interface also offers a margin of flexibility in the control and organization on the S-Lane traffic system.This thesis focuses on the contribution of the current user interface in the management the train traffic system on the Copenhagen S-Lane.
