Software IJtramtunnel (tunnel for streetcars)

Description:
The Piet Hein streetcar tunnel is equipped with a lot of safety and security systems. These exist among others of many detection systems, controlled escape routes, an extensive camera system, intercoms in the tunnel, and many technical systems like intelligent lighting and emergency power supplies. These systems are monitored by the `traffic controller street car' from the traffic control centre of public transport control centre of Amsterdam. For this tunnel vhp ergonomics developed:

1. working method and procedures when incidents occur
First a scenario research was carried out in which four possible incidents in the tunnel were written out in detail, the so-called usecases. In the scenarios it is elaborated how the traffic controller must act during the incidents and which information he needs.

2. the workstation
For the control of the tunnel, the traffic controller has available: two displays, numerous communication devices and a monitor wall with ten camera displays.

3. the GUI for the tunnel software
The scenarios are worked out in detail up to a functional list of requirements for the GUI including designs for the different interfaces that are presented on the screen. The soft-ware is made ‘intelligent’ where possible. All scenarios are worked out to the detail of the information that is needed and the control that is possible.
The GUI is worked out tot a technical design by the supplier of the tunnel installations.

vhp maintained a close contact with the programmer during the realisation phase. In this way it was guaranteed that the aimed functionalities would be implemented as designed.
