Traffic control with variable traffic equipment : a requirement analysis for the Swedish National Road Administration (English)
Abstract [en]

When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.

These proposals were prepared based on interviews with people from SNRA and their contractors as well as on comparisons with existing systems.

The focus of this report is the handling of system alarms and graphical user interface. By implementing the proposals in this report, the following will be achieved:

· More efficient alarmcontrol - the errors are discovered immediately or soon after they occur

· Clearer information regarding alarms - the traffic operator receives better information about the error

· Better control of the traffic equipment - the control will be easier and more flexible.
