ANNA+

The Advanced Quality Analysis System

ANNA+ is the Web-based software system for analyzing the quality of and evaluating signal controls. Based on the open process data interface "OCIT-PD", data is transferred via a central traffic computer to ANNA+.

The interactive analysis includes private transport control logs (green and red times, amount of green time actually used, offset times between signal groups, etc.), the display of signal timing plans and the presentation of coordination quality in time distance diagrams. These diagrams clearly display all irregularities in synchronization and switching.

Public transport analysis includes the evaluation of priority systems (e.g. transponder and detection systems). In addition to extensive tables containing data on lines, directions and routes, a comparison of actual and target values illustrates timetable compliance, travel time between detection points etc.
