The software suite ANNA+ is a web-based, user-friendly quality analysis system for traffic signal controls. It makes it possible to perform regular and comprehensive system analysis that goes beyond specific, single-target checks.


Complex traffic signal controls must meet the high expectations and standards of both road users and system operators. To prove that these standards are being met and to ensure that the control is working properly, it is necessary to perform regular and thorough checks of the control. Because of the enormous amount of data contained in these controls, until now it has only been possible to perform specific, targeted tests. ANNA+, the software suite we developed to address this limitation, allows you to manage large data volumes and perform broad, system-wide analysis.
