International Tunnel Control System - Introduction and experiences from realization

International Tunnel Control Central (ITCC) was developed by international group of engineers inside Siemens Intelligent Traffic System Division. Engineers were originally from Czech Republic (ETODO dopravni systemy s.r.o.), Germany, Austria, Switzerland and Nederland. The main goal of the system is to unify tunnel control system software approaches used in each involved country to improve efficiency and reliability of new system together with increasing of total tunnel safety. The structure of ITCC system and system features is demonstrated including examples of software control modules. Special consideration is focused on traffic, mechanical and electrical modules. The experiences with ITCC on real project are presented. The approach to design and realization of complex tunnel control system on Sitina tunnel in Slovak Republic is discussed as the first example and the control systems for Turkish highway tunnels Bolaman-Persembe and Giresun-Espiye as the second example.
