Abstract
In this study, control structure related to the safety of the point automation system, which has a critical significance on tram lines, was designed through Timed-Arc Petri Nets by taking CENELEC 50128 standard as reference. CENELEC 50128 strongly recommends the utilization of Timed-Arc Petri Nets during system modeling (Table A.17) and the utilization of formal proof methods during the verification and test phases of command and control structure developed (Table A.5). The verification was performed through CTL (Computational Tree Logic), which is one of the formal proof methods. Timed-Arc Petri Nets model has been used for the first time in this area through this study. Within this context, the structure was developed by taking the point automation system at the Bastabya Station on T4 Topkapi-Habibler line, operated by Istanbul Ulaşim as the reference. Moreover, safety requirements for the automation of the points were identified and denoted mathematically while their safety functions were designed.
