Abstract
In railway and metrorail systems the present trend is to use Integrated Traffic Management and Control Systems able to improve the profitability and quality of rail services. Considering the complexity of these systems, which have to include and manage information from a multitude of different main subsystems (centralised traffic control systems, passenger information system, control and supervision of traction power installation systems, management information systems, etc.) several methods have been introduced in order to develop the system architecture in accordance with high quality and reliability targets. As far as the software modules are concerned, reliability assessment methods are in progress, oriented both to a qualitative and/or a quantitative analysis. The authors consider the applicability of these methods in the proposed transport system and critically analyse the possible options for a commercial software, which can be suitably used in a general integrated traffic management and control system.
