Determinant remains the traveller's perception. The quality of service is connected with the terminals inside design, illumination, ventilation and provided service standards (promptly information, personnel attitude, waiting time). The service quality level in terminals for local, regional and inter-regional transport is determinant for making public transport more attractive. The paper focuses on aspects concerning the design and the capacity for ticketing and information systems in transport terminals. Different queue design possibilities are investigated under functionality, visibility equity and passengers spatial orientation. Analitical models for measuring performances of service are discussed in a critical manner. The non-stationarity of passengers arrival flows is outlined. Due to this, the classical analitical models provided by the q...

In actual operating conditions this minimum is difficult to obtain due to varying demands faced by ports. The solutions for the port facilities’development are based on the criterion that aims maximizing the social benefit obtained using the mathematical models of queuing theory. The paper aims to identify models for developing port facilities’ by which a rational dimensioning of installations subjected to time variable demands will be achieved (handling facilities at berth, covered / uncovered storage areas).Considering the multitude of mathematical models of the differentiated queuing theory according to the number of channels, distribution of arrival times and distribution of service time or the number of places in the waiting string / system, there is a problem of choosin...
