Abstract
Train service reliability is a key metro management objective and a major part of a successful operation. The occurrence of incidents in the network is likely to cause delays to the train service, perturbing the punctuality and regularity of the metro operation, and hence its service reliability. This suggests that one way to improve train service reliability is to reduce the occurrence of incidents in urban metro systems. This paper (which is presented in this seminar) uses statistical techniques to identify the main factors explaining the variation in the number of delay incidents across 42 metro lines (of 15 different metro systems) over the period 2005-2009. The results indicate that among the main factors explaining differences in incident performance across urban metro lines are the technology of the mode of train operation, the level of passenger demand, the service level operated during peak periods, and the practical capacity available. On the contrary, engineering, and usually fixed, metro factors such as the type of track support, the type of rail connection, the type of rolling stock wheel, do not have an effect on incident levels. The findings also suggest that metro-specific factors help explain the variation in incident performance, where such factors refer to differences in maintenance and management practices, operations management, health & safety procedures etc.

About the CTS Seminar Series
The CTS seminar series aims to facilitate discussion on current research topics in the transport field. Seminars are held jointly with our colleagues in the Centre for Transport Studies at University College London. They are usually held on Wednesday afternoons at Imperial College London or University College London. Seminars are free of charge and open to all interested parties. Booking is not required.
