© 2018, National Academy of Sciences: Transportation Research Board 2018. Platform doors are increasingly installed by metros, primarily to improve safety. However, they have the potential for both positive and negative operational impacts, mostly by affecting dwell times at stations. Using data from the CoMET and Nova international metro benchmarking consortia of 33 metro systems, this paper seeks to understand and quantify these operational impacts. Overall, platform doors have a net negative impact on dwell times, leading to between 4 and 15 s of extra time per station stop. This is due to the additional time required for the larger doors to open and close, slower passenger movements due to the additional distance between platforms and trains, and, most importantly, extended departure delays after both sets of doors are closed caused by the need to ensure safety (that no one is trapped in the gap between the two sets of doors). This is a particular problem in mainland China, where metros conduct manual safety checks that require drivers to step out of trains onto platforms. However, despite longer dwell times, platform doors have a net positive impact on metro operations, largely due to the many safety benefits that also reduce delays and thereby improve service performance. There are also potential benefits regarding energy and ventilation. To mitigate the negative impacts, metros should seek to refine procedures and improve technology to reduce dwell time delays caused by platform doors. Reducing or eliminating these extra delays are essential to delivering efficient service and maximum capacity, provided that safety can be assured.
Canavan S, Graham DJ, Anderson RJ, et al., 2018, Urban Metro Rail Demand: Evidence from Dynamic Generalized Method of Moments Estimates using Panel Data, Transportation Research Record, ISSN: 0361-1981
© National Academy of Sciences: Transportation Research Board 2018. This paper estimates elasticities of demand for metro services with respect to fares, income, quality of service, population and network length. Data for 32 world metro systems covering the period from 1996 to 2015 are analyzed within a dynamic panel data specification. Three key contributions are made. First, we collate a database for estimation that is more extensive than that used in previous studies. Second, the quality of the data we have available allows us to more accurately represent quality of service than has been possible previously. Lastly, we estimate and compare two different measures of demand. Our analysis finds a statistically significant negative fare elasticity of −0.25 in the long run for a passenger km specified model and −0.4 in the long run for a passenger journey specified model, and a positive long run income elasticity of 0.17 and 0.18 for the passenger km and passenger journey models respectively. Regarding quality of service, we find positive long run elasticities of 0.56 and 0.47 for the passenger km and passenger journey models respectively. Income levels, population, and the size of the network are also found to be statistically significant and positive in nature. The results suggest passenger km and passenger journeys will increase more in response to changes in service (here represented by increased capacity) than to changes in fares, with the difference in elasticities of service and fares being more pronounced for passenger km.

Horcher D, Graham DJ, Anderson RJ, 2016, Merging smart card data and train movement data: How to assign trips to trains?, Merging smart card data and train movement data: How to assign trips to trains?
This report explains the assignment method applied to link trips compiled in smart card data to train movements recorded in the signalling system. Particular attention has been paid to (1) origin-destination pairs with multiple potential route options, (2) peak-hour trips delayed by di culties in boarding crowded trains at the origin station, and (3) trips originating or ending on rail lines not included in the train movement dataset.In the current version of this paper the metro network on which the method has been applied is anonymised.

Metro automation is an increasing trend worldwide. This study investigated the realities of operating automated lines, focused on the following key questions: What staffing levels are used by metros, and what are the pros and consof each approach? Under what circumstances do metros choose to staff all trains on linesthat are capable of unattended operations? What technology is required to enable automated operations? Do the benefits of automation outweigh the additional investment?

Various issues faced by metro operators for the development of a sustainable metro business are discussed. Government needs to provide some degree of predictability in planning, funding, coordination and regulation. The future cost of poor metro planning is high in physical, financial and operational terms, yet the resources put in and their output are often poor. The main requirement to develop a sustainable metro business is the active engagement of government with operator for issues that affect the operator.
Anderson RJ, Hirsch R, Trompet M, et al., 2003, Developing Benchmarking methodologies for Rail Infrastructure Maintenance Management Companies, European Transport Conference
Public transport benchmarking has been growing in use. However, a recent literature review carried out by the authors has revealed that its practical adaptation to the railway industry has largely been confined to either the operation of trains, or the operation of single, vertically integrated railways. The paper describes methodologies developed and tested for the benchmarking of railway infrastructure companies. Much of the work has been conducted as part of a 5th Framework research project for the European Commission (IMPROVERAIL: IMPROVEd tools for RAILway capacity and access management). The paper will also present results from a pilot project that applies the methodologies and has involved the participation of several national railway infrastructure providers. It is argued that the benchmarking of complex and heterogeneous railway infrastructure companies presents particular problems. These must be overcome if any benchmarking process is to yield true comparability and thus any practical value. Railway infrastructure company benchmarking is due to become more important following the vertical separation of trains and infrastructure, not only amongst European Union national railways, but also elsewhere in the world where vertical separation is undertaken within public transport. The approach to benchmarking suggested by the research and applied in the pilot project takes a non-traditional view of railway infrastructure providers, focusing primarily on the concept of entities rather than functions. The traditional view of a railway infrastructure provider is of an organisation made up of a number of separate functions, e.g. operations, engineering, finance, etc. The new approach taken is to look at the entities contained within a railway infrastructure provider. An entity is defined as a product (such as the provision of a defined type of railway infrastructure), an asset or a process. In many cases the management of these entities cuts across functional boundar
