Integrating driving advice with safeworking displays

Safeworking systems such as the European Train Control System (ETCS), the Australian Advanced Train Management System (ATMS) and Positive Train Control (PTC) in the USA are designed to, amongst other things, inform drivers about safe train operation by displaying (and enforcing) speed limits, limits of authority, and braking curves. Driver advice systems are designed to provide information about efficient operation. As well as reducing energy use, driver advice systems can improve traffic flow by pacing trains to avoid safeworking delays. Ideally the advice from safeworking systems and advice systems should be combined. There are several issues to be addressed if driving advice is to be incorporated with safeworking information: driving advice is calculated to the next timing point, which may be beyond the current limit of authority, the advised speed profile should not be displayed beyond the safe speed profile; the Power and Coast driving modes require specific control actions and cannot be indicated effectively by just a target speed; and and the advised speed profile, if displayed, should not reduce the clarity of safeworking information. This paper discusses ways that efficient driving advice can be incorporated into ETCS, ATMS and PTC displays without compromising the safety of the safeworking system or the effectiveness of the driver advice system.
