Using the travelling task as a tool to define its requirements for elderly and disabled people

This paper describes the methods and tools used by the TELSCAN project to identify the requirements of elderly and disabled (E&D) travellers with various types of functional impairments. A Definition of the Travelling Task for different modes of private and public transport was used to capture the needs of E&D travellers through interviews with experts and focus groups with users. The data collection resulted in a generic specification of user requirements, in general and those specific to telematics, for elderly and disabled travellers. This methodology and data can guide the design of ITS and can provide a stepping stone to capture system-specific data to ensure that the needs of elderly and disabled people are included in the design process.
