This European Standard covers the ergonomic layout and usability of keypads. The keypad may consist of numeric, command and function keys and alphanumeric characters. On the basis that keypad layout impacts performance (keying speed, and errors), this European Standard aims to: - enhance usability; - ensure ease of use through consistency; - increase customer confidence; - reduce customer error; - improve operating time; - ensure ergonomic data entry. This European Standard specifies the arrangement, the number and location of numeric, function and command keys, including placement of alphabetic characters on numeric keys. Design requirements and recommendations are also provided. This standard applies to all identification card systems with a numeric keypad for use by the public for stationary or non-stationary devices. This standard also covers keypads on touch sensitive devices.

This project specifies the fifth part of the DATEX II European Standard which deals with the one or more publication sub-model(s) within the DATEX II model that support the exchange of measured and elaborated information. These publications are intended to support the exchange of informational content from the organisation having the measures and creating elaborated data to other organisations providing ITS services or onward information exchange. It also includes the exchange of static information about measurement sites. This is specified in three submodels, a DATEX II Measurement Site Table Publication submodel, a DATEX II Measured Data Publication submodel and a DATEX II Elaborated Data Publication submodel.
