NATIONAL FOREWORD

This Indian Standard (Part 4) which is identical with ISO/TS 17575-4 : 2011 ‘Electronic fee collection - Application interface definition for autonomous systems - Part 4: Roaming’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Intelligent Transport Systems Sectional Committee and approval of the Transport Engineering Division Council.

This standard is published in four parts. Other parts in this series are:

Part 1 Charging

Part 2 Communication and connection to the lower layers

Part 3 Context data

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
