NeTEx is a CEN Technical Standard for exchanging Public Transport schedules and related data.
It is divided into three parts, each covering a functional subset of the CEN Transmodel for Public Transport Information:
- Part 1 describes the Public Transport Network topology (CEN/TS 16614-1:2014);
- Part 2 describes Scheduled Timetables (CEN/TS 16614-2:2014);
- Part 3 covers Fare information (CEN/TS 16614-3:2015).
NeTEx is intended to be a general purpose XML format designed for the efficient, updateable exchange of complex transport data among distributed systems. This allows the data to be used in modern web services architectures and to support a wide range of passenger information and operational applications.
Whilst there are a number of existing standards available for Timetables, NeTEx is the first systematically engineered standard that also covers multimodal Fares.
Support and contact requests are managed inside the EU CEF DATA4PT project that involve several member states in charge to imlements National Access Point using NeTEx, Transmodel, and SIRI CEN standards.
