OpRa

---

OpRa (Operating Raw Data and statistics exchange) is an CEN (European Committe of Normalization) initiative with main focus on the identification of raw data used in the Public Transport domain to be exchanged, gathered and stored in order to enable Study and Control of Public Transport Service.

Raw data identification is mainly focused on actual and measured information, i.e. Public Transport information which cannot be changed anymore in the future. This information is mainly an output of the Transmodel (TRM) domains

• Part 4: “Operations monitoring  & control”;
• Part 8: “Management Information and statistics“ focused on raw data for indicators calculation.

Those domains describe the recorded reality of operation, like  delays and cancelled vehicle journeys, etc. either through individual measurements at a given sampling interval or in an aggregate ways (statistics).

Scope

OpRa work scope consists in a formal definition of Use Cases for the usage of Public Transport Raw Data, to enable different levels of Analysis of the performed Service.

To do this the main Public Tarsnport phases have been deely analyzed, in particular:

• Strategic Planning: definition of network elements (lines, stops), main service parameters (vehicles sizes, operation intervals, service intervals for important time demand types), and guaranteed interchanges are planned (NeTEx, TRM).
• Tactical Planning: operators plan their resource usage (vehicles, rolling stock, personnel), with detailed timetables for each resource uni (NeTEx , TRM).
• Before Travel: all planned networks and timetables are published. Passengers and other type of clients may plan their use of the offered transportation services via printed and electronic media, and make their reservations as needed (NeTEx, TRM).
• In-Travel: The transportation service is conducted. Real-time information exchange is available while this takes place and may be recorded (SIRI, TRM).
• Study and control: in this stage, operators and authorities review the history of actual operations, which may lead to improvements through operational changes, or an optimization of strategic and tactical planning (OpRa, TRM).

The latter is the PT phase directyly impacted by the OpRa work scope.

In coherence with the CEN working process philosophy, OpRa work scope is aligned with those covered by related PT standards: Transmodel and NeTEx.

History

The idea of OpRa was born in 2015 when few stakeholders agreed to propose the set-up of a dedicated CEN group to study and formalize the usage of indicators in Public Transport. The formal scope proposal has been submitted to CEN in April 2016 and then approved after the usual ballot period by 10 member states,

OpRa became formally a Proposal Work Item (PWI 00278429) and the work started till end of 2017, when preliminary results have been submitted to memeer states to decide if and how to continue. Early 2018 the OpRa work have been approved to be formalized in a Technical Report, that consists in a formal description of the work done.
