Guidelines for TMC conflation

The act of creating and encoding a TMC in a digital map involves an interpretation of the road geometries at each location. Different digital map makers may implement TMC Location Tables in slightly different ways, which may be reasonable interpretations when viewed in isolation.
However, this may lead to some users of TMC tables (table owner, map provider, traffic provider, client device) interpreting a table differently, resulting in unexpected behavior.
A Task force within TISA has produced a set of agreed upon guidelines, which include a number of example scenarios, to assist users of TMC tables (table owners, map providers, traffic providers, client devices) to have a uniform interpretation of information contained within the traffic table.

Priority Action C – Harmonised Declaration of Compliance for Safety-Related Traffic Information

Delegated Regulation No 886/2013 addresses the provision of road safety-related traffic information, following Priority Action C of the Directive 2010/40/EU. This Delegated Regulation requests Member States to manage a national access point for safety-related traffic data. It also describes the obligation of Member States to carry out an assessment of compliance of the parties addressed by this delegated regulation, i.e. Public and Private Road Operators, Traffic Information Service Providers, Data Suppliers and Broadcasters dedicated to road traffic. These parties shall submit a Declaration of Compliance in accordance with the requirements set out in Articles 3 to 8 of the Delegated Regulation.

EU EIP and TISA have collaborated in a series of workshops to harmonise this Declaration of Compliance for Delegated Regulation No 886/2013.

As an outcome of this fruitful cooperation between EU EIP and TISA three documents have been produced and are now publicly available on the TISA website and EU EIP website.

  • An Introduction letter
  • A model form for the “Uniform Declaration of Compliance for Priority Action C”
  • Definitions & explanations of terms within the Uniform Declaration of Compliance for Priority Action C.

Safety related message sets – Selection of DATEX II Codes, DENM Event Types, TPEG2-TEC-Causes and TMC-Events for EC high level Categories

In the Directive 2010/40/EU (“ITS Directive”) the European Commission developed as Priority Action C a EU Regulation named “Data and procedures for the provision, where possible, of road safety related minimum universal traffic information free of charge to users”. It defines, amongst others a single list of categories for safety related traffic information to be provided without additional cost for the end user.

The ITS Directive Working Group has produced “Terms and definitions” that provides a subset of DATEX II Codes, DENM Event Types, TPEG-TEC causes and TMC Events, which shall be defined and declared as the message sets to be used for safety related messages. Further, for the selected message sets, a correlation the between the three standards DATEX II, DENM TMC and TPEG is defined.

TISA QBench is a method that measures the quality of Traffic Flow information. It will make a comparison between the reality (“ground truth”) and what is being reported by a service provider.

The TISA QBench Task Force has created the following documents to assist the membership in calculating TISA QBench scores:

SP16001TISA QBench Calculations: describes the steps that are needed to become the TISA QBench score.
SP16002TISA QBench Guidelines outlines the purpose, limitations and expected outcomes of the Calculations. How the calculations should be performed and how the results should be interpreted.
SP16003TISA QBench Test Data Sets are added to ensure the correct implementation of the TISA QBench Calculations (including 8 sets of test data are provided in a zip file

TISA – Terms and Definitions for the Traffic and Travel Information Value Chain

The TISA generic value chain is based upon the experience of many members, mainly in the European context. TISA has a policy of sharing experience on a worldwide basis and additional/other value chain elements may be included in the future.

The definitions provided in this document may be used as a reference and should aid the communication between stakeholders along the TTI value chain.
