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. SP22002 is the 2rd revision of the guideline.
3rd revision of the Terms and definitions of Safety related message sets
Selection of DATEX II Situations, DENM and 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.
Thanks to the fruitful collaboration among Car2Car Communication Consortium, Data for Road Safety, DATEX II and TISA a third revision of the “Terms and definitions” has been issued on 19 February 2021. The document provides a subset of DATEX II situations, DENM and TPEG2-TEC causes and TMC Events, which shall be defined and declared as the message sets to be used for safety related messages.

TISA Guideline for Lane Numbering
This document provides a guideline how TPEG applications can number the lanes of roads. The numbering schema allows TPEG applications to address individual lanes along a road and to have a more fine-granular location description.
The schema is applicable to all applications which are using the road network in a digital map. The map needs to support lane level information and provide at least the number of lanes for road stretches.
The numbering schema was introduced during the development of the TPEG2-VLI specification. Also in this application the first implementation has been made. The numbering schema is also part of TPEG2-SPI specification.
The guideline was also shared within the Live Map Delivery Chain TF of the OADF to align the lane related information provided by TISA, NDS and ADASIS: Lane ID convention harmonization. Furthermore a lane reference harmonization exercise was carried out by the TPEG and NDS experts of Elektrobit.
Priority Action B – Two harmonised Declarations of Compliance for Real-time Traffic Information Safety-Related Traffic Information
Delegated Regulation No 2015/962 addresses the provision of EU-wide real-time traffic information services, in accordance with the Directive 2010/40/EU. This Delegated Regulation requests Member States to manage a national access point for real-time traffic data. It also describes the obligation of Member States to carry out an assessment of compliance with this delegated regulation.
Member States may request from road authorities, road operators, digital map producers and service providers to provide specific documents describing the type of data they handle and the quality. These parties shall submit a Declaration of Compliance with the requirements set out in Articles 3 to 10 of the Delegated Regulation.
EU EIP and TISA have collaborated to harmonise this Declaration of Compliance for Delegated Regulation No 2015/962 and this resulted in two harmonised Declaration of Compliance forms (one for Road Authorities, Road Operators, and a second one for Digital Map Producers and Service Providers)
As an outcome of this fruitful cooperation between EU EIP and TISA four 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 – Action B” – for digital map producers and service providers
- A model for the “Uniform Declaration of Compliance – Action B “- for road authorities and road operators
- Interpretation & explanations of terms within the Uniform Declaration of Compliance for Priority Action B

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.
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.

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:
SP16001 – TISA QBench Calculations: describes the steps that are needed to become the TISA QBench score.
SP16002 – TISA 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.
SP16003 – TISA 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.
