Qualitraffic - Quality of traffic information (VSS2001/901)
Overview
Background & policy context:
Several projects have been elaborated in the field of quality of traffic information:
- CORVETTE, RDS-TMC in the Alpine region, EU research project as part of TEN-T
- ENTERPRICE, EU research project in the 4th Framework Programme for Traffic Information / Traffic Management
- TRANS3, EU research project in the 5th Framework Programme for intermodal traffic information and route planner
- VSS research contract 15/88: The data integrity in road databases with regard to the exchange of data
- NAVIS National Traffic Information System, preliminary analysis and approach to building a traffic information system for the collection, processing and dissemination of traffic information
- Field Trial RDS-TMC (Radio Data System Traffic Message Channel)
- NRP 41, module E3, Banques de données et routières mobilité: Apport the BDR aux instruments de la gestion de la mobilité
- VSS research contract 01/98: Swiss platform for traffic information: inventory
- SVI research contract 47/98: uses of Floating Car Data in transport planning
- The Networked Vehicle - transport telematics in road and rail, technology assessment on behalf of the Swiss Science and Technology Council
There was a need of a basis for a Swiss standard "Quality Requirements for Traffic and Travel Information"
Objectives:
In the "Qualitraffic" project the basis for a Swiss standard "Quality Requirements for Traffic and Travel Information" is elaborated.
The idea of the quality determination is to compare the generated traffic and travel information (TTI) with the real-life situation, where information are recorded independently and reliably, with respect to topicality, correctness and completeness.
A continuous quality monitoring will be established independently on the technical form of the information, attaining the comparability of information from different sources and processed in different ways, and imposing requirements with respect to the quality of the information content, for the development and operation of TTI systems.
Methodology:
The project will be developed in the following work-packages:
- Analysis of the current situation and definition of requirements based on interviews with key stakeholders
- Development of criteria and structure of quality criteria - In the second work package the quality criteria are defined, on the basis that will be used for subsequent monitoring or measurement of the quality of traffic information.
- Description of the conditions of use - The third work package is concerned with the definition of terms related to the traffic information, which must be complied with in the various applications.
- Creation of draft standard and the Research Report.
The project consists of the following steps:
- Elaboration of methods for the assessment of traffic and travel information (TTI) according to quality criteria, to be able to compare TTI from different sources and with different ways of processing.
- Collection of quality criteria according to different TTI contents and different quality aspects, to be applied in the assessment.
- Definition of quality classes in such a way that a sample of TTI from one provider may be assigned to a specific quality class.
- Elaboration of requirements on recordings for the quality assessment, in order to implement a continuous quality monitoring, being compatible with the ISO 9001 standard.
