‘All’ about privacy in the Talking Traffic data chain

How exactly does the public-private Talking Traffic data chain function? What data are exchanged? What are the risks in the area of privacy and security? And how do partners manage these high-risk aspects? Who is responsible for what? The answers to these questions can be found in the recently published ‘Chain-wide Privacy Impact Assessment of Talking Traffic’s Data Chain.’

The 41-page document can be read as a reference work for anyone (including ‘new’ parties and government privacy officials) who wants to know more about the background of the Talking Traffic Partnership. The report, drawn up by the Ministry of Infrastructure and the Environment with contributions from DTV Consultants B.V. and PBLQ, therefore starts with a description of the Talking Traffic data chain.

In addition to the duties and responsibilities of participating Talking Traffic partners, the document describes, inter alia, the requirements in the area of privacy and security, in particular regarding the intelligent traffic light control systems, the ITLCs. Attention is also paid to the most important technical actions in the data chain with regard to privacy. The publication also contains practical control measures. The report is also useful for road managers looking for guidelines to give their responsibilities the right form and substance. The document has two annexes: a top 5 of privacy risks in the chain, and the measured effects of the ITLCs.


A Privacy Impact Analysis (PIA) is an investigation into the consequences for privacy of processing personal data. It is an instrument that systematically maps out which data are being processed, who performs this processing, on what basis, how and what risks that processing entails. Based on the results of a PIA, an organisation can take measures to limit those risks.
