79Second, a targeted measure for the retention of traffic and location data may, at the choice of the national legislature and in strict compliance with the principle of proportionality, also be set using a geographical criterion where the competent national authorities consider, on the basis of objective and non-discriminatory factors, that there exists, in one or more geographical areas, a situation characterised by a high risk of preparation for or commission of serious criminal offences. Those areas may include places with a high incidence of serious crime, places that are particularly vulnerable to serious crime, such as places or infrastructure which regularly receive a very high volume of visitors, or strategic locations, such as airports, stations, maritime ports or tollbooth areas (see, to that effect, judgment of 6 October 2020, La Quadrature du Net and Others, C‑511/18, C‑512/18 and C‑520/18, EU:C:2020:791, paragraphs 150 and the case-law cited).
