[citation needed] During the COVID-19 pandemic in particular, many cities set up pop-up bike lanes to quickly provide more space and safety for cyclists in poor road traffic conditions.
[5] The COVID-19 pandemic led to the creation of more space for bicycle traffic in Colombia, initially in the capital city of Bogotá, over a total of more than one hundred kilometres of main roads.
Mexico City announced a 54-kilometre pop up lane in Av Insurgentes and Eje 4 to create a mobility alternative to help decrease mass transit agglomeration in Metrobus lines.
[9] The Berlin-Brandenburg regional association of the ADAC criticised the measure and said that the senate would exploit an emergency situation to pursue particular interests.
[5] After a female cyclist coming from a pop-up cycle path was killed by a truck driver turning right at the intersection of Petersburger Straße and Mühsamstraße in June 2020, Siegfried Brockmann, head of the accident research department of the insurers, criticised that pop-up cycle paths alone would not provide a safe solution for the intersection areas as the main danger spots and would thus make people think they were safe.
The senate administration replied that the police were involved in every installation of a pop-up cycle path, "in order to consider safety aspects of the respective location together with the road traffic authority".
The situation at crossroads and junctions would only change as a result of the provisional cycle lanes to the extent that the visibility conditions would improve significantly in each case.
[12] A 2021 case-control study of cities found that redistributing street space for "pop-up bike lanes" during the COVID-19 pandemic leads to large additional increases in cycling.
