  During the Corona crisis measures were taken to avoid the spread of the
virus, and one of the most important was to 'keep sufficient distance'. In this
period cyclists were facilitated in distancing by the widening of cycle paths,
or the use of car lanes. The Corona measures also affected intersection
control, since one of the principles of signalizing is based on clustering of
traffic. The settings of the control take into account the way cyclists tend to
cluster close together at the stop line, so for optimal control, if the
clustering changes, the control should be adapted as well. This paper presents
measures for 'Corona-safe' intersection control for cyclists, and discusses the
effect of the measures and their (dis)advantages. Further it was investigated
how some municipalities used these measures and conveyed about it in the media
and how these measures were received by the public. The measures can be divided
in two groups: detection and timing. For the municipalities considered, the
least popular measures concerned the detection methods, such as adaptations in
use, or type, of push button, since the negative aspects can be large (effect
on throughput and costs). More popular were changes in the timing of the
control, the most conveyed measures being more frequent and longer green for
cyclists. The acceptance of the measures by the public (determined via
reactions on social media) is mixed, some are positive about the improved
control, others negative (effect on car traffic or costs). The most common
reactions are general complaints about intersection control, and about cyclists
behaviour. For future use the measure 'more frequent green' is most suitable,
permitted cyclists are detected to support the acceptance of the control. Also
bicycle apps can be applied, since these results in more comfort and have
limited negative effects.
