Serbian term (edited): naizmenično propuštanje vozila

O3.22.7 For very short lengths of alternate traffic movement, manually rotated signs at one end or in the
middle will suffice, but if the distance exceeds about 20 m, the control should be operated at both ends. If
remotely-controlled signs are used, the distance of 20 m may be exceeded if a risk assessment has shown that
the presence of an operator is not necessary for drivers to obey the signs. However, the operator shall have a
clear view of each approach to the control points.

1. Extend the traffic lights system for one of the following (increasingly complex) situations:
~ pedestrian crossing: two sets of lights operating in tandem, plus stop-go lights for the pedestrians
~ road works: two sets controlling alternate traffic flows, with a ‘both red’ safety period in between
~ T-junction: three sets, with two for ‘straight across’ operating in tandem, and alternating with the side road
~ crossroads: four sets, with each pair operating in tandem, but alternating with the other pair
~ T-junction or crossroads as above, plus one or more ‘left filter’ lights..
