From Streetfilms’ animation division comes the third installment of traffic-calming shorts from Elizabeth Press. First she brought you chicanes, then the raised crosswalk. Now comes the diverter, which Elizabeth explains like so:

Diagonal diverters, half closures, entrance barriers, median barriers,
semi-diverters; traffic calming techniques come in all shapes and
sizes. They can help create more livable communities. As demonstrated
in this short animation, once the diverters are in place, traffic
decreases on the side street. Cars on the side street must turn left,
but cyclists can continue straight. This makes the side street safer
for cyclists and pedestrians.
