I would like to see this in Ontario, especially in rural and northern areas:
If this trial run proves successful, glow in the dark lane markings might become commonplace all over Australia Hard to see lane markings at night, particularly in places without proper street lighting, might become a thing of the past if this trial run headed by VicRoads of Victoria, Australia...

Some drawbacks:
“Since the road markings were put in place two weeks ago it has been reported that some drivers were driving along the road in the dark with their headlights switched off so that they could experience the glow in the dark effect,” the BBC reports.
Drivers also soon found out, an unfortunate observation confirmed by civil engineers in charge, that “road markings were sensitive to large amounts of moisture due to rainfall.”
Reflectors embedded in the road would probably work better.
