Appears the Green Wave is getting ever more savvy as well: "On certain stretches, LED lights embedded in the asphalt help cyclists keep their speed in order to catch the green light at the upcoming intersection and there are simple speed radar signs reminding cyclists to maintain 20km/h in order to surf the wave. Version 2.0 is currently being tested, with sensors able to register a group of citizens riding together and then keeping the light at the intersection they’re approaching green for a little longer."
