• Change the stop lights to something that warns of oncoming or crossing traffic, like flashing lights and signs. Traditional STOP/GO systems don’t work well for intermittent traffic (is any cyclist or ped really gonna wait on a red while there’s no immediate cross traffic?). Instead, go for visibility and awareness, and people’s desire to not collide with one another will prevail.

• Increase the amount of two-way lanes for non-ped traffic. It’s crazy that the 72nd St transverse is the only place with bike lanes going in both directions, though I understand this is probably a holdover from when cars were on the Drive. Maybe some kind of flex lane in certain areas, where one direction of traffic has priority.

• Create a system that uses the language of speed and direction, rather than means of locomotion. In other worlds, group like with like according to where and how fast they’re going.
