My March story for @forbes has just gone live. It's all about pedestrian crossings and how the timings they're based on no longer match the demographics of our cities - research from the University of Bath

Fewer Than 2% Of Older Pedestrians Can Cross The Street In Time

The length of the green signal on pedestrian crossings assumes that people can walk at a speed of 1.2 m/s. Scientists find that very few older people can walk that fast.

@LaurieWinkless @forbes a 72 yr old cyclist died crossing a street (CA US, yrs ago). Police said she ran a red light (per the driver that hit her). Our crosswalks have quick times normally, then extend to 30 seconds if a pedestrian pushes the button. (Not sure if the "yellow" time extends.)
If the cyclist approached the intersection while it was green, she wouldn't have stopped to push the button. My guess is that it turned yellow, then red before she got across.
Advocates argued for a median refuge island.
It was not implemented.
