This 6-cornered mega-pedestrian- deathtrap at the intersection of Clark, Halstead, and Barry is familiar to everyone who lives or shops in Lakeview. This intersection has been very dangerous for many years and calls to city officials have produced no results.
I timed the traffic signals here on my watch and pretty well determined that there's no way someone elderly or mobility-impaired can make it across either Clark or Halstead on the time allocated. Because you're crossing the street diagonally, the walk is longer. Most people can barely make it across on the WALK light even when trotting briskly.
Additionally, traffic on Clark turning right onto Halstead, from either direction, tends to be driving much too fast, and worse, it's easy not to notice pedestrians crossing on the green at the same time you're turning because the obtuse angle of the intersection eases you into the turn without requiring you to slow down to make the turn safely. Motorists tend to turn right without braking at all.
There are so many built-in flaws here that the only way to assure pedestrian safety is to have a WALK only signal for all directions simultaneously, as is done at Clark, Diversey, and Broadway, with simultaneous red lights that permit no turning in either direction, so that pedestrians have an opportunity to cross without encountering vehicles turning corners at top speed.
