Traffic lights need to be installed, majority of commuters and residents have proven that they cant handle the responsibility of a stop sign controlled intersections. Valley has become dangerous for pedestrians and I very rarely see any kind of traffic enforcement in the area. I know this is anecdotal but that's how I see it.

I tend to agree with J about lack of enforcement and ignoring stop signs. I did not comment on the ridiculous poster and cone "test" project near my home as I could not read any of the instructions from my car adding to the traffic hazard at those intersections. If I understand the rationale mentioned here about making the intersection crossing shorter by painting a zone on the street, that makes no sense to me. The street from curb to curb is as wide as it is. You are just measuring from an arbitrary end point. It doesn't actually make the crossing time shorter.
The bollards are the biggest joke in town when it comes to traffic control. An actual traffic control light, MIGHT work, if enforced. But our police force is already being reduced from traffic to serious crime due to staffing and hiring shortages brought on by another set of irresponsible decisions, or lack thereof, by City Council. No contract with police and fire is a major blunder we will suffer from for years.
Maybe the pedestrians could obey the first rule your mother taught them...STOP, LOOK BOTH WAYS, THEN CROSS WHEN SAFE FROM ONCOMING CARS. Most pedestrians I have observed, unless they are in their 70's or 80's, don't even STOP or pause at the intersection or crosswalk. They are entitled to walk right out into the street without regard for approaching traffic. How about fines for pedestrians? Oh never mind, they would not be enforced.
And those riding bikes are already in control of the road by blasting intersections whether there is a stop sign or not, by riding on the sidewalk endangering pedestrians and not using the correct direction in the painted bike lane,. Making car and truck drivers interpret and navigate green bollards in narrower lanes for driving will only cause confusion and likely more accidents. Taking some personal responsibility in this matter would be a good start to making a safer roadway for all users.
