All of the signals on this section of Columbus Blvd need to be synchronized. The massive backups that occur here are solely due to poor signal timing.

Are you a traffic engineer? I'm curious because I see you've reported a lot of issues about traffic management.
As a non-motorist, I am concerned about the already speedy traffic on Columbus, where speed limits are not enforced. From my perspective, traffic is already dangerously fast. I-95 is right there if motorists need to travel at 55+.
Can you offer some details about the precise stretch of lights that need to be synched and how the timing should be changed?

Sure. What I'm looking for is not faster vehicular movement, but smoother movement. Synchronizing signals allows a traffic engineer to set a precise speed at which vehicles will hit a "green wave" of lights. This can actually slow traffic down, as vehicles will no longer race the lights to make sure they will catch an already-stale green.
The specific signals in question are all those between Washington Ave. and the second (ie, I-95 N only) I-95 entrance ramp.
The signals should be set up to provide a northbound green wave, as northbound traffic is usually much worse because of the plethora of left turns. The green wave should be timed to provide speeds around the posted 35 MPH limit.
This will even the flow of traffic. No longer will you, as the pedestrian or bicyclist, need to worry about whether a taxi is going by at 60 or 20; all traffic will move smoothly at the speed of the green wave.
Remember, speed is not prima facie dangerous; it is unpredictability that causes collisions.

A traffic study is being done on Delaware Ave that will address this problem.
