Title: Closer to Hart Bridge ramps coming down
Post by: bl8jaxnative on January 17, 2020, 10:46:39 AM

Looks like we're a bit closer to reducing  the ramps over by the stadium.

The amount of torque to be used as people accelerate towards the remaining ramps will be incredible.

Torque doesn't cause acceleration, power does.

Also, what are you trying to say?

Oops.

Since this project looks to be happening without any improvements to make it anything other than a street-level expressway with a traffic light, people will stop for that light and then immediately speed up to get back onto the other ramp.

^You're right. They'll also speed up coming down the ramps, in order to beat the red light.

I was just being pedantic and kidding around about the torque/power misconception.

As for the speeding, I think there's gonna be a lot more traffic lights on this project than most would think. There's too many moving parts to keep this all free-flow, lotsa signalization seems almost necessary to keep merging traffic and cross traffic in order.

The mainline has two lights, a ramp and an interchange. Unless they put fences up to channel pedestrians to those two lights, you'll have jaywalking between the ramps to deal with as well. Especially during special events.

I don't think so... There's a signal at the existing crosswalk on Gator Bowl Blvd which I fully expect to be retained, there's got to be one where the ramps near Intuition come down Eastbound, there's got to be a couple on the new intersection with Gator Bowl Blvd. There will be at least 3 places to cross the new roadway based on the concepts we've been shown.

Intuition is west of the ramp at A. Philip Randolph. These are the only two marked crossings between the ramps (both of which are more dangerous than current conditions).

In addition, people will jaywalk unless there are physical barriers driving pedestrians to the marked crossings.

In this area, that should be changed to "Lot J Walk!"  Haha.

I respect what you did here.

Hmmm, is this a sign that Lot J, and even the convention center might happen? They sure are keeping secrets and then bam! They hit us with it.

This is Jacksonville. I can see the ramps coming down....and nothing at all being built. But demolishing something?? Absolutely!!

there likely won't be a red light - all but one light has been removed from the current plan - all that remains are two pedestrian-activated crosswalk signals

Are you saying the two signals where the new ramp at the east end, to/from the Hart Bridge, are "gone" or that they are "pedestrian activated"?  It looks like they are necessary to make safe the left turns to/from the north/south portion of Gator Bowl Boulevard.

^ plans have changed since those that are shown (from April 2019). From what I understand, there are no regular traffic signals - only two corssing signals that are pedestrian activated.

Besides the current location, where is the other ped crossing?
Seems that removing the signals on the east end will cause traffic and safety problems, especially on event days.

Pedestrian activated signals on a high speed roadway are a death trap. Did they not just see what happened on SR A1A in Brevard County over the holidays?

The Sunday crosswalk crash has ignited social media criticism of the Florida Department of Transportation's new SR A1A mid-block crosswalks, where pedestrians push buttons to activate flashing yellow warning lights.

The girl was struck at 5:37 p.m. Sunday by a northbound vehicle near Ellwood Avenue, Satellite Beach police reported in a press release. Mark Nelson said his daughter pressed the button and activated the lights, waited for several cars to pass, then stepped into the crosswalk during a "long gap" before the next car. But the oncoming vehicle did not stop and struck her, he said

Speed probably wasn't the issue.   According to FDOT & others data, that crosswalk is in the middle of a stretch of A1A that's set up like the usual STROAD and, worse, even though it's inbetween residential and the beach, goes for nearly 3 miles without a traffic light.   

That is, nothing is creating breaks in the traffic for pedestrians.   Throwing a ped crossing light at it helps but isn't the same.
