The desire path is probably on private property, they're not going to buy all that to build a sidewalk

Edit - yep! There's three lots in that corner, one of which has the existing house. The other two lots are undeveloped, where the beaten footpath is located.

That was what I was thinking, although I see how my post didn’t express that well.

Thanks for the fence logic.

So what is a traffic engineer anyway?

In the UK I know we have civil engineers, highways engineers, transport planners and urban designers but nothing with that specific title.

Here in Dallas, we try to find the busiest highway in the metro, come up with a plan on how to fawk over the traveling public with a terrible traffic control plan in order to build what we try to pass off as an improvement to traffic flow.

Note, the linear park is a major water pipeline for the city, so nothing can go lower. That level crossing is being removed in the next 3 years, rail over road solution has been chosen I believe:

This intersection seems like an easy fix:



Except, you can't touch the triangle in the middle because it's historic, and you can't touch the building south east of the church because it's infrastructure.

Why is the building southeast of the church considered infrastructure? Or are you referring to the post office?

Expand the square and shift it east, while converting the intersection into a T Junction. The square is improved and more accessible, while traffic is safer and more streamlined.

Let's get a little crazy. Let's have some fun.
It's because of trams, since right-turning traffic would normally block the ROW.

When you see it in practice (I think it's only right in the middle of Melbourne that hook turns are needed anyway) it makes sense.

As for the Library Square example, I dunno how much traffic the two side streets generate (the neighbourhood doesn't strike me as vibrant) but maybe just do some annoying poo poo with the synching of the traffic lights and call it a day.

What is it, the Verizon building? I'd do three concepts, show the property takes for keep north, keep south leg, and meet half way. Half way would probably end up being most expensive in this case since you'd probably be hitting the main structures of the big properties, but people like to see lots of options.

The property takes/utility relocation for keeping the north leg would probably be really high. The historic impacts to the park might not look so bad with that context.

You have traffic signals with multi-lane approaches - it almost certainly has the volume to make a traffic circle (and not a modern roundabout) unworkable. Roundabout would have more property impacts compared to a signalized intersection, not less.

Opt 1 keeps the south leg intact
Opt 2 keeps the north leg intact
Opt 3 splits the difference and goes through the middle

All three would obviously need refinements, I usually design in Microstation and not Microsoft Paint, no effort made for radii, etc

This type of study would only be done if there was a serious issue - safety, traffic, etc. The property impacts are obviously very large and expensive. I worked on a similar project where there was road widening programmed, and this type of 'dog-leg intersection' was acting as a major obstacle to getting the future widening done. I think it ended up being about a $4M project, maybe more.

Sometimes they think that until we do a concept that shows a $1M project with historic impacts vs. a $5M project with no historic impacts, then they realize they're on board with spending $200k for NEPA work by our planning folks, plus some remediation/relocation of monument, etc.

Good idea - they could do a land swap and put the new parking lot where the existing road is - wipe out the house or two to the south.

I like this solution, assuming the turning radiuses are sufficient. Though I'd also include cutting out Library Road entirely and incorporate that land into the park, since there's Main St right next to it.

This is probably the best solution if the constraints are "change nothing, but make it better".

Check the other side of the park. I'm pretty sure that's a war memorial.
