What kinds of feedback does your profession care about? I am constantly frustrated as a pedestrian with the traffic flow and signal timing problems in my area but I feel like it's pointless to submit a complaint to my local municipality because my anecdotal data points will probably be disregarded.

I'm not very good at nor patient for trying to do neighborhood people organization and go around in circles with City Hall for 5 years (as has been the case with other neighborhood things like park use etc. that I have previously been involved in). But I am tried of losing about 5-6 hours a year to excess wait times at intersections despite trying to avoid the slowest crossings.

I've lived a few different places, also working in transportation engineering. I personally care a great deal about accessibility, and would much rather delay cars slightly than pedestrians (for numerous reasons). For example, when reviewing traffic control plans, etc, I always make comments or suggest changes along those lines. But ultimately, it comes down to what the municipality wants to prioritize - unless there are safety issues, it's hard to do more than suggest and push for something better.

If you want to make a difference, making comments (about ongoing projects, particularly) will tend to have more impact. For something more systemic (like light cycles deprioritizing pedestrians), I found the best solution was to move to a better city.

If that's not a solution for you :) then another option you might want to consider is having a meeting with your municipal (or even higher) level elected representative - invite them for a walkthrough of a more problematic space, and try to explain the issues and possible solutions as calmly/rationally as possible. And without attacking car culture directly, as that tends to get people defensive.

Thanks a lot for the feedback. I live near a traffic artery so I've always known there were trade-offs, but the frustration does mount after a while. My #1 beef is when the traffic is paused but you just missed the light change when you hit the ped xing button, and now it's not safe to rely on the light staying green while you dart across.

San Francisco avoids this particular problem by having the walk signal turn on automatically when the car signal is green — no need to hit a button (most intersections don't have buttons at all, and the ones that exist aren't even hooked up to the light).

I don't know if this would translate well to other cities — SF has a very pedestrian-friendly layout with narrow, slow streets , small blocks, and short light cycles — but it works well enough here that it might be worth trying elsewhere.

When I visited Barcelona, I was struck by their intersection design. It's great.

Instead of squares, their streets intersect in diamonds, where the (largely one-way) streets come out of the corners. They're a bit larger than a square intersection-- it's like you took the square, and then filled in four right triangles at each of the corners.

The main effect is that crosswalks are significantly pushed back from the intersection center. As a pedestrian, there's far less ambiguity about where the cars are going (regardless of whether they use their signal). Same for drivers: you never have to wonder which way a pedestrian is gong to cross when they're standing at a corner where two crosswalks meet, because there are no such corners.

Of course, this also makes intersections much bigger. This is offset by having parking spaces along the edges of intersections.

That might be great if you're visiting or just out for a stroll.

But let me tell you, it can be infuriating if you're walking to actually get somewhere. The city I live in has been replacing 2-way and 4-way stops with roundabouts, which has a similar effect of moving the crosswalks away from the intersection. Now it takes much longer to walk anywhere because you keep having to detour out of your way to cross the street.

Yes, 'beg buttons' are awful (as are the 'red-revert' signal designs you allude to).

Can you or any other traffic engineers here tell me why we find it acceptable that cars are allowed to make unprotected left turns while pedestrians have a walk signal? Right turn on red is bad enough, but unprotected lefts give drivers a direct incentive to torpedo into crossing cyclists / pedestrians, as slowing down would mean a collision with oncoming traffic! Too many intersections in downtown Atlanta, for instance, have no left turn arrow, and I felt constantly in danger.

Most North American road infrastructure has been rebuilt over the last century to be automobile-centric. "We" deem that conflict to be acceptable because the alternative is more complicated phasing - most of which results in delays to car traffic (and pedestrians!), and so most places won't accept it. For details, here's [1] a document that outlines the tradeoffs in various different signal phasing designs.

TL;DR is that "we" won't prioritize any road user except the automobile.

I agree completely with this comment. Most places signal timing is done with the main scoring metric of reducing vehicle delay. Pedestrians are just an after thought that can be squeezed into a vehicle specific timing plan. As an example, how often do you see a pedestrian scramble, walk signals in all directions, outside of somewhere like Time Square?

[benrbray]

Some of the problematic intersections in Atlanta have slowly been replaced with scrambles, and it's amazing as a pedestrian. I hope to see more and more of those!
