[Electronics-talk] [EXTERNAL] Re: Electronics-talktraffic signal app

It's my understanding that modern traffic signals have sensors that
communicate with traffic conditions, and possibly those could be tapped into
somehow.  I'm not a traffic engineer or an app developer, so that's as far
as I can go.  I just with some bright doctoral candidate would look into it,
instead of inventing vibrating pants or some such other oddness.

But the app would have to be able to communicate with the traffic signal to
obtain its status, so you would still need the help of the local government
to make that happen.

I agree that would be good, but making it happen would take a lot of work.
That's why I'm thinking an app of some sort, or even some stand-alone
device, would be a good thing.  It could be deployed quickly, without
arguing with local government.  It also seems cheaper than deploying lots of
audible signals.  Those who wanted it could use it, and those who didn't
wouldn't.  Of course, it would have to be very reliable, but it could be
very helpful. Now what I need is an app developer.

I feel that if accessible traffic signals are to be deployed, that they
should be deployed wherever there is a traffic light. I feel that this is
the only fair solution, and is born out by the discussion that we have been
having. We have seen that there is a wide range when it comes to the
abilities of blind persons in this arena. What is not a problem to some is a
major problem to someone else. If you only deploy accessible signals at
certain intersections, what cryteria do you use to determine whether or not
a given intersection rates an accessible signal? As someone said, an
intersection with little traffic can be as problematic as an intersection
with heavy traffic. T intersections pose major problems because of the lack
of parallel traffic. Also, an intersection where one street has heavy
traffic, and the intersecting street has little traffic can be problematic.
And the one place where there should always be an accessible signal is at a
round about.

Jim and others,

My understanding, beyond Chris's concerns, is that some feel crossing when
the light is red even without traffic technically puts them in violation of
the law.  I have personally not worried about this, although I tend to
remain careful to listen for on-coming traffic, knowing that somebody might
speed to make it through a light before it changes.

On a related issue, I would really like to understand better how people who
are hearing-impaired deal with this.  On the one hand, I do not want to take
a position that prevents someone from traveling, but I also don't feel I
want to push for accessible lights on intersections that are pretty simple
if they are not truly needed either.  When I cross a street, I am aware that
what I hear may not be as substantial as what others with normal vision see,
but I do feel that I get enough information in most cases to make decisions
about my safety.  For example, one of the bus stops I sometimes use is about
five blocks from my house, and the route there is along a somewhat busy
street without a sidewalk.  I may not be able to hear a car as far away as
someone sees it, but I can hear on-coming cars in plenty of time to be sure
I'm at the edge of the street.  What I would like to understand better is
what people who are hearing-impaired use to make decisions about crossing a
street.  While I consider myself to be safer crossing when the light is
green for me than when it is red, I never feel that the light is truly a
guarantee of my safety.  I would personally not recommend that any blind
person just cross when another person or an APS indicates is it okay without
being very aware of their surroundings such as turning cars, or cars
approaching the intersection at what seems like an unusually fast speed.  

Do people who are severely hearing-impaired have other alternative
techniques that help judge safety, or is it felt that one has the right to
take the risk, if that is what it is?

Best regards,

Steve Jacobson

So Chris, you're saying that you don't trust the traffic to stay quiet Long
enough to get across all lanes?

APS is audio pedestrian signal.

very minimal but I need to cross four lanes of traffic, and due to either
the traffic light patterns or the lack of any preceding traffic signals, the
cars can be traveling quite quickly. I want to make sure I have a full cycle
to cross all four lanes, and I can't do that without the cross traffic in
these situations. I've also crossed streets late at night, again where the
traffic is light, and barely made it across the street before a lone car
came speeding by because I wasn't sure I had the full traffic cycle.
