Orientation and Mobility: Anatomy of a Stoplight


I really did want to come up with a wittier name for this post, but it is what it is… And today’s lesson was all about intersections controlled with stoplights.

We where at the same area we use last time, and made our way to the intersection I had stopped at before. Elain explained to me that there are two different types of stoplights. One is called a Variable Timed, and the other Fixed Time. You can guess by their names, it’s really simple.

Traffic LightA variable timed intersection is controlled by a stoplight with an embedded pressure plate or wiring that a car rolls over to control the amount of time the light will stay green on the next cycle. – You can usually see the wires or plate in the roadway. A fixed time intersection has a set interval of red to green cycles that will not change… Simple.

Did you know most traffic lights and cross walk lights timing are based on the fact humans walk about 5-feet-per-second? The wider the street, technically the longer the light will stay green, or walk light will stay on. Did you know that on a variable timed intersection, most lights will add about 3-seconds to the light cycle for each car in the line, most times with a maximum up to three cars deep? (That’s about 9 or 10-seconds.)

Man, it turns out mobility instructors really know their stuff!

So any way… We approached and surveyed the intersection. We determined it was a variable timed intersection; the main street cycle was about 30-seconds, and the side street was about 15-seconds. We noted stoplight pedestrian buttons and we talked about there use. Remember to use them when cars are rolling, so they interrupt the cycle; but remember, some may not work, (in our case one was broken).

The button facing into you is used to control that light crossing the street that you are facing, the button should never be behind you, if so, it’s likely not for that street.

We hit the button, lined up, and waited for the light to change. Here it comes, lights green, check left, center, right, all clear, and go! Always noting the danger point and crossing traffic, many intersections, it’s the middle of the cross walk where you could have cars turn in front of you, particularly if a stopped car is to your left.

Not bad, we made it… and now… we do it again! We continued this way making circles around the intersection when it was the proper time to cross; it must have looked funny, because we looped the intersection clockwise about a half-dozen times.

We talked about the dangerous turn-on-red that so many drivers like to do, even though some (a lot) like to ignore the no-turn-on-red signs. She reminded me that pedestrians still have the right-of-way at crossings, and if a car is at a stop, it’s unlikely they will turn on you. – But I still take little comfort in that. This is part of the huge anxiety of street crossings that gets to me. But the only way to get over this fear is to do more street crossings.

So drivers, please put down your cell phone, stop putting on your makeup, don’t pass stopped cars and pay more attention at intersections. Pedestrians have the right-of-way at cross walks, and persons with a white cane or service dog have even more! If you’d just pay attention, the road would be much safer for all of us!

If you blow your horn at me, and flip me the finger… I’m likely to cane your car, you ungrateful 4-wheeled little bastard. – Road rage, blind man style! – I didn’t say that, I deny everything! I didn’t see your car, I swear!

Next week Elaine says we’re going to play in more traffic, and a little busier intersection. Oh the joy! In all I’d have to say I’m still a 3 out of 5 for busy intersections. But a strong 4 out of 5 for lesser intersections.

Lets see what next week brings!

Orientation and Mobility: Stop, Listen, Look


Intersection SignIn this lesson, Elaine took me to an outer part of town, but it happened to be right near our local Middle School, so I did know the location…

The objective was simple, to walk up, down, and around the block, stopping for all open areas (that includes driveways); listening, for cars and the direction of traffic, as of yet still waiting for “All Quiet“; and finally look to make sure all is clear before you cross a driveway or street… and as always, using perfect cane technique.

I made my way to the first street, surveying the location, noting the street name, the flow of traffic, and how the intersection was controlled… listened for “All Quiet” and made my way across… It was mid day so traffic at that time was very light. We made our way down a few more blocks, doing crossings the same way, always stopping, listening for any sound, and then looking before crossing.

This lesson was uneventful, as it was more for Elaine to observe me, and how I approached the curb, and to make sure I listened, and looked before crossing. We made a few turns, and looped back around.

While doing so Elaine normally travels a good 20 to 30-feet behind me as to not disturb me, and so she can observe.

As I walked down the street some people where out and about. As I approached an alley way I stop, and listen, check the curb edge with my cane as I have been told to do. While resting a moment I hear from across the street a man say “It’s OK, your fine it’s clear…” as I did then step off and cross the alley, I then hear “Watch your step…” of course I did politely ignore him.

White Cane ManI made my way down the street, and I over hear him and a lady say “Leave the man alone, he knows what he’s doing“… and a fleeting comment of “Them blind people sure amaze me, I don’t know how they do it…” – Well I have to say at least some one noticed my white cane! In all my years, I have never had some one attempt to assist me in crossing a street. It was a little embarrassing, but made me feel good, some one attempted to help.

As a note to my fellow sighted reader, I would like to remind you that most blind or low vision people who travel need little help, and if we do, we will ask. We know what we’re doing that’s why we have people like Elaine to train us!

You should not shout or startle a blind or low vision person; chances are they are concentrating on the task at hand… You should not yell “It’s OK to cross“, I will cross when I am ready… If I am going to cross a street, chances are I am at the curb, with my cane in front of me, waiting to step off. If I am not going to cross, I will likely pull my cane tight to my body, and be back away from the curb. – Please do not be offended if I tell you I don’t need your help.

In the next lesson, Elaine says we’re going to start working on crossing streets where traffic is a little more heavy, and you can’t always wait for “All Quiet“…

As always, feel free to leave your comments!

Well it was raining and cold outside so today’s lesson was again at the local mall. So that is where Elaine and I headed today, a bit puzzled as to what she possibly may have me do.

Mobility instructors like to play pretend to educate and prepare there students for the next step, and it is kind of fun. So today Elaine played the role of a bus or Paratransit, which ever you would prefer.

With instructions and a task for me to do. The task was to be dropped off ALONE at the main entrance to the mall (an area where a bus would normally stop), enter, and make my way to Borders Books… ask the clerk for a book price, and if it was in, (sorry I forget the name of the book.)… Navigate out, and threw the mall, and meet Elaine at Friendly’s and the entrance to Boscov’s…

So off I set on my mall adventure. Not hard you think, but you must remember, I’m not use to being alone in such a large place, I’m always with friends, family, or mom. This time it was up to me, to navigate myself it’s a bit nerve-racking .

compus

I navigated myself threw Dick’s Sporting Goods, (the main entrance), then into the mall… located Borders Books (only a short walk from Dick’s.) and I entered the book store. A nice clerk asked me right away if I needed help finding something, so I asked about the book and got the information Elaine asked for.

The first task complete, I exited and set off for Friendly’s all the way on the other side of the mall. Our local mall is not huge, but it was a good walk away. I had to navigate some steps and make a turn to head near Friendly’s, thankfully it was not crowded at 2PM on a Wednesday afternoon. I did know where I was going, after all this IS our local mall…. And there was Elaine waiting for me… (Sorry no ice cream though!)…

The lessons second half took place in Boscov’s, at the steps… We reviewed cane step technique. We then talked about escalators, and noted how the steps move, and the sounds they make.

EscalatorHere come them blinder glasses again… Elaine lead me around the store a bit using sighted guide technique to “get me lost“… and we approached the escalators again… by sound I knew we were close… Feel the rail she says, it’s pulling away, extend the cane and feel it catch the moving steps and how it pulls away; lift-click, lift-click, lift-click, as it lifts the cane. We must be going to head up… We did… Cool!

Now we walk around a bit again to confuse me, remember with the blinder glasses I cannot see at all. We approached the escalator again, feel the rail, it’s pulling away… we know at least it’s not the down escalator or it would be “pushing” us not “pulling“… I extend the cane to feel it catch the moving steps and how it pulls away; pull-tap, pull-tap, pull-tap… wait a minute, something’s different…

Elaine explained that sound and the LIFT of the cane is the key… Either escalator will pull you on, but how do you know if you are going upstairs or downstairs, escalator on-platforms are flat… Going up you’ll hear the pronounced CLICK as the cane LIFTS AND DROPS on each step. For a down escalator you will hear more of a TAP then a click, and the cane won’t be lifted, just be pulled… A eureka moment for sure! We went up and down a few more times, with no trouble.

The elevator lesson was very short. Only to mention that most elevators beep or chime for each floor you are on, and to count the beeps to determine what floor you’re on. Since our Boscov’s only has three floors, counting the roof parking, we will need to review this lesson in a bigger building and a better functioning elevator.

With tasks complete, I was told to navigate back threw the mall again, alone, but this time meet Elaine at TGI Friday’s… And while I’m at it, stop in, and ask for a take-out menu. So off I set. – Not many problems, I made one tiny wrong turn, but realized it right way, and made it OK. Popped in, asked for a menu, and met Elaine at the door. – Be noted, I didn’t care for inside Friday’s it’s kind of dark, and bar like, I dislike dark restaurants, it’s even harder for me to see.

compusI then navigated AGAIN back threw the mall to Dick’s Sporting Goods to meet Elaine, and we left… In all this lesson went well, and Elaine says I am picking things up very fast. With hopefully nicer weather next week, we will do more street work, as that is where I still need the most help.

As for roaming the mall by my self, my comfort level was around a 3 out of 5, even though it was our local mall, I am still not use to navigating large places by my self. We will work on this. Elaine says we just need a bigger mall! – Oh joy! Yes it’s true, we do have the King of Prussia Mall here in PA, and it’s the largest shopping mall on the East Coast of the United States… Crap… – Well, at least there is an Apple Store in there!

Till next time! Please as always feel free to leave your comments!
