Teaching situation of uncertainty. - ✔✔You need to be able to recognize the situations of uncertainty.
Should know how to ascertain the level of risk involved in crossing during the gaps in traffic.
The risk that a vehicle which is undetected when the crossing was started will reach the crosswalk before
crossing is completed
Technique for crossing at an uncontrolled crossing using visual strategies - ✔✔1. Visually see if there are
cars coming and go when no traffic is present that is close enough to reach the crosswalk before
completing the crossing
2. Cross when you see a vehicle in the nearest parallel lane on the parallel street is just entering the
intersection
Technique for crossing at an uncontrolled crossing using auditory strategies - ✔✔1. Listening for when
they do not hear any cars and cross when it is clear.
3. Listening to hear when a vehicle in the nearest lane on the parallel street is just entering the intersection
Technique for crossing at a stop sign controlled crossing using visual strategies - ✔✔1. When you don't
see traffic or cars at the stop sign

2. When you see that the cars are stopped at the stop sign
3. When you see the protective lane move
Technique for crossing at a stop sign controlled crossing with auditory strategies - ✔✔1. Listening for no
cars at the stop sign and go when it is all clear
2. Listening for when the protective lane starts moving and gets in the middle of the crossing
Technique for crossing at a signal controlled crossing using visual strategies - ✔✔1. Using pedestrian
pushbutton
3. Street crossing with the surge of parallel traffic, recommended when dealing with designated left turn
lane
3. Look at the traffic signal for the perpendicular street to determine the color of the signal of the parallel
traffic
Technique for crossing at a signal controlled crossing using auditory strategies - ✔✔1. Crossing clockwise
and counterclockwise
2. Using aps when available and appropriate
3. Near lane parallel through traffic for dealing with left turn arrow and for complex signal
4. Crossing with surge of parallel traffic
Define a situation of uncertainty - ✔✔A situation of uncertainty is for a gap of judgment because of
undetected vehicles may be just a few seconds away
Pedestrian button in the timing of street crossing - ✔✔The signal notifies the pedestrian of the onset and
duration of the walk signal that is the timing during which pedestrian may legally cross

APS information is supplemental to traffic and environment cues and the APS walk indicator only that
the walk sign is on not that it is safe to cross
What strategies should be used when teaching a learner to use APS - ✔✔1. Approach the intersection and
stop at the curv, maintaining initial alignment, check alignment by listening to traffic
2. Determine the starting location for crossing and identify tactile cues to realign after pressing the
pushbutton
What strategies should be used when teaching a learner to use APS continued 1 - ✔✔3. Listen and
evaluate the intersection, determine the traffic pattern and intersection geometry
4. Leave the curb search for a APS using systematic pattern, starting by making a 180 degree turn and
looking on the side of the curb
What strategies should be used when teaching a learner to use APS continued 2 - ✔✔5. Once located,
explore the device and it's functioning, including if there is a tactile arrow and confirm it is pointing the
direction you want to cross
6. stand at the pushbutton and while maintaining awareness of crossing location, listen to traffic and the
APS for a full cycle to make sure that the sidewalk corresponds with the information
What strategies should be used when teaching a learner to use APS continued 3 - ✔✔7. Press the button
at the beginning of the perpendicular surge and return to the spot
8. When the walk indicator is hears confirm with traffic sounds and cross
Identify and describe a tactile method of alignment at street crossings - ✔✔1. Alignment with grass line-
traveler locates the grass-line farthest from the parallel street and sidestep to it, traveler uses the foot to
establish a parallel direction with grass-line the rest of the body is then positioned according

Perpendicular alignment with curb - ✔✔Traveler has prior knowledge of the curb, the toes are extended
over the curb in order to feel the curb edge under foot, having established perpendicular alignment, the
traveler projects this into space
Maintaining alignment - ✔✔Traveler acquires a straight line and continues this line to the curb, the
traveler mentally projects this line across the street
Identify and describe an auditory method of alignment at a street crossing - ✔✔1. Parallel alignment
requires tracking individual cars into the distance and aligning the body correctly
2. Perpendicular alignment requires the traveler to square his shoulder to the traffic at its farthest point
When should an instructor be positioned while on the corner before initiating the crossing - ✔✔At the
point where they can see both the incoming traffic and the traveler
In the beginning they should be close enough to stop the traveler (no more than 5 feet)
Where should an instructor be positioned after the learner initiates the crossing, during the crossing -
✔✔Between the traveler and the stopped cars
What is the basic procedure for bus travel - ✔✔1. Traveler confirms with the driver that this is the desired
was and if it goes to the bus stop
2. When boarding the bus the traveler should;
Approach directly until contact with the bus
What is the basic procedure for bus travel continued - ✔✔3. Trail the bus toward the front, Ascend the
stairs, trail the front railing to the pay station, tell the driver the desired stop you want, sit near the bus
driver to help remind the bus driver, ask which side of the street you are being left off at when at your
stop
