Self-Study Guide: Preparing Visually Impaired Students to Assess and Cross Streets with No Traffic Control
Essential questions:
1. What assumption about crossings with no traffic control is no longer true? What evidence do we have for this?
2. What is the consensus of the O&M profession regarding the responsibility of O&M specialists for teaching their students about crossings with no traffic control?
What documentation shows that there is consensus about this responsibility?
3. Can we rely on crossing strategies such as starting to cross with a car that was waiting at the stop sign on the parallel street beside us?

Page 1: "Situations of Uncertainty for Gap Judgment"
Essential questions:
1. Are there situations today in which we can not be confident it is clear to cross even though it is quiet and we hear no vehicles approaching?
Are there any situations today where we can be confident that it is clear to cross whenever it is quiet?
[Can't find the answers? Look here and here and here]
2. Are there any rules or guidelines for figuring out whether you are in a situation of uncertainty for gap judgment, other than carefully observing how well you can hear or see the vehicles?
That is, are there any features of intersections that we know can predict whether or not there is a situation of uncertainty for gap judgment?
3. What are the implications of this information for teaching people to cross streets where there is no traffic signal or stop sign?

Essential questions:
1. In the Procedure to Develop Judgment of the Detection of Traffic, what should you do to help ensure that students can recognize situations of uncertainty for gap judgment?
Which timing method of assessment is used in this procedure?
2. What can be done to help students understand the effect of noise or masking sounds on their ability to hear approaching traffic?
3.
Which timing method of assessment helps students learn to recognize
- when they cannot hear / see the vehicles far enough away to know when it's clear to cross?
- how fast and how far the approaching vehicles are?
- when they have enough time to cross even though they can hear or see vehicles approaching?
- the effect of masking sounds on their ability to hear the cars?
4. What issue is of concern when using the Timing Method for Assessing Detection of Vehicles?
5. What are the specific steps for using the TMAD and TMASD?
6. When using the Timing Method for Assessing Speed and Distance of Vehicles to develop judgment of gaps for crossing, what factors should be included when determining the length of time for "X"?
