CHECKLIST: Skills and Concepts

to Assess / Cross Streets with No Traffic Control

Background information

1.Visual condition ______

2.Challenges and accommodative skills for glancing:

Situations which are challenging for student to glance to detect approaching vehicles:

___ seeing cars at a distance (e.g. reduced acuity, central scotoma, etc.)

___ seeing a single car two car-lengths away in nearest lane (e.g. reduced visual field)

___ other:______

___ there is no challenging situation for glancing.

Accommodative skills required for glancing to see approaching vehicles reliably:

___ eccentric viewing

___ holding glance long enough to detect movement of vehicles

___ scanning slowly enough to see details

___ visually finding street and scanning along it

___ manipulating telescopic aid quickly

___ other:______

___ no accommodative skills are required for glancing efficiently.

Field testing/teaching

UNDERSTANDING CROSSING TIME:

____ Student can estimate width of unfamiliar streets (up to 5-6 lanes)

____ Student has intuitiveunderstanding of own crossing time for:

____ 2 lanes____ 3 lanes____ 4 lanes____ 5 lanes

SITUATIONS OF UNCERTAINTY / CONFIDENCE:

HEARING(see note**):

____ Student can recognize Situations of Uncertainty using hearing

(checklist “Teaching Students to Recognize Situations of Uncertainty”

using hearing)

At Situationsof CONFIDENCE using hearing:

student can

___ determine when it is quiet enough to know it is clear.

___ understand the effect of masking sounds on ability to hear traffic.

VISION(see note**):

Student can

____ recognize Situations of Uncertainty using vision

(checklist“Teaching Students to Recognize Situations of Uncertainty” using vision)

____ recognize effect of visual conditions (night, glare, etc.) on ability to see traffic

____ reliably detect vehicles by glancing.

____ determinegaps in approaching vehicles (see checklist)accurately

in a variety of visual conditions, including at night.

____ reliably determine gaps in approaching vehicles by glancing.

ASSESSING RISK AND USING ALTERNATIVES:

____In Situations ofUncertainty, student can assess risk of crossing

and determine if risk is acceptable.

____ Student understands alternatives (see checklist).

USING VISION / HEARING:

____ Student can determine whether hearing or vision is better ineach situation.

Student has experienced at least one situation where

vision is more efficient than hearing to detect traffic;
hearing is more efficient than vision.

Chart is filled with information from checklists of situations on following page:

Situation # / Traffic was detected
best with: / traffic detected well enough to know clear when quiet with:
Hearing / Vision / Hearing / Vision / Neither
Situation 1
Situation 2
Situation 3
Situation 4
Situation 5
Situation 6
Situation 7

**Note: It usually does not matter if the assessments are done first with hearing and then with vision, or vice versa.

You could assess both hearing and vision for students in a given situation by documenting when theyfirst hear AND first see each vehicle coming, if it is quiet when they first hear it. But because students may be able to see a vehicle sooner if they hear it first, and may be able to hear a vehicle sooner if they see it first,if the purpose is to assess hearing only, the student’s vision should be occluded and to assess vision only, the hearing should be occluded with noise and/or earplugs.

Situation #___: Name of crossing: ______date:______

Steady conditions (weather, blockage, lighting, wet pavement, steady masking sound, etc.):

______

When student used HEARING, TMAD showed that traffic was detected reliably enough

to know it was clear to cross whenever there are no extraneous sounds present:

___ yes (knows it’s clear when there is no extraneous noise and no traffic can be heard)

___ no (can’t tell if it’s clear to cross, even with no extraneous noises or traffic sound)

When student used VISION, TMAD showed that traffic could reliably be seen

far enough to know it was clear to cross whenever no vehicles could be seen:

___ yes (knows it’s clear when no approaching vehicles visible in that lighting condition)

___ no (can’t tell if it’s clear to cross, even if student can’t see any vehicles)

Traffic in this situation best detected with

____ VISION

____ HEARING
