2007085\ RPT AZ Seatbelt Use Survey 2007. wpd
INTRODUCTION
This study was commissioned by the Governor’s Office of Highway Safety ( GOHS) as part
of the State and Community Highway Safety Grant Program. The purpose of this effort was to
determine the 2007: 1) seat belt use rate; 2) child restraint use rate; and 3) motorcycle helmet
use rate in the State of Arizona. In addition, this research also collected data on drivers’ use of
hand held cell phones.
The information contained in this report is based on a random probability sample of
signalized and stop signed intersections in Arizona. Observations were made at 127 sites located
in six counties. Each of the site observations lasted for 60 minutes and were conducted during
daytime hours. Where possible, the 2007 observations were made at the same sites utilized in
the prior studies. All of the observations on this project were conducted by professional
interviewers of the Behavior Research Center, Inc. between August 3 and 24, 2007. This timing
followed the GOHS’s Click It or Ticket campaign which ran from May 21 to June 3, 2007. For a
detailed description of the procedures followed during the course of this project, please refer to
the Methodology section of this report.
The Behavior Research Center has presented all of the data germane to the basic
research objectives of this project. However, if the Governor’s Office of Highway Safety requires
additional data retrieval or interpretation, we stand ready to provide such input.

The charts below present 2007 safety restraint use by county. As may be seen, Pima
County records the highest use rates in each category.
• Pima County records the highest rate of front seat occupant seat belt use ( 89.0%) and
Cochise County the lowest ( 75.1%).
• Pima County records the highest rate of child restraint use ( 92.8%) and Yuma County
the lowest ( 63.6%).
• Pima County records the highest rate of motorcycle helmet use ( 100.0%) and Cochise
County the lowest ( 44.4%).
Cell phone use by drivers reaches a high of 18.8 percent in Maricopa County and a low
of 1.9 percent in Yuma County. Maricopa County cell phone use is more than double the use
recorded in any other county.
* Subject to major variation due to limited number of observations

METHODOLOGY
This study utilized a Multi- State Area Probability Sampling ( MSAPS) methodology as
recommended by the National Highway Traffic Administration ( NHTSA) for observational survey
( UNIFORM CRITERIA FOR STATE OBSERVATIONAL SURVEYS OF SEAT BELT USE, 23 CFR PART 1340).
This method is designed to yield statistically valid estimates of not more than +/- five percent of
the following:
1. The current Seat Belt Use ( SBU) rate in the State of Arizona
2. The current Motorcycle Helmet Use ( MHU) rate in the State of Arizona
3. The current Child Restraint Use ( CRU) rate in the State of Arizona
In accordance with NHTSA’s recommendations, all controlled intersections or all road
segments in selected Arizona counties were eligible for sampling in the study. The first stage in
the sampling process was to determine which Arizona counties would be selected as primary
sampling units ( PSUs). This was accomplished based on the vehicle miles of travel in each
county as presented in Table 2. Following GOHS’s direction, six Arizona counties ( Maricopa,
Pima, Coconino, Yavapai, Cochise and Yuma) were selected as PSUs. These six counties were
selected because they contain 86.456 percent of the total state population which meets the
NHTSA requirement that the sampling frame must include at least 85 percent of a state’s
population.

The second stage in the sampling process was to select the number of total observational
sites in the six selected PSUs to achieve the desired level of sampling accuracy. This process
involved the random selection of intersections in the selected PSUs which are controlled by either
signals or stop signs. Per GOHS’s direction, a total of 131 observational sites were selected in
six PSUs. Observations could not be conducted at four of these locations however since they
are located inside Ft. Huachuca Army Base which is a restricted area. The 127 sites included in
this research were the same ones used in the prior surveys.
According to NHTSA recommendations, the VMT of each PSU was used as the weight
for each selected PSU.

Once the observational sites had been determined, BRC conducted a training session for
its field observers. This training involved both classroom and in- field activities. Following training,
the required observations were undertaken according to the specifications detailed in the Field
Observers Instruction Manual presented in the Appendix of this report. Throughout this process
observe- the- observer spot checks were conducted to ensure quality control.
As the data collection segment of this study was being undertaken, the completed
observational forms were turned over to BRC’s in- house computer department for inputting.
Upon completion of data entry, a series of validity and logic checks were run on the data to

SEAT BELT/ CHILD RESTRAINT/ HELMET USE SURVEY - 2007085
FIELD OBSERVER INSTRUCTION MANUAL
BACKGROUND AND PURPOSE
This study is being conducted for the Governor’s Office of Highway Safety to
determine the use of safety belts, child restraints and motorcycle helmets in Arizona and is
being conducted as part of the State and Community Highway Safety Grant Program which
was enacted by the Highway Safety Act of 1966.
During this study curbside observations will be collected at a total of 131 randomly pre-selected
intersections in Arizona, which are controlled by either stop signs or signals. Among
the areas where observations are being conducted are the following six counties which
represent over 85 percent of the State’s population:
Cochise County - Sierra Vista, Benson, Douglas
Coconino County - Flagstaff, Sedona
Maricopa County - Phoenix, Sun City, Peoria, Mesa, Scottsdale,
Glendale, Tempe, Gilbert
Pima County - Tucson, Ajo, Green Valley
Yavapai County - Prescott, Prescott Valley
Yuma County - Yuma
During this study the following information will collected about the passenger vehicles
and motorcycles which are observed at the 131 pre- selected intersections.
Passenger Motor Vehicles - For the purpose of this study passenger motor vehicles
are defined as either: 1) passenger cars, or; 2) other passenger vehicles which include
light pickup trucks, vans and sport utility vehicles. Commercial vehicles such as
delivery trucks and the like are not to be included in any counts during this research.
The information which will be recorded on passenger motor vehicles is: 1) the use of
seat belts by drivers and front seat outboard passengers, and; 2) The use of child
restraint seats by children under five years old either in the front passenger seat or
rear seat.
Motorcycles - When a motorcycle is observed the use of a helmet by the driver and
any passenger will be recorded.

Each of the 131 intersections will be observed for a period of one, pre- selected hour
and all of the observations will be collected during daylight hours when there is sufficient
natural light to permit clear vision into vehicles. The data collection segment of this project will
be conducted between August 3 and August 19, 2007.
FIELD OBSERVER RESPONSIBILITIES
All Field Observers on this project will be thoroughly trained on all the specific activities
they are required to conduct and have the following responsibilities:
1) Attending and successfully completing an initial training session
2) Accurately following the prescribed procedures to complete all necessary
observations for each vehicle
3) Maintaining daily time reports and other administrative documents required by the
survey supervisor
4) Maintaining data collection records in an accurate and complete manner
5) Meeting all established quality control and performance standards
6) Committing their time and effort for the duration of the project
7) Reporting your daily site counts to your supervisor on a daily basis
8) To be safety conscious - safety first
All field observers will report to an assigned supervisor who will work closely with them
throughout the survey. Whenever a field observer is unsure about a procedure or action to be
taken, and adequate instructions cannot be found in this manual, the issue is to be discussed
with the supervisor immediately.
OBSERVER MATERIALS
Each observer will have the following materials for use of this project.
• Two Cover Letters. A copy of a letter which was sent to police and sheriff’s
departments in the communities where the observations are being conducted
and a letter of authorization explaining the study and its purpose to anyone
interested in knowing.

22
2007085\ INTV LTR GOHS. doc
• Daily Observation Packets. An assignment sheet detailing the locations where
the observations will be conducted each day accompanied by Observation
Forms for each selected site and a map for each selected site. The
observation forms contain enough space to record data on 210 vehicles.
Should the number of vehicles observed at a site exceed 210, the observer
shall use a blank observation form which will be provided.
• A safety vest to be worn at all times while conducting observations.
• A wide brimmed hat.
• Bottled water.
• A tote bag.
• A BRC name tag.
• A clipboard.
• Pencils.
FIELD OBSERVATION TECHNIQUES
This section provides a review of basic field observation techniques. All field observers
must be proficient in the application of these techniques.
1) Each site will be observed for a period of one hour.
2) Each traffic observer shall observe the curbside lane of traffic at select
intersections or highway exits controlled by stop signs or signals.
3) If more than one passenger vehicle ( motorcycle) stops, the field observer visually
inspects the second vehicle for use or non- use of shoulder seat belts, helmets,
child restraints. If only one motor vehicle has stopped, then the field observer
observes that vehicle only.
4) After observing the second vehicle and recording the information on the
Observation Form, the field observer shall continue to visually inspect and record
observations for the vehicles that are stopped behind the second vehicle.
Continue observing all vehicles until the signal changes from red to green or there
are no additional vehicles to observe.
5) When the light turns green, the field observer shall return to the intersection for
the next cycle of observation.

6) If for some unexpected reason you are not able to be at your assigned
observation site at the assigned time, you must immediately contact your
supervisor to alert them of the situation. Observe- the- observer spot checks will be
conducted throughout this project so it is very important that you report this
occurrence to your supervisor.
7) If observations cannot be conducted at an assigned site at the assigned time due
to inclement weather, construction, an accident, or other safety problem you must
immediately contact your supervisor to alert them of the situation.
The following items are pre- coded on each Observation Form - site code, specific
intersection corner to be observed, direction of traffic to be observed, and observation
number. The specific date and start time of the observation are not pre- coded and must be
filled in by the field observer - date ( day/ month), time ( 10: 00 AM).
The following information is collected on each vehicle observed:
Vehicle Type
Pass - Passenger car
Other - Other passenger vehicles to include light trucks, vans, and sport utility
vehicles
Motor - Motorcycles
Safety Belt/ Helmet Use
Driver - Yes, using shoulder belt or helmet.
- No, not using shoulder belt or helmet.
Passenger - Yes, using shoulder belt or helmet.
- No, not using shoulder belt or helmet.
The following information is collected on vehicles containing children under five years
old in either the front passenger seat or rear seat. Because of the infrequency of infants and
toddlers in vehicles, the first priority of the observer will be to collect data on these age
groups. For example, if the vehicle under observation has an infant or toddler as well as older
passengers, data on the younger passenger will be collected first. Data for the adult
passengers will be recorded only if there is sufficient time to accurately determine their use of
seat belts.
Child Restraint
Yes, using child restraint seat.
No, not using child restraint seat.
The final piece of information collected is whether or not the vehicle driver is talking on
a cell phone at the time of the observation.
Cell Phone
Yes, using cell phone.
No, not using cell phone.

The purpose of this effort was to determine the 2007: 1) seat belt use rate; 2) child restraint use rate; and 3) motorcycle helmet use rate in the State of Arizona. In addition, this research also collected data on drivers’ use of hand held cell phones. The information contained in this report is based on a random probability sample of signalized and stop signed intersections in Arizona. Observations were made at 127 sites located in six counties. Each of the site observations lasted for 60 minutes and were conducted during daytime hours. Where possible, the 2007 observations were made at the same sites utilized in the prior studies. All of the observations on this project were conducted by professional interviewers of the Behavior Research Center, Inc. between August 3 and 24, 2007.

This method is designed to yield statistically valid estimates of not more than +/- five percent of the following: 1. The current Seat Belt Use ( SBU) rate in the State of Arizona 2. The current Motorcycle Helmet Use ( MHU) rate in the State of Arizona 3. The current Child Restraint Use ( CRU) rate in the State of Arizona In accordance with NHTSA’s recommendations, all controlled intersections or all road segments in selected Arizona counties were eligible for sampling in the study. The first stage in the sampling process was to determine which Arizona counties would be selected as primary sampling units ( PSUs). This was accomplished based on the vehicle miles of travel in each county as presented in Table 2. Following GOHS’s direction, six Arizona counties ( Maricopa, Pima, Coconino, Yavapai, Cochise and Yuma) were selected as PSUs. These six counties were selected because they contain 86.456 percent of the total state population which meets the NHTSA requirement that the sampling frame must include at least 85 percent of a state’s population.

This process involved the random selection of intersections in the selected PSUs which are controlled by either signals or stop signs. Per GOHS’s direction, a total of 131 observational sites were selected in six PSUs. Observations could not be conducted at four of these locations however since they are located inside Ft. Huachuca Army Base which is a restricted area. The 127 sites included in this research were the same ones used in the prior surveys. According to NHTSA recommendations, the VMT of each PSU was used as the weight for each selected PSU.

During this study curbside observations will be collected at a total of 131 randomly pre-selected intersections in Arizona, which are controlled by either stop signs or signals. Among the areas where observations are being conducted are the following six counties which represent over 85 percent of the State’s population: Cochise County - Sierra Vista, Benson, Douglas Coconino County - Flagstaff, Sedona Maricopa County - Phoenix, Sun City, Peoria, Mesa, Scottsdale, Glendale, Tempe, Gilbert Pima County - Tucson, Ajo, Green Valley Yavapai County - Prescott, Prescott Valley Yuma County - Yuma During this study the following information will collected about the passenger vehicles and motorcycles which are observed at the 131 pre- selected intersections. Passenger Motor Vehicles - For the purpose of this study passenger motor vehicles are defined as either: 1) passenger cars, or; 2) other passenger vehicles which include light pickup trucks, vans and sport utility vehicles. Commercial vehicles such as delivery trucks and the like are not to be included in any counts during this research. The information which will be recorded on passenger motor vehicles is: 1) the use of seat belts by drivers and front seat outboard passengers, and; 2) The use of child restraint seats by children under five years old either in the front passenger seat or rear seat. Motorcycles - When a motorcycle is observed the use of a helmet by the driver and any passenger will be recorded. behavior research center, inc.

The data collection segment of this project will be conducted between August 3 and August 19, 2007. FIELD OBSERVER RESPONSIBILITIES All Field Observers on this project will be thoroughly trained on all the specific activities they are required to conduct and have the following responsibilities: 1) Attending and successfully completing an initial training session 2) Accurately following the prescribed procedures to complete all necessary observations for each vehicle 3) Maintaining daily time reports and other administrative documents required by the survey supervisor 4) Maintaining data collection records in an accurate and complete manner 5) Meeting all established quality control and performance standards 6) Committing their time and effort for the duration of the project 7) Reporting your daily site counts to your supervisor on a daily basis 8) To be safety conscious - safety first All field observers will report to an assigned supervisor who will work closely with them throughout the survey. Whenever a field observer is unsure about a procedure or action to be taken, and adequate instructions cannot be found in this manual, the issue is to be discussed with the supervisor immediately. OBSERVER MATERIALS Each observer will have the following materials for use of this project. • Two Cover Letters. A copy of a letter which was sent to police and sheriff’s departments in the communities where the observations are being conducted and a letter of authorization explaining the study and its purpose to anyone interested in knowing. behavior research center, inc.

An assignment sheet detailing the locations where the observations will be conducted each day accompanied by Observation Forms for each selected site and a map for each selected site. The observation forms contain enough space to record data on 210 vehicles. Should the number of vehicles observed at a site exceed 210, the observer shall use a blank observation form which will be provided. • A safety vest to be worn at all times while conducting observations. • A wide brimmed hat. • Bottled water. • A tote bag. • A BRC name tag. • A clipboard. • Pencils. FIELD OBSERVATION TECHNIQUES This section provides a review of basic field observation techniques. All field observers must be proficient in the application of these techniques. 1) Each site will be observed for a period of one hour. 2) Each traffic observer shall observe the curbside lane of traffic at select intersections or highway exits controlled by stop signs or signals. 3) If more than one passenger vehicle ( motorcycle) stops, the field observer visually inspects the second vehicle for use or non- use of shoulder seat belts, helmets, child restraints. If only one motor vehicle has stopped, then the field observer observes that vehicle only. 4) After observing the second vehicle and recording the information on the Observation Form, the field observer shall continue to visually inspect and record observations for the vehicles that are stopped behind the second vehicle. Continue observing all vehicles until the signal changes from red to green or there are no additional vehicles to observe. 5) When the light turns green, the field observer shall return to the intersection for the next cycle of observation. behavior research center, inc.

Observe- the- observer spot checks will be conducted throughout this project so it is very important that you report this occurrence to your supervisor. 7) If observations cannot be conducted at an assigned site at the assigned time due to inclement weather, construction, an accident, or other safety problem you must immediately contact your supervisor to alert them of the situation. The following items are pre- coded on each Observation Form - site code, specific intersection corner to be observed, direction of traffic to be observed, and observation number. The specific date and start time of the observation are not pre- coded and must be filled in by the field observer - date ( day/ month), time ( 10: 00 AM). The following information is collected on each vehicle observed: Vehicle Type Pass - Passenger car Other - Other passenger vehicles to include light trucks, vans, and sport utility vehicles Motor - Motorcycles Safety Belt/ Helmet Use Driver - Yes, using shoulder belt or helmet. - No, not using shoulder belt or helmet. Passenger - Yes, using shoulder belt or helmet. - No, not using shoulder belt or helmet. The following information is collected on vehicles containing children under five years old in either the front passenger seat or rear seat. Because of the infrequency of infants and toddlers in vehicles, the first priority of the observer will be to collect data on these age groups. For example, if the vehicle under observation has an infant or toddler as well as older passengers, data on the younger passenger will be collected first. Data for the adult passengers will be recorded only if there is sufficient time to accurately determine their use of seat belts. Child Restraint Yes, using child restraint seat. No, not using child restraint seat. The final piece of information collected is whether or not the vehicle driver is talking on a cell phone at the time of the observation. Cell Phone Yes, using cell phone. No, not using cell phone. 2007085\ 24 INTV LTR GOHS. doc SAMPLE FORM SEAT BELT/ CHILD RESTRAINT/ HELMET USE SURVEY – 2007085 SITE CODE: 040 – Maricopa/ Phoenix DATE: TIME: INTERSECTION: VAN BUREN STREET AND 2 ND STREET ( NORTHWEST - SOUTH) — SAFETY BELT/ HELMET — CHILD CELL OBSERVATION VEHICLE TYPE DRIVER PASSENGER RESTRAINT PHONE NO.
