EXECUTIVE SUMMARY
The City of Phoenix is currently in the process of developing a Comprehensive Roadway Safety Action Plan,
which will further shape the City’s planning efforts in roadway safety. This project involves a review of
current safety trends, existing programs and processes, and public/stakeholder involvement to create a
vision and plan for the future. This memorandum is intended to provide a preliminary overview of historical
crash trends within the City of Phoenix within the past five years. In later stages of this project, a dynamic
crash dashboard will be developed to provide enhanced abilities in data analytics and reporting.
In the initial stages of this project, crash queries were obtained through the Maricopa Association of
Governments (MAG) software tool for crash analysis, the Regional Transportation Safety Information
Management System (RTSIMS). This report uses existing tools to conduct a safety analysis of the past five
years, and compares trends to regional and statewide data. The following key findings are based on a
review of RTSIMS crash data from 2015 to 2019:
•
An annual average 30,376 crashes per year were reported during the five year study period. This
equates to 83 crashes per day.
•
Crashes on arterial and local roadways in the City of Phoenix increased by a rate of about 4.4% per
year. This trend suggests that the crash frequency increased at a higher rate than the City’s
population, which in the same period grew 1.5% per year, on average.
•
Most crashes result in no injury (70%), approximately one-quarter result in possible or minor injury
(27%), 2.6% result in serious injury, and 0.6% result in fatal injury. This equates to two serious injury
crashes occurring each day, and one fatal crash occurring every other day.
•
The percentage of fatal and serious injury crashes has remained generally consistent over the past
five years; however the percentage of no injury crashes has steadily increased over time.
•
For all crash severities, rear end crashes were the most common collision manner, followed by left-
turn crashes. These two crash types account for about half of all crashes.
•
For fatal and serious injury crashes, the “Other” collision manner was reported most frequent
(25%), which is commonly selected for crashes involving pedestrians and bicyclists. Other frequent
crash types for fatal and serious injury crashes were left-turn (23%) and angle (21%).
•
Crashes involving unrestrained drivers (i.e, lack of seatbelt or helmet use) have reduced in
frequency.
•
Due to lack of protection on impact, pedestrians and bicyclists (vulnerable users) are more
frequently seriously injured when involved in motor vehicle crashes. In the City of Phoenix, crashes
involving bicyclists and pedestrians represent nearly half (48%) of all fatal crashes.
•
A greater share of pedestrian crashes is occurring in Phoenix compared to other agencies within
the MAG Region. Phoenix represents 36% of Maricopa County’s population and about 43% of the
County’s local and arterial road crashes; however, 63% of County crashes involving pedestrians
occurred on City of Phoenix’s local and arterial roads.
•
Bicyclist crashes are occurring at a greater rate in Phoenix than in other agencies within the MAG
Region. About 43% of all crashes involving bicyclists in Maricopa County occurred on City of
Phoenix’s local and arterial roads.
•
For all crash severities, the majority of crashes occur during daylight hours (71%), with the
remaining 29% of crashes occurring during dawn, dusk, or dark conditions.
•
A correlation exists between injury severity and lighting condition; fatal and serious injury crashes
occurred more frequently during dawn, dusk, and dark conditions (45%) compared to daylight
conditions (55%).

MAG RTSIMS tool provided the ability to retrieve data quickly for numerous Citywide statistics. During the
analysis process, several discrepancies were identified when comparing to past Phoenix data, which is
common when comparing different datasets. The City of Phoenix conducts a robust data scrubbing process
each year, which confirms crashes exist within the City of Phoenix boundaries, omits freeway crashes, and
reviews characteristics of crashes in detail to correct the manner of collision if originally mis-coded. The
RTSIMS crash data is not scrubbed, and comes directly from ADOT ACIS. These differences, along with
variations in the querying process, are acknowledged as part of this report. This data contained in this
report is intended to provide preliminary information; later stages of this project will modernize the existing
City of Phoenix crash analysis process to improve and enhance data analytics and visualization.

INTRODUCTION
The City of Phoenix is currently in the process of developing a Comprehensive Roadway Safety Action Plan,
which will further shape the City’s planning efforts in roadway safety. This project involves a review of
current safety trends, existing programs and processes, and public/stakeholder involvement to create a
vision and plan for the future. This memorandum is intended to provide a preliminary overview of historical
crash trends within the City of Phoenix within the past five years. Through the development of the project,
a dynamic crash dashboard will be developed to provide enhanced abilities in data analytics and reporting.
In the initial stages of the project, crash queries were obtained through the Maricopa Association of
Governments (MAG) software tool for crash analysis, the Regional Transportation Safety Information
Management System (RTSIMS).
The City of Phoenix prepares comprehensive collision summary reports each year, documenting the past
year of motor vehicle, pedestrian, and bicycle-related crashes. This report uses existing tools (RTSIMS) to
conduct a supplementary safety analysis of the past five years, and compare trends to regional and
statewide data.
Crash data within the City of Phoenix was obtained for the past five years through the RTSIMS tool, from
January 1, 2015, to December 31, 2019. At the time of the analysis, 2020 crash data was not available. The
RTSIMS platform compiles historical crash data from the Arizona Crash Information System (ACIS) crash
database maintained by the Arizona Department of Transportation (ADOT). The RTSIMS data excludes
freeways, highways, and ramps; only arterial, collector, and local roadways are included. RTSIMS refers to
this group as “Arterial and Local Roads”. This naming refers to roadway classification and does not imply
roadway ownership. The results of traffic safety data queries may differ slightly based on data source,
filtering assumptions, modifications to raw data, and/or query techniques. The RTSIMS safety review is
intended to identify trends and inform decisions to support roadway safety.
Due to the limited sample size of fatal crashes, fatal and serious injury crashes were combined to analyze
trends in critical crashes. Unlike less severe crashes, the most common collision manner for fatal and
serious injury crashes is “Other”, which primarily represents bicyclist and pedestrian crashes, followed by
left-turn and angle crashes. It was also observed that KA crashes are overrepresented in non-daylight
conditions.
According to the US Census Bureau Annual Population Estimates (Figure 1), the City of Phoenix’s
population has grown about 6% during the five years under study, from 2015 to 2019. In 2020, the City of
Phoenix’s residents represented 23% of Arizona’s population and 36% of Maricopa County’s Population.

GENERAL TRENDS
Since 2015, the total number of crashes within the City of Phoenix has been steadily increasing, with a total
of 31,827 crashes occurring in 2019 on the City’s local and arterial roadway network. Figure 2 shows the
number of crashes by injury severity for each year in the analysis period. The percentage of fatal crashes
has stayed relatively constant, ranging from 0.5% to 0.7% of all crashes. The percentage of serious injury
crashes varied between 2.1% and 3.2% of fatal crashes. The combined minor injury and possible injury
ranged has steadily decreased over the past five years, from 30.7% (2015) to 23.8% (2019). The share of no
injury crashes has increased over the past five years, from 66.0% (2015) to 73.6% (2019). This data suggests
a slight downward trend in the severity of crashes.
Figure 3 shows the number of fatal and serious injury crashes from 2015 to 2019, which combined are
trending towards fewer crashes since 2016.

Crash data from 2020 was not available through RTSIMS at the time of this report. Based on a preliminary
review of 2020 crash data, total number of crashes decreased by about 20% from 2019 crashes, which is
presumed to be related to lower vehicle miles travelled as a result of the COVID-19 pandemic. The share of
fatal and incapacitating injury crashes remained generally consistent with the previous five years; however,
the share of no injury crashes followed the same positive trend (increasing from 73.6% in 2019 to 74.2% in
2020). Preliminary 2021 crash data, obtained through the Phoenix Police Department Vehicle Crimes Unit
(VCU), indicate that there were 114 fatal crashes during the first six months of 2021.
Table 1 shows the distribution of crashes on City of Phoenix local and arterial roads by collision manner for
the past five years. The most frequently-reported crash types were rear-end crashes (29% of all reported
crashes) followed by left-turn crashes (23% of all crashes). Together, rear-end and left-turn crashes
represent about half of all crashes.

Note: The City of Phoenix uses a data scrubbing process to improve consistency of coding for collision manner. For
example, the City of Phoenix defines left-turn crashes as involving vehicles originally traveling in the opposing
(parallel) direction. If a crash involves a left-turning movement, but the vehicles originate in perpendicular paths,
the collision is defined as an angle crash. The results of Table 1 were summarized using RTSIMS data, which does
not involve the City of Phoenix scrubbing process. Therefore, these results vary from City of Phoenix scrubbed data,
which identifies that the leading manner of collision is rear-end crashes, followed by angle crashes, then left-turn
crashes.
Table 2 shows the number of pedestrian and bicyclist crashes per year, as well as the injury severity.
Pedestrian crashes have been slowly increasing over the past five years, while bicyclist crashes have been
decreasing. An initial review of 2020 data indicates consistency with these trends.
Over the five-year period, pedestrians were involved in an average of 86 fatal crashes per year, and bicyclists
were involved in an average of 8 fatal crashes per year. Combined, crashes involving pedestrians and
bicyclists represent nearly half (48.6%) of all fatal crashes. Preliminary 2021 crash data, obtained through
the Phoenix Police Department VCU, indicate that there a total of 114 fatal crashes reported in the first six
months of 2021, 52 (45.6%) of which involved pedestrians, and 4 (3.5%) of which involved bicyclists.

CRASHES BY MONTH
Figure 4 and Figure 5 show the frequency of crashes in the City of Phoenix (arterial and local roads) by
month. The month-to-month trends are consistent between all crashes, serious injury crashes, and fatal
crashes. March registered the highest number of crashes, including fatal and injury crashes. The month with
the fewest reported crashes was July, which correlates with lower summer traffic volumes. Lower traffic
volumes in June and July are often associated with school breaks, seasonal resident travel, lower
pedestrian and bicyclist activity, and lower traffic volumes in general due to the high temperatures.

Figure 9: Crash Location Relative to Junctions, by Year
Figure 10 shows the injury severity between the three location types. In general, crashes are slightly more
severe at intersections and interchanges, compared to segment collisions, which correlates with the
greater frequency and types of collisions/conflict points possible.
Figure 10: Injury Severity of Intersection/Interchange-Related Crashes
The collision manner of intersection and interchange crashes is shown in Figure 11. The three most
common crash types at intersections are left-turns, rear-ends, and angle crashes, respectively.

To rank the intersections based on a holistic safety analysis, the MAG’s network screening methodology
was used to classify the City of Phoenix’s intersections per their safety score. The scoring methodology
combines three safety attributes on the intersection, including crash frequency, crash severity, and crash
type. The three factors are weighted together for the final Intersection Safety Score, with crash severity as
50%, crash frequency as 25%, and crash type as 50% of the weighting. Table 3 and Figure 12 show the Top
20 intersections with the highest Intersection Safety Score within the City of Phoenix.
The intersections with the greatest crash risk exist at 1) 75th Avenue and Indian School Road, 2) 67th Avenue
and Indian School Road, and 3) 67th Avenue and McDowell Road. Formal Road Safety Assessments (RSA)
have been conducted at 10 of the Top 20 high crash risk intersections.

BEHAVIOR CHARACTERISTICS
In the period of 2015 to 2019, alcohol and drug-impaired drivers were responsible for 7,487 crashes, which
represents 5% of all crashes on local and arterial roads in the City of Phoenix. However, of all 4,962 fatal and
serious injury crashes, 1,117 (22%) were associated with impaired drivers. Figure 13 shows the distribution
of crashes involving impaired drivers (alcohol, drugs) by the hour of the day. Unlike the total number of
crashes that show two distinct peaks of crashes over the AM and PM traffic peaks (Figure 8), crashes
involving impaired drivers are mostly concentrated during the late hours of the night (7 PM to 3 AM).
Figure 13: Number of Crashes Involving Impaired Drivers, by Hour
During the five years analyzed in this report, the total number of crashes involving unrestrained drivers
show a steady decline. From 2015 to 2019, unrestrained driver crashes have reduced by approximately 20%.
Figure 14 shows the injury severity of such crashes over the years. On average, about 7% of unrestrained
driver crashes are fatal crashes, which is a significantly larger share compared to all crashes.

Figure 15 shows the severity associated with speed-related crashes across the study period. While on
average about 70% of speed-related crashes result in no injury, close to 2% of such crashes result in serious
injury or fatality.
Figure 15: Speed-Related Collisions, by Year and Injury Severity
TRENDS BY PERSON TYPE
This sub-section of the report further explores crashes involving pedestrians, bicyclists, older drivers, and
younger drivers. The analysis period is from 2015 to 2019. Pedestrian and bicyclists are considered to be
vulnerable roadway users; as there is little to no protection in collisions with motor vehicles. Crashes
involving pedestrians and bicyclists are more likely to result in critical injuries.
PEDESTRIANS
Figure 16 shows the injury severity of crashes involving pedestrians on the City of Phoenix’s local and
arterial roads from 2015 to 2019. While most (70%) motor-vehicle crashes result in no injury, that is not the
case for crashes that involve pedestrians. Rather, 11% of crashes involving pedestrians were fatal and 22%
resulted in serious injuries. In the five studied years, the number of crashes involving pedestrians trended
upward, with 2019 crashes representing a 33% increase from 2015.

Figure 17 shows the collision manner for the crashes involving pedestrians. As most of the collision manner
categories developed for the Arizona Crash Report form are oriented towards motor vehicles, the most
common collision manner reported on pedestrian crashes was “Other”, which is often selected by the
responding police officer for crashes involving pedestrians or bicyclists.

BICYCLISTS
Similar to pedestrian crashes, crashes involving bicyclists registered higher rates of fatalities and serious
injuries, with virtually no crashes being reported as property damage only (Figure 20). During the past five
years, the number of bicycle-related crashes have trended downward. From 2015 to 2019, the number of
crashes involving bicyclists has reduced by 32%.
Figure 20: Injury Severity for Crashes Involving Bicyclists, by Year
Figure 21 shows the collision manner for crashes involving bicyclists. As it was observed for pedestrian
crashes, the most common collision manner was “Other”. However, for crashes involving bicyclists, a
significant share of crashes was a result of angle crashes.

TRENDS OF FATAL AND SERIOUS INJURY CRASHES
This analysis uses the KABCO scale of crash severity, where “K” denotes a fatal crash, “A” is a serious injury
crash, “B” is a minor injury crash, “C” is a possible injury crash, and “O” is a property damage-only crash.
This subsection of the report further details crashes that resulted in at least one serious injury or fatality,
and this sub-set of crashes are referred to as “KA” or “KSI” Crashes. A review of critical crashes can identify
key trends for further investigation. Compared to reviewing fatal crashes only, reviewing the combination
of fatal and serious injury crashes provides a greater sample size and reduces the volatility between years.
KA CRASHES BY COLLISION MANNER
Figure 32 compares the collision manner of KA crashes with crashes that resulted in no injury, possible
injury, or minor injuries (BCO crashes). The most common collision manner of BCO crashes is rear-end
crashes, while the most common collision manner for KA crashes is “Other”. It is important here to note
that the “Other” category is often used to describe the collision manner of crashes involving pedestrians
(Figure 17) and crashes involving bicyclists (Figure 21). The second and third most common collision
manners for KA crashes are left-turn and angle crashes, respectively.

KA CRASHES BY TIME OF DAY
When analyzing all crashes in the City of
Phoenix’s local and arterial roads together,
only 26% of them occur in dark conditions
(Figure 7). However, 40% of KA crashes were
reported to have occurred in dark conditions.
Figure 35 shows that KA crashes are
overrepresented in non-daylight conditions.

Figure 37: Number of Fatal and Serious Injuries Crashes, by Relation to the Intersection
When comparing the collision manner on intersection-related serious crashes (Figure 38) and all crashes
(Figure 11), it can be seen that while rear-end crashes are the second most common intersection-related
crashes, they represent less than 10% of serious crashes. The most common collision manner of
intersection-related KA crashes were left-turn and angle crashes.

COMPARISON TO STATEWIDE AND REGIONAL SAFETY TRENDS
Nationwide summaries of all crashes are available from the National Highway Traffic Safety Administration
(NHTSA) Annual Report Tables. NHTSA reports on a yearly basis crash summaries by diverse aspects, such
as injury severity, first harmful event, and collision manner.
The Arizona Strategic Traffic Safety Plan (ADOT STSP), published in October 2019, summarizes crash data
from the ACIS database from 2009 to 2018. The crash statistics in the ADOT STSP are primarily reported at
the person-level, which varies from the RTSIMS reporting, which is primarily at the crash-level. Furthermore,
the ADOT STSP does not make any distinction between local roads and freeways while RTSIMS reports (for
the purpose of this summary) focus on local and arterial roads only. For the purposes of this comparison,
statewide data at the crash-level was retrieved from the ACIS database.
From 2015 to 2018, 43% of the MAG Region’s local and arterial road collisions were registered in the City of
Phoenix (Figure 40). In terms of population, City of Phoenix residents represent 36% of Maricopa County’s
population. Figure 41 compares the injury severity of collisions reported in the state of Arizona, MAG Region
local and arterial roads, and City of Phoenix local and arterial roads. The results indicate that the fatality
rate (at the crash level) is rather similar among the geographies; from 2015 to 2018, 0.6% of all crashes
reported on local and arterial roads were fatal crashes, both in the City of Phoenix and in the MAG Region,
at the state level, about 0.7% of all reported crashes were fatal.

Figure 41: Crash Severity Comparison of State of Arizona, MAG Region, and City of Phoenix (2015-2018)
In the same period, fatal crashes in the City of Phoenix corresponded to 46.6% of the MAG Region’s fatal
crashes. Figure 42 shows a similar comparison for fatal crashes registered on the two areas, in addition to
the total crashes in the state of Arizona. Figure 43 shows the number of fatalities (person-level) registered
per year in the state of Arizona and the City of Phoenix. During the five years under study, fatalities on the
City of Phoenix’s local and arterial roads represented 21% of all Arizona’s traffic-related fatalities. This
percentage is slightly lower than the share of Arizona residents living in Phoenix in the same period (23%).
*Note: MAG data was sourced from the MAG Strategic Transportation Safety Plan, which analyzed data from 2009 to

PEDESTRIANS
A large share of traffic fatalities involve pedestrians. Figure 45 shows that the State of Arizona was above
the national average, with pedestrians accounting for approximately 22% of 2019 fatalities. In the City of
Phoenix, the share of fatalities that is represented by pedestrians grew from 37% in 2015 to 44% in 2019

Although the MAG STSP data does not exclude freeway crashes, an analysis of the data found that 98% of
total pedestrian crashes in the 10-year studied period (2009-2018) occurred off-freeway, on the local and
arterial roadway network. The analysis also found that the same percentage was true for bicycle-related
crashes. Therefore; the MAG STSP and RTSIMS datasets are reasonably similar for comparison purposes.
As shown in Figure 47, The percentage of pedestrian-related crashes was found to be 1.1% in all United
States, 1.1% in the State of Arizona, 1.7% in the MAG region, and 2.5% in the City of Phoenix.
Phoenix represents 36% of the County’s population and about 43% of local and arterial road crashes;
however, 63% of Maricopa County’s pedestrian-related crashes occurred in the City of Phoenix’s local and
arterial roads.
*Note: MAG data was sourced from the MAG Strategic Transportation Safety Plan, which analyzed data from 2009 to 2018. Data from
2019 was not available for comparison.
Figure 47: Pedestrian Crashes per Year, Comparison across Geographies
In terms of injury severity, the distribution of pedestrian-related crashes is very similar in the MAG Region
and the City of Phoenix (Figure 48). The majority of crashes (63%) of both datasets result in possible or
minor injury, while nearly one-quarter (22-23%) result in serious injury, and about 12% result in fatal injury.
Only a very small portion of pedestrian-related crashes result in no injuries (2-3%).

BICYCLISTS
As shown in Figure 49, the percentage of crashes involving bicyclists was similar between the two areas,
with an average of 1.5% of total crashes in the MAG Region and 1.5% in the City of Phoenix. The injury
severity distribution of bicyclist-related crashes is also similar between the two areas, as shown in Figure
50. The majority of crashes (78-79%) of both datasets result in possible or minor injury, 13% result in serious
injury, and 2% result in fatal injury. About 6-7% of bicyclist-related crashes resulted in no injuries.

OLDER DRIVERS (65 and older)
Other vulnerable user groups were also analyzed, including older drivers and younger drivers. Figure 51
compares the number of crashes involving older drivers on all roads of the MAG Region and City of Phoenix’s
local and arterial roads. Approximately 28% of the older driver crashes in the MAG Region were registered
on City of Phoenix’s local and arterial roads.
*Note: 2019 data was not available for the MAG Region per its Strategic Transportation Safety Plan.
Figure 51: Older Driver Crashes per Year, MAG Region, and City of Phoenix
Figure 52 shows a breakdown by injury severity for crashes on local and arterial roads involving older
drivers in the period of 2015-2018. Compared to crashes involving all age groups, the percentage of fatal
and serious injury crashes remained the same, with a slight shift from no injury to possible and minor injury
crashes. The trends of older drivers are quite similar between the MAG Region and City of Phoenix.

CONCLUSION
Crash queries were obtained through the Maricopa Association of Governments (MAG) software tool for
crash analysis, the Regional Transportation Safety Information Management System (RTSIMS). This report
used existing tools to conduct a safety analysis of the past five years, and compared trends to regional and
statewide data. The following key findings are based on a review of RTSIMS crash data from 2015 to 2019:
•
An annual average 30,376 crashes per year were reported during the five year study period. This
equates to 83 crashes per day.
•
Crashes on arterial and local roadways in the City of Phoenix increased by a rate of about 4.4% per
year. This trend suggests that the crash frequency increased at a higher rate than the City’s
population, which in the same period grew 1.5% per year, on average.
•
Most crashes result in no injury (70%), approximately one-quarter result in possible or minor injury
(27%), 2.6% result in serious injury, and 0.6% result in fatal injury. This equates to two serious injury
crashes occurring each day, and one fatal crash occurring every other day.
•
The percentage of fatal and serious injury crashes has remained generally consistent over the past
five years; however the percentage of no injury crashes has steadily increased over time.
•
Rear end crashes were the most common collision manner, followed by left-turn crashes. These
two crash types account for about half of all crashes.
•
For fatal and serious injury crashes, the “Other” collision manner was reported most frequent
(25%), which is commonly selected for crashes involving pedestrians and bicyclists. Other frequent
crash types for fatal and serious injury crashes were left-turn (23%) and angle (21%).
•
Crashes involving unrestrained drivers (i.e, lack of seatbelt, helmet use) have reduced in frequency.
•
Due to lack of protection on impact, pedestrians and bicyclists (vulnerable users) are more
frequently seriously injured when involved in motor vehicle crashes. In the City of Phoenix, crashes
involving bicyclists and pedestrians represent nearly half (48%) of all fatal crashes.
•
A greater share of pedestrian crashes is occurring in Phoenix compared to other agencies within
the MAG Region. Phoenix represents 36% of Maricopa County’s population and about 43% of the
County’s local and arterial road crashes; however, 63% of County crashes involving pedestrians
occurred on City of Phoenix’s local and arterial roads.
•
Bicyclist crashes are occurring at a greater rate in Phoenix than in other agencies within the MAG
Region. About 43% of all crashes involving bicyclists in Maricopa County occurred on City of
Phoenix’s local and arterial roads.
•
For all crash severities, the majority of crashes occur during daylight hours (71%), with the
remaining 29% of crashes occurring during dawn, dusk, or dark conditions.
•
A correlation exists between injury severity and lighting condition; fatal and serious injury crashes
occurred more frequently during dawn, dusk, and dark conditions (45%) compared to daylight
conditions (55%).
The MAG RTSIMS tool provided the ability to retrieve data quickly for numerous Citywide statistics. During
the analysis process, several discrepancies were identified when comparing to past Phoenix data, which is
common when comparing different datasets. The City of Phoenix conducts a robust data scrubbing process
each year, which confirms crashes exist within the City of Phoenix boundaries, omits freeway crashes, and
reviews characteristics of crashes in detail to correct the manner of collision if originally mis-coded. The
RTSIMS crash data is not scrubbed, and comes directly from ADOT ACIS. These differences, along with
variations in the querying process, are acknowledged as part of this report. This data contained in this
RTSIMS Safety Review
Road Safety Action Plan | Page 40
report is intended to provide preliminary information; later stages of this project will modernize the existing
City of Phoenix crash analysis process to improve and enhance data analytics and visualization.
