Subject: 
Speed Cushion Evaluation 
El Mirage Road –Santa Fe Lane to End Street 
Dear Bryce: 
This letter outlines our analysis, conclusions, and recommendations for speed cushion locations and 
design for El Mirage Road from Santa Fe Lane to End Street. A vicinity map is provided as Figure 1. 
PURPOSE OF STUDY 
The City of El Mirage has requested a study to evaluate if speed cushions are warranted along El 
Mirage Road and, if warranted, to provide an exhibit of recommended locations of speed cushions and 
supplemental signage. 
EXISTING CONDITIONS 
ROADWAY 
El Mirage Road is currently a north-south two-lane undivided roadway with one lane of travel in each 
direction, separated by striping. Both sides of El Mirage Road include sidewalk, curb, on street parking, 
and bike lanes. El Mirage Road begins to the south near Indian School Road and terminates to the 
north at Santa Fe Lane. The speed limit on El Mirage Road is 25 miles per hour (mph). El Mirage Road 
is classified as a major arterial roadway per the City of El Mirage Street Classifications Map. However, 
per the Arizona Department of Transportation (ADOT) Functional Classification Map, this segment of 
El Mirage Road is classified as an Urban Major Collector. The existing roadway geometry and roadway 
environment more closely aligns to a collector roadway. 
TRAFFIC VOLUMES AND SPEED COUNTS 
Bidirectional daily traffic counts and speed counts were collected from Tuesday, April  8, 2025 to 
Thursday, April 10, 2025 on El Mirage Road , south of Santa Fe Lane. A copy of the data is provided 
as an Attachment.

In reviewing the traffic counts, it was found that about 1,950 vehicles per day (vpd) are using El 
Mirage Road on a typical weekday. Total traffic volumes were fairly even in the northbound and 
southbound directions. The summary of average traffic volumes over the 3-day collection period is 
summarized in Table 1.

In reviewing the speed counts along El Mirage Road, it was found that around 78% of all vehicles 
exceeded the 25-mph speed limit. It was found that speeds were slightly higher for the northbound 
direction. A summary of average traffic speeds over the 3-day collection period is summarized in

SPEED CUSHION EVALUATION 
The City of El Mirage Policy for Speed Cushion Installation (revised February 2025) was reviewed to 
determine if speed cushions are currently warranted along the study segment. Speed cushions are 
vertical deflections in the roadway designed to calm traffic along a roadway segment. They are 
designed with spacing to allow emergency vehicles to bypass the speed cushions. Per the policy, the 
following must be met to consider the installation of speed cushions along a public roadway: 
1. The roadway must be classified as a local or collector street. 
2. The current posted speed limit cannot exceed 30 mph. 
3. The 85th percentile of vehicles on the study segment are currently exceeding the speed limit 
by at least 5 miles per hour. 
4. The study segment must have an average daily traffic (ADT) of 400 vpd on a typical weekday. 
Optional: If it is found that drivers are using the street as a “cut-through” route, speed cushions 
can be considered regardless of speed or traffic volume. 
A summary of the criteria and evaluation of the study segment is provided in Table 3.

As shown in Table 3, El Mirage Road is not classified as a collector or local road according to the City 
of El Mirage Street Classifications Map; However, it is classified as a major collector roadway per 
ADOT’s Functional Classification Map and generally aligns more closely to a collector roadway. 
Therefore, El Mirage Road between Santa Fe Lane and End Street currently meets the City’s criteria 
for consideration of speed cushions.  
From this evaluation, it is recommended to install speed cushions along El Mirage Road from Santa 
Fe Lane to End Street.

DESIGN CONSIDERATIONS 
Since the City of El Mirage does not currently have a published criterion for speed cushion design, 
Kimley-Horn researched various local and national standards for the design and location of speed 
cushions. From the research conducted, the following criteria are recommended for this study: 
 
Speed cushions should be placed at a minimum of 150’ from unsignalized intersections, or a 
minimum of 250’ from signalized intersections. 
 
Spacing of speed cushions should be between 250’ and 600’. 
 
Location of speed cushions are preferred on straight and flat segments. If on a curve, there 
should be adequate stopping sight distance upstream of the speed cushion. If on a slope, the 
speed cushion should be placed on or after the crest, and at a maximum grade of 8%. 
 
Speed cushions should avoid manholes, grates, monuments, and other utilities within the 
roadway. 
 
Avoid placing speed cushions close to fire hydrants. 
 
Consider impacts to drainage with the speed cushion location. 
 
Consider installing speed cushions near lighting where available. 
A tabulated list of the recommended criteria has been provided as an Attachment. 
To further evaluate recommended locations of speed cushions for this study segment, the following 
considerations were noted and summarized below: 
 
Several fire hydrants were observed along the east and west side of El Mirage Road. Speed 
cushions should be placed away from fire hydrants to avoid conflict during potential 
emergency operations. 
 
There are several residential driveways along El Mirage Road. Speed cushions should be 
placed appropriately to minimize conflicts with drivers turning into and out of driveways. 
 
The distance between the existing bike lane and the edge of pavement is approximately 12 
feet. As this distance is sufficient for a vehicle to bypass the speed cushions, two 17.25 feet 
exterior speed cushions will be constructed per discussion with the City of El Mirage. 
 
Per discussion with the City of El Mirage, a raised crosswalk will be constructed on the south 
leg of the intersection of El Mirage Road and Santa Fe Lane. The design of the pedestrian 
crosswalk is provided as a separate exhibit.  
 
The recommended location of the traffic calming devices and signage for El Mirage Road is provided 
in Figure 2.

Recommended Design Criteria for Speed Cushions 
Constraint 
Criteria 
Distance from Intersections 
Unsignalized – 150’ Minimum 
Signalized – 250’ Minimum (1) 
Spacing 
250’ Minimum, 600’ Maximum 
Horizontal Design 
Straight Segments Desired 
Curves Permitted (2)  
Vertical Design 
Flat segments Desired 
8% Maximum grade (Installed on or after crest) 
Visibility 
Must be visible to drivers from AASHTO SSD (3) 
(1) 
Assumed that speed limit is 25 mph. If speed limit is 30 mph, use 305’ minimum 
(2) 
Minimum horizontal radius of 300’; must have visibility upstream of speed cushion 
(3) 
Table 3-1 AASHTO A Policy on Geometric Design of Highways and Streets, 2018 
 
Additional Design Considerations: 
• 
Avoid manholes, grates, monuments, and other utilities within roadway 
• 
Avoid locating speed cushions close to fire hydrants 
• 
Consider impacts to drainage with speed cushion location 
• 
Consider installing speed cushions near lighting where available
