TRAFFIC ENGINEERING STUDY
INTRODUCTION
The availability of roadway network in our communities has provided several positive
qualities that have contributed to high standard of living. At the same time, however, several
problems related to the roadway network have developed. These problems include roadway -
related accidents, speeding, parking difficulties, congestion, and delay. To reduce the negative
impact of roadways, it is necessary to collect adequate information that describes the extent of
the problems and identifies their locations. Such information is usually collected by
organizing and conducting relevant traffic surveys and studies.
PURPOSE
The purpose of this traffic study is to evaluate the impact of the traffic circle at the
intersection of Keithwood Drive at Adella Court, and determine if a multi -way stop sign
is needed and improvements to the existing traffic conditions. This report contains
conclusions and recommendations necessary to mitigate existing and potential future
problems at the intersection of Keithwood Drive at Adella Court. Figure 1 shows the
study location.
STUDY METHODOLOGY:
The traffic engineering evaluation at the intersection of Keithwood Drive at Adella Court
were established through the following sequence of activities:
• A field reconnaissance of the intersection and immediate vicinity was conducted for
the purposes of gaining insight into existing travel patterns and characteristics.
• Traffic safety evaluation along the immediate vicinity of the intersection was
conducted.
• 24-hour approach counts were collected at the intersection of Keithwood Drive at
Adella Court.
EXISTING CONDITIONS
Roadway. Keithwood Drive and Adella Court are two lane roadway that provides direct

access single family homes within the immediate vicinity of the study area. A mini traffic
circle currently exist at the intersection of Keithwood and Adella Court. The eastbound
terminus of Adella Court terminates as a cul-de-sac, whereas the westbound terminus
forms a "T" type intersection with Keithwood Drive. A stop sign controls the westbound
approach of Adella Court at Keithwood and yield signs on the north and southbound
approaches of Keithwood Drive.
Traffic Data and Observations. 24-hour traffic data counts were collected on August 21,
2006. A summary of the traffic data are attached in the Appendix of this report. An in-
depth field observations were conducted on June 28 and August 15. 2006 during the AM
and PM peak hour. Five pedestrian traffic were observed crossing the intersection during
field investigation.
Accident Data: Accident records for the study roadway were verified for incidents that
have occurred in the recent 12-month period on file. No accident was recorded during
this period.
Traffic Safety Investigation:
An in-depth field review was conducted at the intersection of Keithwood Drive at Adella.
This review involves an inspection of the physical condition of the roadway and an
observation of traffic operations. Information obtained from this field review in
conjunction with traffic data collected by TDAI was used to analyze any potential
existence of physical deficiencies. Tire marks were observed at the curb within the traffic
circle. This could be associated with drivers inability to maneuver safely at the traffic
circle due to inadequate lane width or turning radii at the traffic circle, speeding, drivers
inattention and failure to observe warning signs.

MULTI -WAY STOP ANALYSIS
Manual on uniform traffic Control Devices (Millennium Edition)
Section 2B-07 Multi -way Stop Applications
The Multi -way Stop" installation is useful as a safety measure at some locations. It
should ordinarily be used only where the volume of traffic on the intersecting roads is
approximately equal. A traffic control signal is more satisfactory for an intersection with
a heavy volume of traffic.
The following criteria should be considered in the engineering study for a multi -way
STOP sign installation:
A. Where traffic control signals are justified, the multi -way stop is an interim
measure that can be installed quickly to control traffic while arrangements are
being made for the installation of the traffic control signal.
B. A crash problem, as indicated by five or more reported crashes in a 12-month
period that are susceptible to correction by a multi -way stop installation. Such
crashes include right -and -left -turn collisions as well as right-angle collisions.
C. Minimum traffic volumes:
(1) The vehicular volume entering the intersection from the major street
approaches (total of both approaches) average at least 300 vehicles per
hour for any 8 hours of any average day. and
(2) The combined vehicular, pedestrian, and bicycle volume entering the
intersection from the minor street approaches (total of both approaches)
average at least 200 units per hour for the same 8 hours, with an average
delay to minor -street vehicular traffic of at least 30 seconds per vehicle
during the highest hour, but,

TRAFFIC ENGINEERING STUDY
(3) If the 85-percentile approach speed of the major -street traffic exceeds 65
Km/h (40 mph), the minimum vehicular volume warrant is 70 percent of
the above values.
D. Where no signal criterion is satisfied, but where Criteria B, C.1, and C.2 are all
satisfied to 80 percent of the minimum values. Criterion C.3 is excluded from this
condition.
Option:
Other criteria that may be considered in an engineering study include:
A. The need to control left -turn conflicts;
B. The need to control vehicle/pedestrian conflicts near locations that
generate high pedestrian volumes:
C. Locations where a road user, after stopping , cannot see conflicting
traffic and is not able to safely negotiate the intersection unless
conflicting cross traffic is also required to stop;
D. An intersection of two residential neighborhood collector (through)
streets of similar design and operating characteristics where
multi -way stop control would improve traffic operational
characteristics of the intersection.
FINDINGS AND RECOMMENDATIONS
Several methods of controlling conflicting streams of vehicles at intersections are in use.
The use of any one of these methods depends on the type of intersection and the volume
of traffic in each of the conflicting streams. Based on field investigations, traffic data
collected as part of this study, it is evident that the tire marks at the curb line within the
TRAFF DATA & ASSOCIATES. INC. 4

traffic circle are the result of tight turning radii. Although there are no police accident
report at this location. However, residents of the subdivision have seen several vehicles at
the lawn in front of the traffic circle. These vehicles were unable to safely maneuver the
tight turning radii, thereby creating a potential safety hazards. Hence, traffic control
measures should be implemented at the intersection of Keithwood Drive and Adella
Court to minimize the safety related problems. In order to mitigate the impact of the tight
turning radii, while providing safe and efficient traffic operation, one of the possible
solutions is slowing approaching traffic or stop all vehicles approaching the intersection
before entering the intersection. Hence, option A or option B could be implemented.
Option A. Installation of speed table along Keithwood Drive at least 100 feet from the
traffic circle or removal of the traffic circle.
Option B. Installation of a multi -way stop sign that require all vehicles approaching the
intersection to stop before entering the intersection.
In addition to option A or B, the following measures should be implemented.
• The yield signs along Keithwood Drive should be removed.
• Speed advisory and speed limit signs (30 mph) should be installed along
Keithwood Drive. The speed advisory signs should read as follows: Observe
Speed Limit, Traffic Laws Enforced.
