All-Way Stop Request at Reserve Lane and Sierra Rose Circle
end
INTRODUCTION:
The Department of Public Works received a request to perform an All Way Stop Warrant Analysis at the intersection of Reserve Lane and Sierra Rose Circle.
Existing Conditions
The intersection of Reserve Lane and Sierra Rose Circle is a three-way or ‘T’ intersection with stop control on Sierra Rose Circle only. Both Reserve Lane and Sierra Rose Circle are classified as residential streets. The Speed Limit on both streets is 25 mph.
Traffic volume counts were taken on March 11 and 12, 2025.
Reserve Lane has an Average Daily Traffic (ADT) volume of 194 vehicles per day and Sierra Rose Circle has an ADT volume of 24 vehicles per day.
MUTCD All-Way Stop Warrant Analysis
The Manual on Uniform Traffic Control Devices (MUTCD) is the national standard for all traffic control devices installed on any street open to public travel. The City of Joliet Department of Public Works follows the guidelines set forth in the MUTCD. Further, the City of Joliet City Council approved Ordinance No. 17480 that requires the City of Joliet to conform with the minimum MUTCD requirements for multi-way stop sign requests.
Section 2B.06 of the MUTCD specifically states that Stop signs shall not be used for speed control. The Federal Highway Administration and various State Department of Transportations have conducted traffic studies with conclusions showing negative impacts resulting from unwarranted stop sign installations. Examples of the impacts include:
• Increase in mid-block speeds.
• Increase in stop sign violations.
• False sense of security to motorists and pedestrians.
Section 2B.12 of the MUTCD pertains to All-Way Stop Control. The decision to establish all-way stop control at an unsignalized intersection should be based on an engineering study. The engineering study for all-way stop control should include an analysis of factors related to the existing operation and safety at the intersection, the potential to improve these conditions, and the applicable factors contained in the following all-way stop control warrants:
All-Way Stop Control Warrant A: Crash Experience
All-Way Stop Control Warrant B: Sight Distance
All-Way Stop Control Warrant C: Transition to Signal Control or Transition to Yield Control at a Circular Intersection
All-Way Stop Control Warrant D: 8-Hour Volume
All-Way Stop Control Warrant E: Other Factors
Warrants A and D apply to the intersection of Reserve Lane and Sierra Rose Circle and are summarized below:
Warrant A - Crash Experience
All-way stop control may be installed at an intersection where an engineering study indicates that:
For a four-leg intersection, there are five or more reported crashes in a 12-month period or six or more reported crashes in a 36-month period that were of a type susceptible to correction by the installation of way stop control.
For a three-leg intersection, there are four or more reported crashes in a 12-month period or five or more reported crashes in a 36-month period that were of a type susceptible to correction by the installation of way stop control.
There were no crash reports from 2020-2025.
Result - Not Warranted
Warrant D - 8-Hour Volume
All-way stop control may be installed at an intersection where an engineering study indicates:
A. The combined motor vehicle, bicycle, and pedestrian volume entering the intersection from the major-street approaches is at least 300 units per hour for each of any 8 hours of a typical day; and
B. The combined motor vehicle, bicycle, and pedestrian volume entering the intersection from the minor-street approaches is at least 200 units per hour for each of any of the same 8 hours.
There were no hourly volumes that meet these criteria. The attached traffic volume summary details that the 8-hour minimum volumes are not met.
Result - Not Warranted
SUMMARY:
Based on a review of the above-mentioned items, the Department of Public Works has determined that an All-Way Stop at the intersection of Reserve Lane and Sierra Rose Circle is not warranted.
RECOMMENDATION:
recommendation
The Department of Public Works recommends denying the request for an All-Way Stop installation at the intersection of Reserve Lane and Sierra Rose Circle.
