All-Way Stop Warrant Analysis Valley Road & Mitchell Street Project No.: 230143 December 28, 2023 Page 7 of 10 We utilized the following criteria in evaluating the study location for the application of an All- Way STOP treatment. Based upon MUTCD, Section 2B.12-17, All-Way Stop Control, the following justification is provided: Section 2B.12 All-Way Stop Control Support: 01 The provisions in the following sections describe warrants for the recommended engineering study to determine all-way stop control. Warrants are not a substitute for engineering judgment. The fact that a warrant for a particular traffic control device is met is not conclusive justification to install or not install all-way stop control. Because each intersection will have unique characteristics that affect its operational performance or safety, it is the engineering study for a given intersection that is ultimately the basis for a decision to install or not install all-way stop control. 02 All-way stop controls at intersections with substantially differing approach volumes can reduce the effectiveness of these devices for all roadway users. Guidance: 03 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: A. All-Way Stop Control Warrant A: Crash Experience (see Section 2B.13) B. All-Way Stop Control Warrant B: Sight Distance (see Section 2B.14) C. All-Way Stop Control Warrant C: Transition to Signal Control or Transition to Yield Control at a Circular Intersection (see Section 2B.15) D. All-Way Stop Control Warrant D: 8-Hour Volume (Vehicles, Pedestrians, Bicycles) (see Section 2B.16)

nsition to Yield Control at a Circular Intersection (see Section 2B.15) D. All-Way Stop Control Warrant D: 8-Hour Volume (Vehicles, Pedestrians, Bicycles) (see Section 2B.16) E. All-Way Stop Control Warrant E: Other Factors (see Section 2B.17) Option: 04 The decision to install all-way stop control on site roadways open to public travel may be based on engineering judgment. Standard: 05 The satisfaction of an all-way stop control warrant or warrants shall not in itself require the installation of all-way stop control at an unsignalized intersection. Section 2B.13 All-Way Stop Control Warrant A: Crash Experience Option: 01 All-way stop control may be installed at an intersection where an engineering study indicates that: A. 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 all-way stop control. B. 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 all-way stop control. Section 2B.14 All-Way Stop Control Warrant B: Sight Distance Option: 01 All-way stop control may be installed at an intersection where an engineering study indicates that sight distance on the minor-road approaches controlled by a STOP sign is not adequate for a vehicle to turn onto or cross the major (uncontrolled) road. Support: 02 At such a location, a road user, after stopping, cannot see conflicting traffic and is not able to negotiate the intersection unless conflicting cross traffic is also required to stop. 70 South Orange Avenue, Suite 109 PO Box 99 Livingston, New Jersey 07039 Roseland, NJ 07068 C: (732) 236-7557 T: (973) 228-0999 F: (201) 753-3904 BrightViewEngineering.com
