Luke Wochensky, Mayor Village of East Aurora All-Way Stop Third Party Review: Pine Street & Girard Avenue Intersection September 24, 2026 Page 2 in a memo to the Village of East Aurora, dated 7/2/2026, and is included in the appendices of this memorandum (see Appendix F). Section 1 - Review of All-Way Stop Recommendation: The 11th Edition of the Manual on Uniform Traffic Control Devices (MUTCD), Sections 2B.12 through 2B.17, identifies five warrants for evaluating all-way stop control. At a three-legged intersection, all-way stop control would require STOP signs on all three approaches. The decision should be supported by an engineering study addressing existing operations, safety conditions, and the potential benefits and adverse effects of requiring all approaches to stop. The MUTCD emphasizes that satisfying a warrant does not, by itself, require installation of all-way stop control; the final determination must be based on engineering judgment. The applicable MUTCD all-way stop warrants are summarized below: Warrant Criteria for a Three-Legged Intersection Four or more reported crashes within a 12-month period, or five or more reported crashes A: Crash within a 36-month period, of types susceptible to correction by all-way stop control. Experience Potentially correctable crashes typically include right-angle and turning-movement collisions. Sight distance from the stop-controlled minor-road approach is inadequate for a stopped B: Sight vehicle to safely turn onto or cross the uncontrolled major road, and the intersection Distance cannot reasonably be negotiated unless the major-road traffic is also required to stop. C: Transition All-way stop control is proposed as an interim measure while arrangements are being Control made to install a traffic signal or to transition to yield control at a circular intersection. For each of the same eight hours of a typical day: (1) the combined motor-vehicle, bicycle, and pedestrian volume entering from the two major-street approaches is at least 300 units per hour; and (2) the combined volume entering from the single minor-street approach is D: Eight-Hour at least 200 units per hour. The eight qualifying hours need not be consecutive. If the Volume major-street 85th-percentile approach speed exceeds 40 mph, the thresholds may be reduced to 70 percent, or 210 units per hour on the major street and 140 units per hour on the minor street. Other conditions indicate that all-way stop control is appropriate, including a need to control left-turn conflicts, an intersection of similar residential collector streets where all- E: Other Factors way stop control would improve operations, or pedestrian and bicycle activity that supports the installation.
