96 APPENDIX: POTENTIAL MUTCD REVISIONS INTRODUCTION This appendix provides suggested language recommended for inclusion in the upcoming edition of the MUTCD as developed at the conclusion of the research project. FORMATTING USED WITH REVISIONS Recommended Language The proposed revisions represent a substantial rewrite to Sections 2B.04, 2B.06, 2B.07, and 2B.09.

97 RECOMMENDED LANGUAGE FOR THE MUTCD [Note: Sections 2B.04, 2B.06, 2B.07, and 2B.09 are deleted and replaced with the following.] Chapter 2B.XX Signing for Right of Way at Intersections Section 2B.X1 General Considerations Support: 1 Unsignalized intersections represent the most common form of intersection right-of-way control.

98 8 Portable or part-time STOP or YIELD signs shall not be used except for emergency and temporary traffic control zone purposes. [Note: From 2009 MUTCD Section 2B.04, Paragraph 12.]

99 2 When two roadways that have relatively equal volumes, speeds, and/or other characteristics intersect, the following factors should be considered in selecting the minor road for installation of YIELD or STOP signs: [Note: Similar thought to 2009 MUTCD Section 2B.04, Paragraph 09.]

100 Section 2B.X5 No Intersection Control Guidance: 1 The decision not to use intersection control should be based on engineering judgment that indicates all of the following conditions exist: A Intersection sight distance is adequate on all approaches.

101 D Entering intersection volume of less than 1,800 units per day or 140 units in the peak hour.
|
From page 114... ...
102 Section 2B.X7 Minor-Road Stop Control Guidance: 1 Stop control on the minor-road approach or approaches to an intersection should be considered when engineering judgment indicates that one or more of the following conditions exist: A A restricted view exists that requires road users to stop in order to adequately observe conflicting traffic on the through street or highway.

103 Section 2B.X9 All-Way Stop Control Warrant A: Crash Experience Option: 1 All-way stop control may be established 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.
