RE: Use of 4-way stop signs to control speeding and volume in residentia

Guidance:
STOP signs should be used if engineering judgment indicates that one or more of the following conditions exist:

Intersection of a less important road with a main road where application of the normal right-of-way rule would not be expected to provide reasonable compliance with the law;
Street entering a through highway or street;
Unsignalized intersection in a signalized area; and/or
High speeds, restricted view, or crash records indicate a need for control by the STOP sign.

Standard:
Because the potential for conflicting commands could create driver confusion, STOP signs shall not be installed at intersections where traffic control signals are installed and operating except as noted in Section 4D.01.

Portable or part-time STOP signs shall not be used except for emergency and temporary traffic control zone purposes.

Guidance:
STOP signs should not be used for speed control.

STOP signs should be installed in a manner that minimizes the numbers of vehicles having to stop. At intersections where a full stop is not necessary at all times, consideration should be given to using less restrictive measures such as YIELD signs (see Section 2B.08).

Once the decision has been made to install two-way stop control, the decision regarding the appropriate street to stop should be based on engineering judgment. In most cases, the street carrying the lowest volume of traffic should be stopped.

A STOP sign should not be installed on the major street unless justified by a traffic engineering study.

Support:
The following are considerations that might influence the decision regarding the appropriate street upon which to install a STOP sign where two streets with relatively equal volumes and/or characteristics intersect:

Stopping the direction that conflicts the most with established pedestrian crossing activity or school walking routes;
Stopping the direction that has obscured vision, dips, or bumps that already require drivers to use lower operating speeds;
Stopping the direction that has the longest distance of uninterrupted flow approaching the intersection; and
Stopping the direction that has the best sight distance to conflicting traffic.

The use of the STOP sign at highway-railroad grade crossings is described in Section 8B.08. The use of the STOP sign at highway-light rail transit grade crossings is described in Section 10C.04.
