Control of Speed and Safety
Each year, the City receives many inquiries about installing stop signs as
way to reduce speeding or improve safety. However, research shows that other
measures are often more effective in addressing the issues of speed and safety
than adding stop signs. The purpose of stop signs is to assign right-of-way at
an intersection, not to control speeding. Also, stop signs do not necessarily
improve safety at an intersection.
Frequently, residents think stop signs at an intersection are needed because
an accident has occurred there recently. It is important to keep in mind that
accidents are random events. Many collisions are the result of driver error and
are not the fault of poor design or insufficient traffic control.
The City does review accident records periodically to determine if patterns
of multiple collisions occur at particular locations. When several collisions
occur at the same location, engineering studies are performed to determine the
need for possible corrective action. Removal of sight obstructions and other
measures are considered as well as the possibility of additional stop
signs.
Public understanding of the function of stop signs is one of the most
critical elements in reducing speeding and traffic accidents. The following
information explains Wiggins policies on intersection traffic control and the
correct use of stop signs.
Philosophy of Traffic Control
Effective traffic control is achieved by exercising the least intrusive
control to achieve safe traffic flow. When excessive control or unnecessary
control is used, motorists feel imposed upon and frequently will ignore the
traffic control device. This can lead to severe consequences involving
collisions and possibly personal injury.
Installation Policies
The Federal "Uniform Traffic Control Devices Manual" dictates the
size, shape and color of all traffic signs. This manual has guidelines for
installing signs and thus creates uniformity from state to state.
The City has proposed adopting policies for the installation of two-way stop
signs in residential areas. These policies identify specific traffic volumes,
accident history, and any unusual conditions that must be present at the
intersection before these traffic control devices may be installed.
Our experience has shown that simply improving the intersection visibility
by prohibiting parking or removing vegetation near the intersection is often
more effective in reducing traffic accidents than installing stop signs. This
often reduces the need to install more restrictive intersection controls.
Overuse of stop signs reduces their effectiveness. If signs are installed where
not justified, they are largely ignored with many drivers not making complete
stops.
Two-Way Stop Signs
Two-way stop signs shall be installed at an intersection only after a
careful engineering evaluation of the existing conditions indicates that their
installation is appropriate.
Good neighborhood traffic control produces smooth trips for the motorist and
avoids the "stop and go" effect of excessive stop signs. Experience shows that
motorists have a tendency to speed up between stop signs. This is contrary to
the wishes of residents who want motorists to slow down while traveling on
residential streets.
Two-way stop signs at an intersection may only cost $100 to install but they
can add about $4,600 in additional operating costs per year
for motorists (assuming 500 cars are forced to stop at the
intersection each day). Other costs of unjustified stop signs are:
Increased air pollution when cars are idling at a stop sign;
Increased noise from braking and accelerating; and,
Increased wear and tear on cars forced to slow down, stop and then
accelerate through stop signs.
Our review of stop sign requests includes an examination
of:
Relevant speed, accident records and sight obstructions when
considering a stop sign at a particular location.
If the presence of a sight obstruction is contributing to accidents at the
intersection, staff should seek to remove the obstruction before considering a
stop sign.
If an intersection experiences five (5) or more right angle accidents in a
five(5) -year period, stop signs should be considered.
If fifteen (15) percent of the cars are more than five (5) M.P.H. over the
speed limit, then stop signs should be considered.
If traffic volumes on one of the streets exceed 1,000 vehicles per day, stop
signs may be considered.
Absent engineering data that clearly indicates the need for a stop sign, a
residential intersection should be left uncontrolled.
Removal of stop signs must be approved by the Board of Aldermen.
Four-Way or Multi-Way Stop Signs
The standards for four-way or multi-way stop signs are even more restrictive
than for two-way stop signs.
If an intersection experiences five (5) or more right angle accidents in a
one (1) -year period that are correctable by multi-way stop signs.
If total vehicle volumes entering the intersection from all approaches
average 500 vehicles per hour for any eight hours of an average day.
If the combined vehicular and pedestrian volume from the minor street
averages at least 200 units per hour for the same 8 hours, with an average
delay to minor street vehicular traffic of at least 30 seconds per vehicle
during the maximum hour.
When the 85th-percentile approach speed of the major street traffic exceeds
40 miles per hour, the minimum vehicular volumes can be reduced to 70 percent
of the above requirements.
Rarely do residential areas have the traffic volumes or accident history to
warrant four-way stop signs.
Uncontrolled Intersections
An uncontrolled intersection is the most common form of traffic control for
residential intersections in the City. Motorists need to approach the
intersection cautiously, look both ways and yield to the vehicle on the right.
This is the legal way to enter an uncontrolled intersection.
Citizen Concern
The City takes its role in solving traffic problems very seriously, yet the
ultimate burden of safety rests with you, the motorist in Wiggins. Since we
receive many citizen requests per year, we cannot always investigate them as
quickly as we would like. However, we will respond after carefully evaluating
your request. If action is taken, it can usually take one or two months. We
appreciate your patience and understanding.
