What Is The Purpose Of Traffic Signals?
Traffic signals-the familiar red, yellow and
green lights, as well as the specialized pedestrian
lights-are designed to let people know who has
the right of way at an intersection or crossing.
Traffic signals help manage traffic flow, allow
pedestrians to cross and give cross-street traffic
a chance to enter the intersection. Pedestrian
signals allow people to cross an intersection safely.
Traffic engineers install pedestrian indicators
on traffic signal posts, using lighted words or
symbols to indicate when it's safe to cross. New
pedestrian signals use symbols which make it easy
to understand, even for those who don't read or
speak English.
Pedestrian Safety Tips:
- Always look both ways before crossing, even
if the signal says "WALK."
- Check for turning vehicles; the motorist may
not see you stepping off the curb.
- Cross the street as quickly as possible.
- Be alert and defensive.
- Avoid crossing where signs tell you it is restricted
or prohibited.
Commonly Asked Questions About Pedestrian Signals
Q. Do I have to use the button to make
the signal work?
A. Yes, use the button for the pedestrian
signal, if one is available. If you don't push
the button, the "WALK" signal will not light
up. Plus, the button allows for additional time
to cross. It is not necessary to press the button
more than once; pushing it again will not speed
it up.
Q. What if the signal says "DON'T WALK" or
the upraised hand signal starts flashing before
I'm through crossing?
A. It's okay to finish crossing the street when the "DON'T WALK" or
hand signal is flashing. The signals are designed to allow plenty of time
to cross safely, as long as the "WALK" symbol is still on. The flashing "DON'T
WALK" or hand signal serves as a warning that it is too late to begin crossing.
Who Decides Which Intersections Need Signals?
Following state and federal guidelines, city
traffic engineers review and evaluate intersections
where signals may be needed. Because traffic and
pedestrian signals are expensive, the city places
them where they will clearly improve safety and
enhance efficiency.
How Do I Get Signals Installed In My Neighborhood?
Many people request new traffic signals in
their neighborhoods. The Department of Transportation
studies over 200 potential locations annually.
The average traffic signal costs $150,000 to design
and construct and $5,000 per year to maintain.
Current funding allows for construction of one
to three new signals each year. Traffic engineers
recommend traffic signal installation based on
the following criteria:
- Intersection collision history
- Number of vehicles using the intersection
- Amount of pedestrian and bicycle activity
- Speed limit
- Other signals in the immediate area
- Intersection characteristics (width, number
of lanes, controls, etc.)
- Visibility
- Type of area (residential, commercial, offices,
recreational, etc.)
- The effect that installing a signal would have
on traffic in the near vicinity.
