SCHOOL ZONE SPEED LIMITS
Ensuring the safety of children on public streets near schools is
the responsibility of parents, school officials and road
authorities. Parents must provide basic training and
supervision in order to develop safe behavior and serve as role
models. School officials must support and encourage
educational safety programs and methods for walking or
biking students. Road authorities must provide a safe
environment on the street by using proven traffic control
methodologies that will minimize the crash probability.
THE LAW
Each road authority may establish school zone speed limits on
roads under their jurisdiction. I .order to provide an objective,
uniform and safe environme o alking and biking students,
Minnesota law requires a~ , c inv ~ ation as prescribed by

SCHOOL AGE PEDESTRIAN CRASHES
While safety is emphasized near schools, pedestrian crash
experience requires a broader look. A Minnesota study
revealed that 88 percent of school age pedestrian crashes
occurred more than one block from school. Similar studies in
Idaho showed only 13 percent of school age pedestrian crashes
occurred in a school zone but 31 percent occurred on the trip to
school. Other states have confirmed similar results. The
statistics point out that location is NOT the predominant factor,
suggesting that safety education for pedestrians has the
greatest potential for improvement since they can use it at all
locations.
Further insights can be gathered from analysis of
circumstances contributing to school age crashes.
- Most crashes occurred when the child dashed from behind
parked cars
- Many crashes occur at mid-block locations
- Kindergarten through third grade pedestrians had
considerable difficulty understanding traffic control devices.
In realization of these facts it is apparent that school age child
safety is not a singular issue of speed limits. Real
improvements in safety require a comprehensive study of the
school trip and each environment must be specifically
addressed.
THE TRAFFIC INVESTIGATION
Mn/DOT developed the. booklet "A Guide to Establishing Speed
Limits in School Zones" that is a comprehensive safety outlook
and is the prescribed method as required by MS 169.14. Three
distinct components are addressed-
The School Route Plan
Hazard Identification
Education.
The main objective of the School Route Plan is to establish
walking routes that minimize the number of streets crossed and to
maximize the safety of approved crossings used by children on
the entire trip to school.
Hazard Identification addresses nine issues using the school
route plan and evaluates each street for what is present as well as
what can be changed to enhance the safety of the planned routes.
A quick summary:
1) Roadway geometry- crossing narrower roads in straight
sections with good sight distance increases the safety to
pedestrians.
2) Traffic volumo- low volume roads are safer to cross. High
volume roads will require adult crossing guards for maximum
safety.
3) Pedestrian volumes- number of pedestrians can determine
signal timing or necessitate additional traffic control.
4) Parking- parking should be banned in the immediate area of
any school crossing.
5) Traffic Control Devices- these should be reviewed to verify
they are operating correctly and signs are not hidden by
vegetation.
6) Sidewalks -children walking in the street is dangerous.
Continuous sidewalks that do not intermittently disappear and
force children into the road are the best.
'n Fencing-strategically placed fencing can change walking
patterns and prevent dangerous mid-block crossing. At
playgrounds, it prevents errant kick-balls from rolling into the
street and causing children to chase them from between parked
cars.
8) Crash History -crash investigation can reveal locations
where remedial measures may not be working and pedestrians
should be routed away from these areas.
9) Speed zones- if all other measures have been addressed and a
reduced speed is still required to safely navigate the school zone,
then a school zone speed limit should be considered. Trained
engineering personnel should design speed limits based on the
limiting criteria and arbitrary blanket values should be avoided.
As noted before, education is the most important. All the best
efforts of engineering and planning will be lost if the pedestrian is
unaware of the safe routes and safe practices. Children are rarely
involved in crashes while crossing properly. Education is not the
singular responsibility of one group or person, it requires a
partnership and commitment from all.
