When is it not advisable to install a marked crosswalk alone?

An example of a location where a marked crosswalk alone typically does not work and should not be used without further substantial safety improvements is when an uncontrolled marked crosswalk crosses four or more travel lanes and the average daily traffic (ADT) well above 10,000 motor vehicles per day. At a location like this, a marked crosswalk without an accompanying traffic signal or other treatment is not recommended.

However, marked pedestrian crosswalks, in and of themselves, do NOT slow traffic or reduce pedestrian crashes.
There are several reasons to install marked crosswalks, a few being;

What role does Engineering play in Safe Routes to School?

Engineering is one of the complementary strategies that Safe Routes to School (SRTS) programs use to enable more children to walk and bicycle to school safely. Communities tailor a combination of engineering, education, encouragement, and enforcement strategies to address the specific needs of their schools.

Putting Safety in the Safe to School Program: A School Administrator's Guide

Many school administrators are unfamiliar with traffic control and
safety devices. Also, many smaller communities do not have a
traffic engineer or planner on staff. The purpose of this booklet
is to give school administrators a brief overview of safety devices
that might be incorporated into a local plan. We hope that you will
find this booklet of use in planning your community's Safe Routes use in
to School program.
