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.
A marked crosswalk can benefit safety for pedestrians by directing them to the best crossing locations. Marked crosswalks should direct students to cross at locations where appropriate traffic control, including traffic signals or adult school crossing guards, either currently exist or can be provided. 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;
High-speed motor vehicles pose a serious threat to the safety of children who are crossing streets. One of the biggest challenges in providing children with safe walking and bicycling routes to school involves slowing down traffic.
Children that walk or bicycle to school need safe and well-designed facilities between their home and school. The following describes the types of infrastructure found along the school route that improve the condition for walking and bicycling including;
