Small changes can make walking to school safer

Montgomery County could do a lot to make walking to school safer and more convenient, and at little cost. All it takes is a few changes to the law, signs and paint, and retiming some traffic signals.

...

Expand school zones: Amend the county's criteria for school zones to include all county roads within a half-mile radius of a school. This would allow MCDOT to reduce speed limits and increase fines on roads near schools.

Lower speeds and limit unsafe right turns: Change the following rules in the amended school zones and post new signs to inform drivers:

• Establish a maximum speed limit of 20 miles per hour during school hours, including arrival and dismissal. This could decrease the risk of child pedestrian crashes by up to 70%.

• Double the fines for speeding violations, to motivate drivers to slow down.

• Prohibit right turns on red during school hours to reduce conflicts between pedestrians and drivers at traffic signals.

...

Retime traffic signals: Change traffic signal timing in the amended school zones in the following ways, to make it safer for pedestrians of all ages to cross the street:

• Put in leading pedestrian intervals for traffic signals at intersections where at least one of the roads is an arterial, to allow walkers to get a head start crossing busy streets.

• Use a walking speed of 2.5 feet per second to calculate the minimum pedestrian clearance interval, to give everyone, including children and adults pushing strollers, sufficient time to cross.

• Have the walk signal appear during every signal cycle during school hours at intersections with traffic signals, without pedestrians having to push a button. This can be done either by putting the signals in pedestrian "recall" during school hours (including arrival and dismissal) or by removing the pedestrian pushbuttons altogether.

• Shorten traffic signals during school hours (including arrival and dismissal) so kids don't have to wait longer than 40 seconds for a walk signal on any leg of an intersection. This would lead more pedestrians to wait for the walk signal to cross.

...

Change road markings: Add paint to the pavement in school zones in the following ways:

• Mark all crosswalks with a "ladder" or "zebra" crosswalk, using material embedded with retroreflective glass beads. This increases the visibility of crosswalks, raising driver awareness and encouraging pedestrians to cross at crosswalks.

• Narrow traffic lanes to 10 feet, to reduce vehicle speeds, increase drivers' compliance with the 20 mph speed limits, and reduce the length of pedestrian crossings across traffic lanes.
