A synthesis of best practice was done to come up with a "best design" of crosswalks used by children. The analysis is based on studies from three sites in Sweden and three in Israel, research results concerning "ideal" interactions, and a review of additional countermeasures as described in the literature.

Our presumption is that actual vehicle speeds should be below 20 km/h where children (aged 7 to 12 years) are crossing a street, especially if they are walking unaccompanied by an adult. The results of field studies show that a "best design" to reach this should include a speed-reducing device located before the crosswalk. The optimal distance from such a device to the crosswalk is about 10 m if the speed limit is 30 km/h or lower. For streets with 50 km/h speed limits, a longer distance of 15 to 20 m is needed and, as a complimentary measure, the crosswalk itself should also be elevated. At approaches with two lanes or more, multiple-threat conflicts occur due to vehicles overtaking stopped ones in the adjacent lane. These conflicts are a threat especially to children, as they often are hidden behind the stopped vehicle if it has stopped too close to the crosswalk. To provide a stronger message for alerting drivers to stop and to stop early, and not to overtake a stopped car in an adjacent lane, advanced yield bars or stop lines are needed. For those, a distance to the crosswalk of about 10 m is recommended. To secure travel speeds below 20 km/h, additional measures like camera enforcement of speeds near the crosswalk might be needed.

Within a few years, ITS technology may govern speeds at marked crosswalks, and speed-reducing measures will be less needed at that time. However, for the foreseeable future, older vehicles lacking such technology will still be allowed on streets and even in newer vehicles, speed-control systems may be voluntary and possible to switch off. Therefore, we believe that investments into the measures discussed in this paper will have a role to play for decades to come.
