A.Crosswalks exist at all intersections whether they are marked or not. Crosswalks are marked only where necessary for the guidance of pedestrians to direct them to the safest of several potential routes. Studies have shown there is a higher accident rate within marked crosswalks than there is within an unmarked crosswalk. This is due to the fact that pedestrians tend to have a false sense of security within marked crosswalks in believing motorists will automatically yield the right-of-way to them.
A.Speed limits are set based on traffic engineering surveys, which include an analysis of roadway conditions, accident history, and the prevailing speed of prudent drivers. When speed limits are set too low for conditions, some drivers will adhere while others will simply ignore the limit, causing a greater number of conflicts between the slower and faster drivers while reducing the number of gaps with which crossings can be made by side-street traffic and pedestrians.
