• Narrow lanes.
• Introduce horizontal deflection as part of a chicane configuration in conjunction with or bulb-outs.

• Provide a pedestrian refuge.
  

A median does not have raised curbs except for a bull nose curb on the ends of the median as visual cue and delineation until landscaping matures. Can be later removed.

Median islands are similar to medians but are generally installed at intersections and have raised curbs all around.  Median islands may be used to shorten pedestrian crossing at an intersection and provide an opportunity for landscaping and visual enhancements to a neighborhood. They can also be used as part of a gateway to a neighborhood.
