Which of these items should be identified on a route map?

A route map is primarily designed to represent specific aspects relevant to navigation or transportation. In this context, the correct identification of parks on a route map serves a distinct purpose. Parks are relevant landmarks that can inform travelers about points of interest along their journey, providing areas for rest, recreation, or scenic views. They help in planning routes that enhance the overall travel experience.

Although cable junctions, utility poles, and warning signs may be significant for utility or safety considerations, they are not typically highlighted on a general route map as points of interest. Their inclusion might clutter the map and detract from its primary purpose of guiding users efficiently along a route. Thus, recognizing parks on a route map aligns with enhancing travel utility and enjoyment.
