What do "access management" principles aim to achieve?

Access management principles are focused on optimizing the function and safety of transportation networks by controlling how and where vehicles and pedestrians enter and exit roadways. Specifically, the correct answer emphasizes the importance of managing the design, placement, and spacing of access points for driveways, intersections, and access roads.

By carefully planning these access points, access management aims to minimize conflicts between traffic streams, enhance safety for all road users, and improve the efficiency of traffic flow. Well-designed access points help to reduce the number of potential points where collisions can occur, create smoother transitions for vehicles entering and leaving roadways, and maintain safer conditions for pedestrians and cyclists.

In contrast, increasing the number of access points, reducing road maintenance needs, or allowing unrestricted access to properties can often lead to congestion, increased accident rates, and higher maintenance costs. These alternatives do not align with the goal of promoting safe and efficient movement through a roadway network. Access management seeks to balance accessibility with safety and operational efficiency, which is best achieved by controlling how access points are designed and situated.
