Access management refers to the design, application, and control of entry and exit points along a roadway. This includes intersections with other roads and driveways that serve adjacent properties. Thoughtful access management along a corridor can simultaneously enhance safety for all modes, facilitate walking and biking, and reduce trip delay and congestion.
Every intersection, from a signalized intersection to an unpaved driveway, has the potential for conflicts between vehicles, pedestrians, and bicycles. The number and types of conflict pointsâ€”locations where the travel paths of two users intersectâ€”influence the safety performance of the intersection or driveway.
The following access management strategies can be used individually or in combination with one another:
Successful corridor access management involves balancing overall safety and corridor mobility for all users along with the access needs of adjacent land uses.
