Access management is a set of street design techniques that control where vehicles may enter and leave the road. Examples include the spacing, design, and operation of driveways, turns, medians, and intersections. Properly designed access management reduces stop-and-go situations that lead to collisions. Effective access management involves balancing the traffic movement and access to the properties along the road. When driveways are too close to intersections, traffic backups affect crossstreet traffic flow and safety. In retrofit situations, public agencies must work with property owners to implement access management.
