2.2.2 National access management success—case studies<br />
Other states with experience implementing access management strategies along selected corridors<br />
have documented the resulting benefits. Table 2-3 lists the benefits <strong>of</strong> selected corridor access<br />
management treatments from across the country. In all cases, the access management techniques<br />
decreased the crash rate, especially at intersections. The techniques used varied by location and<br />
were appropriate for that roadway.<br />
