Best Practice

BEST PRACTICE:

A5−4: Minimum Geometric Standards for Work Zones

DESCRIPTION:

It is Oregon's policy that work zone lane and shoulder widths will meet the minimum geometric standards specified in the Oregon Department of Transportation (ODOT) Highway Design Manual. Internal policy also calls for 300 ft. minimum acceleration lanes.

REASON(S) FOR ADOPTING:

Wider lanes and shoulders increase work zone safety by reducing the potential for sideswipe accidents and truck off−tracking. The safety of construction personnel is also improved because they are farther away from moving traffic.

PRIMARY BENEFIT(S):

Safety is enhanced through the project by reducing the number of potential conflicts often associated with narrow lanes and shoulders.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

Any type of work. This practice is considered for every project. It is most effective for high−volume/high−speed locations.

STATE(S) WHERE USED:

Oregon, Federal Highways
