Summary of Interim Findings – AM Peak• With three‐lane work zone pattern, 10‐20% diversion will

keep average travel speed over 40mph

• With optimum diversion (equilibrium), network model estimates I‐40 westbound travel time to increase through work zone from 8.6 to 12.7 minutes for three‐lane pattern

• Model estimates 33% diversion for three‐lane pattern

• Model estimates volume increases over 500vph for Wade Avenue, US64, US1, and NC55

• Diversion from I‐40 estimated to result in travel time increases over 30% for I‐440 EB, US70 northbound, Hammond Rd. northbound, and Rock Quarry Road westbound

Summary of Interim Findings – PM Peak• With three‐lane work zone pattern, 40mph average

travel speed can be maintained with approximately 30‐40% diversion.

• With optimum diversion (equilibrium), network model estimates I‐40 eastbound travel time to increase through work zone from 8.6 to 13.9 minutes for three‐lane pattern

• Model estimates 36% diversion for three‐lane pattern

• Model estimates volume increases over 500vph for US70, and over 1,000 vph for US64, US1, and NC55

• Diversion from I‐40 estimated to result in travel time increases over 30% for Wade Ave. EB and Davis Drive SB2626
