September 11, 2021 Page 59 2040 Build Scenarios Figures 5.1 — 5.3 in Appendix D forecasts 2040 traffic volumes under Concept 1, 2, and 3 build scenarios with increased telecommuting. On average, these forecasts show five percent fewer trips than the 2040 build scenario forecasts developed using traditional telecommuting assumptions. The following paragraphs identify roadway segments with the largest decrease in traffic volume under each build scenario. Concept 1 Under the Concept 1 scenario, highways with the biggest change in year 2040 traffic volume due to increased telecommuting are the Highway 610 river crossing (126,900 to 120,600 vpd), I-94 west of Highway 101 (85,800 to 79,800 vpd), and I-694 west of US 169 (133,600 to 127,900 vpd). Total ADT using a northwest metro area bridge is expected to decrease from 248,500 to 232,300 vpd, representing a seven percent decrease in volume. Concept 2 Under the Concept 2 scenario, highways with the biggest change in year 2040 traffic volume due to increased telecommuting are the Highway 101 river crossing (62,700 to 56,800 vpd), I-94 west of Highway 101 (85,900 to 80,000 vpd), and Highway 252 between Highway 610 and I-694 (126,800 to 120,900 vpd). Total ADT using a northwest metro area bridge is expected to decrease from 250,100 to 235,400 vpd, representing a six percent decrease in volume. Concept 3 Under the Concept 3 scenario, highways with the biggest change in year 2040 traffic volume due to increased telecommuting are the Highway 610 river crossing (121,600 to 115,800 vpd), I-94 west of Highway 101 (88,100 to 82,700 vpd), and the Highway 101 river crossing (54,200 to 48,900 vpd). Total ADT using an existing northwest metro area bridge is expected to decrease from 226,700 to 211,000 vpd, representing a seven percent decrease in volume. A daily traffic sensitivity analysis was not performed for Concept 4. It is assumed the sensitivity of year 2040 traffic volumes for Concept 4 reflect the sensitivity of year 2040 traffic volumes modeled for Concept 3.
