UCSC maximum housing scenario would have a noticeably positive effect on LOS at Westside intersections both with and without Eastern Access, with greatest benefits without Eastern Access at Bay-High. EAOC (Eastern Access Oversight Committee) Report (1992) congestion

Improving TSM from 40% (assumed in ASMPS) to 60% would not significantly change traffic projections. EAOC congestion

The ASMPS analysis concludes that a number of improvements will be needed in the major commute corridors leading to the University both with and without the Eastern Access Road. More improvements would be necessary along the existing corridors which serve UCSC if the Eastern Access Road were not built than would be needed if it were built. … High St. would see the greatest reduction in traffic volumes from an Eastern Access Roadway with 47% less traffic. Other than High St., the ASMPS shows that an Eastern Access Road would provide only minor relief to traffic congestion on other west side arterials; with the Eastern Access Road, there would be 11% less traffic on Bay Dr. south of Escalona and 4% less traffic at Hwy 1 / Mission St. east of Bay Dr. than without the Eastern Access Road.

Reducing the background growth assumption by 50% has a more significant impact on reducing traffic volumes on the westside than an Eastern Access roadway. EAOC 4.d congestion

The effect of new roadways on traffic on existing streets is more dramatic than is the effect of the changes on land use considered. EAOC App. D road expansion

UCSC at 30% TSM in ‘91; 40% assumed in ASMPS is considered amibitious; the probability of 50-60% goals being achieved is very small -- not advisable to rely on such unlikely possibilities. EAOC App. H: Ron Marquez 12/17/91 transit

Expected city traffic growth rate is 1.77%/y = 1.01%/y (from regional population growth) + 0.76%/y (from increased travel). [City population increased 1.2%/y and city traffic 3.92%/y from ‘74 to ‘86. Half of city traffic increase is assumed due to increased travel and half due to regional population growth.] EAOC App. J: ASMPS Bkgrd Assumptions congestion

Expected state highway travel growth rate is 2.8%/y. [Growth was 5.7%/y from ‘82 to ‘92] EAOC App. J: ASMPS Bkgrd Assumptions congestion
