Final model (Table 6, p.47) estimated by OLS with White heteroskedasticity-consistent covariance ('hetcov'); t-scores and p-values printed, no SEs. Table 5 (p.46) compares four test models (coefficients and t-scores only; adj. R2 .595-.597; SE type not stated, assumed same OLS). Scanned PDF: numbers checked against the page image. Sign inconsistency in Table 5: PCTBADEG printed -0.0161 (Model 1) and -0.0165 (Model 4) with positive t-scores (7.06, 7.23) while Models 2-3 and Table 6 print positive coefficients; flagged medium confidence. HIGH85/350/550 and WIN85/350/550 are distance bands (feet) to a high-traffic / any arterial, mapped to highway_distance as dummies; LINKDIST = distance to nearest arterial link (feet). Traffic-group dummies (UNKNDUM medium, NOTRADUM low traffic) mapped to 'other'."
