aOffers a comparison with delay-based Level of Service for drivers computed in HCM Chapter 9, "Signalized Intersections"
bOffers a comparison with delay-based Level of Service for drivers computed in HCM Chapter 10, "Unsignalized Intersections"
cOffers a comparison with Level of Service for drivers computed in HCM Chapter 11, "Urban and Suburban Arterials"
dCurrent HCM is ambiguous regarding the definition of minor and major red times (Rmi, Rmj); therefore, the effect of the proposed noncompliance adjustments will depend on the analyst's interpretation of the HCM
