9.2.4 Measures of Effectiveness (MOEs)

9.2.4.1 Travel Demand Model Outputs

For macroscopic analysis using TDM outputs, typical MOEs include VMT, VHT, vehicle hours of congestion delay, vehicle hours of traffic control delay, travel speed, volumes, and the v/c. LOS can be computed using the volume-tocapacity ratio. The thresholds for LOS vary by location and the agency’s expectation of congestion level. Refer to
Appendix R, Section 3 – Traffic Tool Outputs
for a TDM output

.

9.2.4.2 Service Volume Tables

LOS can be determined using the generalized service volume tables. The LOS is based on volume and capacity thresholds.
