12.2.4.2 Delay
Delay is the sum of the deceleration delay, stopped delay, and acceleration delay caused by a roundabout. Geometric delay is not accounted for in the models identified in this section. Delay is calculated using formulas found in the HCM to compute:
- The average control delay for each approach; and
- The overall roundabout control delay
Delay is reported in seconds per vehicle. Values may be rounded to the nearest tenth of a second.
