► Time-of
of-Day (TOD)
TOD assignments conduct separate assignments for each time
period modeled then the loaded networks are combined into a
single loaded network.
Daily trips are generated by summing the period trips from a
TOD assignment.
Typical four period model divided into: Morning Peak, Mid-day,
day,
Evening Peak, Overnight.
Trips are modeled directionally according to time period using
statistically derived Time-of
of-Day factors.
Period and directional counts are needed to validate TOD
assignments.
Allows for a more detailed analysis of congestion during peak
periods.
