Most outputs are stored within the project directory under "ctramp_output", "skims", "trn", and "other" folders, each with its respective files.
Skims
TM2 produces multiple types of network LOS indicators, often called skim matrices. The following skims are output and generated for each of the five time periods.
Extra added wait time due to full capacity vehicles
[TimePeriod]_[Set]_TOTALWAIT
Total wait time
[TimePeriod]_[Set]_XFERS
Total number of transfers
[TimePeriod]_[Set]_XFERWALK
Walk time between transfers
[TimePeriod]_[Set]_TOTALWALK
Total time involved walking
[TimePeriod]_[Set]_IN_VEHICLE_COST
In vehicle cost
[TimePeriod]_[Set]_CAPPEN

CTRAMP Output
TM2 produces the following tour and trip microsimulation trip lists for both individual and joint travel. The files output are listed below. The modes are defined in Tour and Trip Modes below.
It is important to consider occupancy when reviewing these tables. The model generates person trips. A mode is chosen for each person trip, for personal vehicle travel this could be SOV, HOV2, or HOV3+. At an aggregate level, 100 HOV2 person trips must result in 50 vehicle trips. While this is true at an aggregate level, it may not be possible to pair up all HOV2 person trips produced in the model. But the model produces enough HOV2 person trips to match the target mode share. When reviewing the joint table remember that these records include all travelers. So only one row per trip, as opposed to one row per person or traveler.
