tot_dropoffs |
INTEGER |
NO |
0 |
Total number of dropoffs successfully completed by vehicle in the simulation |
|
num_same_OD_trips |
INTEGER |
NO |
0 |
Integer value recording if there were trips starting and ending from the same location/link |
|
enroute_switches |
INTEGER |
NO |
0 |
Total number of reroute/detours requested of the vehicle while serving all trips |
|
charging_trips |
INTEGER |
NO |
0 |
Total number of trips to an electric vehicle charging station made by vehicle |
|
maintenance_trips |
INTEGER |
NO |
0 |
Total number of trips for maintenance made by vehicle |

revenue |
REAL |
YES |
0 |
Total revenue earned by vehicle in serving requests while in operation |

target_income |
REAL |
YES |
0 |
If human driver, an estimate of target income desired to be earned by driver while in operation |
|
initial_loc |
INTEGER |
NO |
0 |
Location ID consistent with the Location table of where the vehicle began operations from in the simulation period |
|
final_loc |
INTEGER |
NO |
0 |
Location ID consistent with the Location table of where the vehicle ended operations at in the simulation period |
|
trip_requests |
INTEGER |
NO |
0 |
Total number of requests passed along to the vehicle after several conditions are evaluated (such as proximity and detour if shared) |
|
trip_rejections |
INTEGER |
NO |
0 |
If human driver, total number of requests rejected by driver. Always lesser than or equal to trip_requests. |
|
driver_rating |
REAL |
NO |
0 |
Driver rating set from a distribution and tracked to repeat across iterations. |
|
service_type |
INTEGER |
NO |
0 |
Integer from an enum list representing the type of service offered by the vehicle. @@ TNC_Service_Types @@ |
|
num_seats |
INTEGER |
NO |
0 |
Number of seats offered by the vehicle, especially useful for pooling but also when requests need a minimum number of available seats. |
