Allowable Violations

Allowed violations are violations that are ignored when they occur; therefore, they are not listed as such or are disregarded when calculating solutions.

Table 1. Description of Allowable Violations
Violation Description
SE Occurs when the scheduled trip time is earlier than Scheduled Early Tolerance by the specified number of minutes.
SL Occurs when the scheduled trip time is later than the Scheduled Late Tolerance by the specified number of minutes.
RE Occurs when the requested trip time is moved earlier than the Requested Early Tolerance by the specified number of minutes.
RL Occurs when the requested trip time is moved later than the Requested Late Tolerance by the specified number of minutes.
HO Occurs when the Max Hostage Time is violated by a specified number of minutes.
ATB Allows users to extend the RL buffer time. Available when a buffer is set and an RL is used.
FX (FLEX only) Occurs when the Fixed Route stop time is violated by a specified number of minutes.
OB Occurs when the passenger is on board the vehicle beyond the OBT tolerance by specified number of minutes.
RnE Occurs when the run is pulling out earlier than its tolerances.
RnL Occurs when the run is pulling out later than its tolerances.
WK Occurs when the client is required to walk too far to a bus stop in a Flex/Fixed solution.

Type the number of minutes by which the walk time can be exceeded without violation.
TL Transfer Layover violation occurs when the pick-up at the transfer point is late.
TT Occurs when the drop-off at the transfer point is late.
DUR Duration of Stay violation occurs when the minimum/maximum time set between one client’s drop-off and next pick-up is violated.

For example, if the client's duration of stay has been violated by five minutes, the system displays the DUR + (the amount of time that has been violated).
RLe Occurs when the run is operating more hours than specified (the length of the run is in excess).
ETVTE Occurs if an event’s estimated time, specifically for pick-ups on Taxi run types (not para type runs), is greater than X minutes of the event’s Scheduled Early Time.
CAP Allows the system to schedule a run exceeding its vehicle capacity without violation. If unselected, a violation occurs whenever the vehicle exceeds its capacity.
RnP Occurs when the run is violating a polygon boundary showing that the run is out of the specified service area.
PR

Occurs when the restrictions of the provider are not applied. For example, a booking is assigned to a provider that is different from the one assigned to its scheduled run.

If the system property PASS Scheduling > Enforce Client Providers is set to Yes, the allow PR violation option does not apply and no alternative provider options will be shown.
BrO Occurs when a break is scheduled with a client still on board or a break actually begins either before the earliest time or after the latest time specified for the break to start.
BT Occurs when a vehicle has exceeded the Backtrack Threshold.
SER Allows users to find solutions where an event violates the ParaService Type for a Run.
CD Allows users to find solutions that violate the Co-Driver Requirement for a Run.
LIFO The Schedule Server arranges trips (based on capacity type, space type, or mobility aids) in such sequences that the drop-off occurs immediately after the pick-up (last in/first out).

This is useful when you want to avoid situations where, for example, a client must be moved out of a vehicle temporarily to allow others to be picked up or dropped off.
COV Occurs if the client has multiple trips with schedule times that overlap. (Client Overlap)
MA Occurs when a mobility aid that a client requires is not provided by the vehicle.

This only applies to mobility aids that must be provided by the transit property, not ones that the clients provide themselves. Examples include stretchers and stair climbers. This is predominantly associated with mobility aids requiring garage pick-up or driver assistance.
RAR Occurs when a run travels into polygons that conflict with the polygon rules of the Para Service Area Route to which it is assigned. (Run Area Route)
SAR Occurs when the pick-up or drop-off is in violation of a Para Service Area Rule. (Service Area Rule)
MG Occurs when a non-group member is scheduled on a run at the same time as an exclusive group.
VT The Schedule Server’s VehicleTypeExclusions list generates a new vehicle type violation (VT) on a pick-up event that is placed onto a run to which an incompatible vehicle type is assigned.
TM A booking is manually placed on a run of an invalid mode type. (Transit Mode)
BrR Occurs when a manual break is put on a run with an autobreak rule or an autobreak violates a logical condition. (Break Run)
LC Location Capacity Violation. There are too many vehicles with overlapping times at a location for the curbside capacity available.
EsG, EsD, EsA Escort violations used in PASS-ED.
A Accessibility. Used mainly in Europe.
EX Service exclusions.
PC Paracluster violation. Used mainly in Europe.
CQ Occurs if a provider has already met the allotted costing quota during a time interval and additional passenger with this space type is scheduled on to a run. For more information, refer to the PASS-CT System Administrator and User Guide.
CPR Occurs when a client trip has been placed on a run for a provider that is not included in the client’s list of valid providers (defined in Client Registration on the Providers tab).
SRSQ Occurs when the stop sequence defined for the run in Task > Runs on the Stop Restrictions tab is not followed.
SRST Occurs when the trip includes an Origin or Destination that does not match the stops defined in Task > Runs on the Stop Restrictions tab for the run.
R Occurs for runs that are going to a restricted location while they have clients or employees not authorized to access that location. R violations are incurred on the event at which unauthorized passengers are included.
