Flex Properties

The following properties are used for scheduling FLEX runs using the FLEX module:

  • Allow flex on garage deadhead: Allows vehicle to deviate off route between the garage and the first fixed stop or between the last fixed stop and the return to the garage.

  • Auto Create Daily Runs: If set to Yes, the Schedule Server automatically creates daily FLEX and FX runs directly from the FX tables even if the run does not have a master run record in PASS. You must reload the Schedule Server when you enable this property. Flex runs that are created if this property is enabled are named with the Line Group Abbreviation and block number. They also start with an “L” prefix.

  • Fixed stop late tolerance: Determines how late the run can be at a fixed stop.

  • Flex if zero slack: If set to Yes, the FLEX algorithm allows route deviation regardless of the slack value. The deviation may or may not result in the FLEX bus arriving late at that node (how late depends on other properties). If it is set to No, the FLEX algorithm does not allow route deviation from the fixed path between the node with zero slack and the previous node. It only allows deviation if the slack is greater than zero.

  • Ignore late at non-node FX Stops: If set to Yes, lateness is computed at nodes (i.e., published time points) only, and not at intermediate fixed stops.

  • Min Stop2Stop Dev. Dis: The minimum distance separation that two sequential stop events must have in order for a client deviation to be allowed to be inserted in between the events. If the minimum distance is not reached, a client deviation is only allowed if the two stop times are different by at least the number of minutes specified by “Min Stop2Stop Dev Time”. Deviations that are not allowed display ES violations.

  • Min Stop2Stop Dev. Time: The minimum time separation that two sequential stop events that fail the “Min Stop2Stop Dev Dis” rule must have in order to allow a client deviation to be inserted in between the events.

  • Transfer Point Late Tolerance: The amount of time that a FLEX vehicle can arrive late at a transfer node before it's considered a violation.
