Defining ATIS Parameter Sets

Parameter sets for ATIS are defined in System Properties.

Before you begin

Open the Trapeze4 Workstation.

About this task

Create a default parameter set for requested pick-up times and another one for requested drop-off times. If your site does not use requested drop-off times, you only need to create one default parameter set.

Procedure

  1. Click Tools > System Properties.
  2. On the Profile tab, click IPA > ATIS Parameters Sets.
  3. Click Edit.
    The ATIS Parameters dialog box appears.
    The ATIS Parameters dialog box with no Parameter Set selected.
  4. Type or select the desired settings.
    Appropriate configuration of ATIS parameters varies among sites. The following includes general recommendations:
    Parameter Set
    Parameter set to use.
    Minimize
    What should be minimized for trips: Time, Transfer, or Walking.
    Max Walk
    Maximum distance a client can walk.

    This is used to calculate the time required to walk the distance between a point and a stop. Specify a maximum walk distance to have PASS-IPA ignore solutions that require distances exceeding it.

    0.99 is recommended.

    Walk Speed
    Average speed that a customer walks.

    1.75 miles per hour is recommended.

    Walk Origin
    Maximum distance to search for stops at the trip origin.

    1 mile is recommended.

    Walk Destination
    Maximum distance to search for stops at the trip destination.

    1 mile is recommended.

    Walk Increase
    If selected, the distance is increased at the trip origin/destination if no stops are located within the specified distances.

    Clearing the check box is recommended.

    PU Threshold Time
    Offset for the time range within which ATIS searches.

    This value is entered in minutes. For example, entering -30 would cause ATIS to start its search 30 minutes prior to the requested pick-up time. If this parameter is not used, ATIS will search forward from the requested pick-up time.

    DO Threshold Time
    Offset for the time range within which ATIS searches.

    This value is entered in minutes. For example, entering 30 would cause ATIS to start its (backward) search 30 minutes after the requested drop-off time. If this parameter is not used, ATIS will search backward from a requested drop-off time.

    Max Initial Wait
    Ensure that this matches the value specified in the Trapeze6 property Properties > PASS > PassInfoServer > ATIS > SearchWindowTime.
    Max Trip Time
    Maximum trip time.

    This value is entered in minutes.

    Max Answers
    Maximum number of trips to return.

    Set this to 1.

    Max Transfers
    Maximum number of allowed transfers.

    4 is recommended.

    Mode
    Transit mode to use when planning trips:
    • A (all)
    • B (buses only)
    • R (rail only)

    All is recommended.

    Transit Mode
    Transit mode to use when planning trips:
    • B (bus)
    • R (rail/subway)
    • T (train or light rail)
    • X (express bus)
    • C (commuter rail)

    Selecting no options is recommended.

    Lesstime
    This parameter does not apply to PASS-IPA.
    Accessible
    If selected, only accessible stops will be used.
  5. Click Save.
    The Save Set As dialog box appears.
  6. In the Set Name field, type a name for the parameter set.
  7. Click OK.
