A mobile data terminal (MDT) or a mobile computer facilitates a real-time data connection for communication between drivers and the dispatch center as the drivers’ runs progress.

The following table explains some of the terms that are used in this guide.

The following sections provide an overview of what can be accomplished in the Dispatching screens in Trapeze PASS:

Additional technical assistance is available from different sources.

Before working with certain Trapeze applications (for example, PASS and FX), you must log on to the Trapeze4 Workstation.

The first time you log into the Trapeze4 Workstation or if your password has expired, you have to change your password.

Exit the system correctly to prevent corruption of the database.

Expand the map to full screen to view a larger map area.

The filters on the Run/Vehicle Options pane allows you to view either a list of runs or vehicles.

If you are viewing runs, only the runs assigned to a mobile computer will have AVL data.

Vehicles can be located by using the poll function.

Define viewing criteria in the Itinerary/AVL Options frame to show information in the Itinerary/AVL grid and on the system map.

To view a vehicle’s turn list, you must have a trace displayed on the map.

Animation settings control the playback of Itinerary/AVL data on the map.

Itinerary and AVL events can be viewed manually on the system by using specific control options.

The AVL Agent improves system scalability by allowing processing of AVL data to be handled separately from other data received from the mobile computer.

When troubleshooting, you may find it necessary to log on a driver in MDT Center.

The MDT Center is a utility within the Trapeze4 workstation that displays messages received from a mobile computer such as requests for no-shows, text messages, or emergency messages.

Many MDT Center commands provide you with quick access to relevant trip information in Schedule Editor or other screens.

Use filters when you need to view all messages from one or multiple vehicles.

Details about MDT vehicles can be gather directly from MDT Center.

As a dispatcher, you are responsible for monitoring messages as they come in, dealing with each message, and closing each message.

You may not see all the message types described here or you may use some message types that are not shown here.

Messages selected as high priority are sent before other messages when there is a queue of messages in the MDT Server.

Canned messages are written in advance and selected from a set list.

Canned messages are written in advance, while Free Form messages are written in the current session. Both are selected from a set list.

The MDT Center is important for communication between dispatchers and drivers.

Drivers may send No Show (NS) messages when the clients do not show up for their scheduled pick-ups.

When a client cancels at the door, the driver sends the MDT center a CD message type.

Emergency messages must be cleared before new trips can be sent to the driver.

Comments can be added to messages received from mobile computers.

Completed messages can be reviewed to determine who marked the message as done and when it was marked as done.

Message data from previous days can be viewed when needed.
