14.3.1 Project Overview
LMU Programming – Taxi System
The final project we are going to look at is for the Hagensville Cab Company. The
Hagensville Cab Company is a small organization with approximately 20 vehicles and, as of
late, has been losing business to larger fleets. The owners are hoping that by adding a GPS
device they can improve their efficiency and add a couple of services their competitors do
not offer. They are looking for the following:
• Real-Time updates from each vehicle
• Distance travelled, drive times and idle times for maintenance purposes
• Messaging between the cab and the back end system (i.e. dispatch)
• Real-Time Credit Card processing (they’ve had a few problems with fraudulent credit
cards)
• Notification of when a cab becomes available
For their backend piece they are looking for two applications. This first application is to be
used by their dispatcher to route cabs to the nearest customer as well as run management
reports. The second application is to be part of their external website and is designed to
allowing visitors to reserve the nearest cab and view arrival estimates.
14.3.2 Project Proposal
14.3.2.1 LMU Requirements
As with the previous two projects, we will start with the choice of wireless technology. In
this case, the decision will be made based on coverage. All three operators do have coverage
within Hagensville and its airport, however only the CDMA operator has sufficient coverage
in the surrounding suburbs.
On the peripheral and I/O front the LMU will need to be able to handle the following:
• Ignition Sense
• A connection to an MDT for dispatch messaging
• A connection to a card-reader for credit card processing
While we do not need the expanded I/O, the second serial device does mean we need the
AUX port that is only available on the ioPOD.
14.3.2.2 Local Application Requirements
The local application will be in two parts, an MDT to handle messaging between the driver
and the dispatcher and a credit card reader to handle payment processing. We are planning
to take advantage of the LMU’s User Messaging feature to handle both devices. As
mentioned, this means that we will need the ioPOD with Aux Port.
