PtMS for Windows is a network based software system using a Windows SQL Server database. It is designed to handle the process of taking trip requests for transportation services, scheduling those requests by assigning them to vehicles or providers, managing the delivery of the transportation services by assisting dispatchers with tracking the completion of the trips and making schedule adjustments/assignments as needed, and recording the completion of the services into a trip transaction/history table used to produce reports and billings.

PtMS Mobile is an extension of the PtMS for Windows transportation management, scheduling and reporting system. Its purpose is to improve the efficiency of the paratransit operation and improve the productivity of the service (more trips per hour).

PtMS Mobile aims to achieve these by:

• streamlining communication between dispatcher and driver
  
• capturing trip information electronically relieving the driver manual recording of trip results
  
• delivering schedule changes directly to the driver minimizing radio chatter
  
• updating the PtMS dispatcher's network system in real time with trip results
  

This document will outline how the PtMS Mobile system is designed to achieve these results. It will cover the following components of the PtMS Mobile system:

• PtMS Mobile Data Exchange Design (between PtMS for Windows and Mobile Units)
  
• PtMS Mobile Voice over Internet and Instant Messaging (IM)
  
• PtMS Mobile Database Design
  
• PtMS Mobile Unit (On-board Computer) Specifications
  
• PtMS Mobile Dispatcher User Interface
  
• PtMS Mobile Unit Driver User Interface
