• Upgrade cab dispatch system for Confidential the old Confidential dispatch system communicates with cab drivers via radio and pager, the new system installs GPS on the Laptop for each cab, and the server communicates with each individual cab via wireless communication, an Apache ActiveMQ is built as a Java Message Service JMS between the dispatch server and the cabs, because the drivers now send message embedded with his GPS coordinate to the dispatcher server, the dispatcher server could know location of each cab and do the dispatch job more fair and more efficient.
• System maintenance, fix defects, production release, train the drivers to use the new system
