Project objectives

Create a real-time bus tracking system capable of:

1.Friendly website with database which can update real-time location.

2.A self-powered user station with stable performance.

3.Long distance wireless communication with the radius about 1mile.

4.Compact stable on-bus tracking system with high accuracy(error less than 10m)



Working rangeSmall range:

R = 0.6 km

Large range:

R = 1.4 km



Goals

Low

•Self-Made Portable GPS device with LCD demonstrating the location.

•Project Website and dynamic database.

•Long distance RF communication with specific designed antenna.

•Prototype of Wooden user station (maybe holding laptop)

Med

•On-camps single bus tracking

•Display the location directly to the user station.

High

•Whole route multi bus real-time tracking.

•Update real-time information to the website supported by dynamic database.
