Real-time Traffic Navigation System in Symbian Operating System

Abstract:

To design and develop the real-time traffic navigation system (RTTNS) in Symbian operating system (OS),several key technologies were studied.The R-tree spatial index structure was improved based on Hilbert fractal and minimum boundary rectangle (MBR) decomposion.Active object was utilized to deal with non-preemptive multitasking in Symbian OS.A portable vector map library was designed with “Open C” technology.A RTTNS was developed in Symbian S60 OS.The experiment results of several cities show that the RTTNS is highly stable and effective.

Key words:real-time traffic navigation; Symbian operating system; spatial index
