Real-time Traffic Navigation System in Symbian Operating System
Chen Yingying · Journal of Tongji University · 2010
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.
