A high-scalable core telematics platform design for intelligent transport systems

With the popularization of telecom/consumer electronics, such as on-board units (OBUs) and personal navigational devices (PNDs), telematics services are becoming more important and practicable in our daily lives. Additionally, when the applications of global positioning system (GPS) are ubiquitous today, OBUs/PNDs can provide people with very convenient location-based services (LBS), plus intelligent transport systems (ITS). To support efficient and effective telecommunications between a huge number of devices and the ITS services, a scalable networking platform is hence demanded. In this paper, we present a high-scalable design to support an open architecture platform for telematics services based on international standards. The proposed core telematics platform (CTP) can optimize the data transmission under linearly increased time complexity by employing a high-scalable architecture design when a large number of devices connect to the application servers. The simulations and experimental results have verified the effectiveness and efficiency of this high-scalable CTP design.
