This paper introduces the use of the map database as a sensor in driver assistance and awareness applications.Driver Assistance and awareness applications such as Adaptive Cruise
Control (ACC) and Forward Collision warning need to identify the
primary target in the host vehicle lane,which requires accurate estimation
of the geometry of the road between the host and the target vehicle.

Oct 2005 | Comments Off on The conceptual intelligent navigator

The goal of developing any intelligent machine is to mimic human behaviors and achieve certain goals that can not be fulfi lled by adopting conventional methods [Cawsey, 1998].

Sep 2005 | Comments Off on An Alternative Low Cost MEMS IMU/GPS Integration Scheme

This article investigates the use of artificial neural networks for developing an alternative integration scheme of low cost Microelectromechanical System (MEMS) Inertial Navigation System (INS) and Global Positioning System (GPS) for vehicular navigation applications. The primary objective is to overcome the limitations of current INS/GPS integration scheme and improve the positioning accuracy during GPS signal blockages. The results presented in this article indicated that the proposed technique was able to provide 47% and 78% improvement in terms of positioning accuracy during GPS signal blockages.

Jul 2005 | Comments Off on Using positional and navigational technology in Australia

While digital techniques were introduced to map production in the 1970’s, the driver for utilising digital tools to manage this wide range of activities was the land administration functions of the six states and two territories. Developed in concert by the legal and surveying professions, these state and territory based land administrations functions led to digital land valuation systems as early as 1968 in South Australia. Building upon such initiatives; government guaranteed computerised land registration and automated valuation systems have been built.
