The Most Preferred Route of the Car Navigation System: A Systems Engineering Approach

Abstract

The typical route planning of on-board car navigation systems (CNS) attempts to find the shortest route without considering users preferences and driving contexts. However it is more effective for a user to find the most preferred route rather than the shortest one. We propose a systems engineering approach for finding the most preferred route by considering and tracking the requirements of CNS route planning from the business point of view. Our approach consists of 4 baselines: customer baseline, system baseline component baseline, and design baseline. The architecture of a route planning engine is suggested according to the baselines.
