Nowadays, mobile devices are already seen everywhere in life, which makes the application of vehicle navigation more and more widely. The traditional turn-by-turn navigation does the path planning just based on the characteristics of the roads themselves, and then gives mechanized steering instructions at each corner. For those roads people are familiar with in this route, path descriptions which provide detailed route description information, will become redundant and verbose. In this paper, we study a Personalized Route Description system dubbed PerRD - with which the goal is to generate more customized and intuitive route descriptions based on user generated content. The goal is to optimize a given route description with paths which users know well, which makes the route more consistent with users' driving habits, and to create a concise and meaningful route descriptions with POIs and street names.
