DATA-ORIENTED ALGORITHM FOR ROUTE CHOICE SET GENERATION IN A METROPOLITAN AREA WITH MOBILE PHONE GPS DATA

摘要: Nowadays, for the estimation of traffic demand or people flow, modelling route choice activity in road networks is an important task and many algorithms have been developed to generate sets. However, developing algorithm based on a small amount data that can be applied generally within metropolitan area difficult. This because characteristics vary widely. On other hand, recently, collection movement has lately become much easier, especially through mobile phones. Lately, most phones include GPS functionality. Given this background, we propose data-oriented sets using phone data. contain number measurement errors; hence, they must adjusted account these errors before use advanced analysis. time-consuming expensive, enormous daily obtained. Hence, objective study develop easily manage Specifically, at first from all are selected by calculating speed. Next, nearest roads network location count such each road. Then An GSP (Gateway Shortest Path) proposed, which searches shortest path given gateway. In proposed algorithm, utilization volume calculated large as Thus, trends real generated. To evaluate method, 0.7 million year Japan DRM (Digital Road Map) used. one detailed Japan. Route generated cover rate under evaluation calculated. As result, generation cleaning process work well huge variety routes high potential used world
