高速公路異常狀況偵測方法之研究

無線網路通訊的進步及普及，車用電子通訊產品的多樣性也逐年快速的成長，其價格也隨著成長而越來越低，相對應的車載間通訊協定亦順應而生。許多提醒交通意外的研究大多著重於減少廣播風暴及強化傳輸路徑。由於GPS的普及，上述的研究會利用GPS來達成他們的目標，但偵測道路異常狀況的問題卻一直尚未被提出，而本篇論文就是探討此問題。在本篇論文中，我們假設每輛車皆配備有GPS且會定期回報他們的GPS座標及車速。我們提出的系統可以利用這些資料來偵測道路壅塞、道路施工及道路回堵的車況。同時也提供Android上的使用者介面來提醒駕駛人道路異常狀況。另外也開發了管理者介面協助全國交通資訊中心藉由廣播來提醒駕駛人道路異常狀況。

As wireless access techniques are being improved and popularized, diverse vehicular products of electronic communication are increasing sharply year after year. Therefore, the price of products is decreasing along with the growth of them. Accordingly, there are a lot of researches on telematics with alerting cars to traffic accidents. Most of them have focused on how to reduce broadcast storm of alerting messages and how to efficiently route alerting messages. Due to the wide-spreading of GPS (Global Positioning System), there is a trend that using GPS to achieve the above objective. The problem of detecting abnormal traffic conditions has been ignored. In this paper, this problem is studied. In this paper, we assume a car with GPS will periodically report its GPS coordinates and velocity. With this information, the proposed system can detect traffic jam, road construction, and congestion at interchanges. A user interface has been developed in Android to alert drivers to the above abnormal traffic conditions. Another management interface for National Freeway Bureau has also been developed to help broadcast the abnormal traffic conditions to drivers.
