摘要

車載網路在道路安全和其他很多商業用途上非常具有實用性。因此我們的作法是，實現一套取得任意位置的即時交通資訊系統。我們將自行設計我們所需要使用到的功能，構建我們的GIS數字地圖，並在VANET實驗及許多應用中使用 。
在資料庫的設計上，我們使用道路運輸研究所的數字地圖，交通和通信部向發展我們的地理信息系統數據庫。我們的方法可以提供駕駛當前位置於畫面的地圖上，作為行車導航用，並用鏡頭錄製行車影像。同時在背景對錄製資料後做處理，並依照封包傳輸的特定格式（例如當前錄製位置.時間 等）做命名。在client部份 平板負責的動作為結合行車紀錄器與行車導航及處理封包運算的角色，一方面可以提供駕駛顯示當前位置於畫面的地圖上，達到行車導航功能，並用鏡頭錄製行車影像。
同時在背景對錄製資料後做處理，並依照封包傳輸的特定格式（例如當前錄製位置.時間 等）做命名;另一方面，當需要查詢某地的即時路況時，讓使用者查詢目的地路口的地理座標，對目標發送請求即時路況資源（影像或圖片）。

Vehicular ad hoc networks have been envisioned to be useful in road safety and many commercial applications.
We design our own functions that we need and construct our GIS digital map which is used in a lot of VANET experiments.
In the database design, we use the digital road map of the Institute of Transportation, Ministry Of Transportation And Communications to develop our GIS database.
Driver not only use the Eeepad as GPS navigation software but also use it to record a webcam video.
At the same time, Eeepad also names video data according to a specific format such as current location or date in the background.
On the client side, Eeepad is responsible for integration of event data recorder, GPS navigation software, and operation of packets computation.
On one hand, driver not only use the Eeepad as GPS navigation software but also use it to record a webcam video.
At the same time, Eeepad also names video data according to a specific format such as current location or date in the background.
On the other hand, people can get Latitude and longitude data from pad and information(photo or video) about real-time traffic from other user when they need to look up instantaneous traffic condition.
