無人自動駕駛車之「意圖傳達」設計

Abstract

本論文研究目的，為設計一個無人自動駕車與用路人的溝通方式，讓用路人瞭解無人自動駕駛車的狀態，提升交通活動效率與安全。該研究先透由質性研究，從人類駕駛與其它人類用路人互動中，找出溝通的意圖種類、使用的信號方式、選擇信號的環境變因。接下來設計意圖與信號對映方式，使用量化研究，把意圖與信號對映的設計透由影片播放，與問卷答題的方式來實行群眾設計，找出用路人對該意圖最佳的認知信號。 最後本研究提出一個「意圖-變因-信號」可擴展資訊架構，把意圖至信號選擇的決策方式系統化，可以讓未來的研究者可以在發展新的意圖與信號使用時，可以根據這樣的指導原則去延伸使用。

This study aims to provide a design guideline for communication between autonomous vehicles and road users. The guideline can help road users better realize the intents of autonomous vehicles and hence improve the efficiency and safety of road activities. The research was conducted in two parts. In the first stage, we interviewed human drivers to analyze the relationship between the choice of car signals and in-depth intents. The resulting factors lead to a series of intent-signal design, which was evaluated with a large-scale survey study in the second phase. With this Intent-Factor-Signal approach, we propose an extensible architecture of autonomous vehicle signal design. Vehicle designers can choose the signal based on the intent systematically by following the guideline. The research framework also serves as a guide on how to organize and facilitate future research on communication between autonomous vehicles and road users.
