一般的車內導引資訊主要係提供所計算出來之最短路徑予以駕駛人，但對於駕駛人來說此路徑不一定能夠符合其認路時路徑形成的原則。因此為了了解此研究課題，本研究採用附有認路元素之路徑導引資訊方式來進行實驗，透過實驗之反應對資料蒐集進行分析與歸納，以進一步的探討基於認路元素之路徑導引資訊對於逐點動態路徑選擇行為之影響。 本研究之內容主要可分為二部份，第一部份是認路特性的調查分析，利用結構化問卷包括了駕駛人特性、認知地圖(利用手繪簡圖)、情境問項、導引資訊系統所標示之認路元素(如：地標)特性的認知及導引資訊的使用與否對駕駛人認路方式的影響。第二部份則是分為兩階段之動態控制模擬實驗，第一階段主要目的則是觀察並蒐集駕駛者在一般導引資訊提供下，個人的逐點動態路徑決策行為作為對照組，第二階段之實驗目的則是提供符合駕駛者在附有認路元素(如：地標)之導引資訊下其逐點動態路徑決策行為做為實驗組，並觀察受測者在兩階段控制實驗中決策點遵循率變化情形。 A concept of way-finding based in-vehicle route guidance has been proposed, where additional landmarks and/or other elements of reference to supplement the route recognition along the recommend route to complete the trip appeared on the guidance map. In this paper, in addition to a preliminary survey to collect the individual elements of cognitive map (via sketch map technique) or way-finding, a two-stage comprehensive controlled experiment has been conducted where selected subjects will be examined in two comparative laboratory simulation scenarios of their dynamic node-to-node decisions. The first scenario is to provide and update the driver the best (shortest) possible route at each decision node along entire journey as conventional fashion. In the second stage, each individual experiment subject was supplied with the routing strategy enhanced with elements of route recognition/way-finding at various strategic location based on the results from the preliminary survey. Finally, compliance record was compared between these two contrasted scenarios to investigate the effect of different routing strategies. The results have demonstrated statistically significant improvement of compliance rate over conventionalrouting strategy for landmark-enhanced strategy.
