| 中文摘要 | 本研究針對Boyce等人以最佳化控制理論建構的瞬時性動態用路人最佳化交通量指派模型及其演算法加以詳細探討,為了進一步的瞭解瞬時性動態用路人最佳化的狀態,故首先對瞬時性動態用路人之路徑選擇行為進行模擬分析。其後,再對Boyce等人發展之瞬時性動態用路人最佳化模型提出修正式演算法並加以測試與分析,此修正式演算法乃重新推導Frank-Wolfe法中的線性子問題進而修改演算過程,使得修正後的演算過程更符合瞬時性動態用路人之路徑選擇行為的假設,且可減少運算時所需的計算機記憶體空間。最後並對未來應繼續進行的研究方向提出建議。 |
| 英文摘要 | Recently, an instantaneous dynamic user optimal model and the associated solution algorithm were proposed by Boyce et al. To make its practical implementation possible, many issues are yet to be clarified and explored. This study first performs a flow-based simulation model to gain insights about how drivers behave with instantaneous traffic information. Along the same line of Boyce et al's solution algorithm, a modified version with many advantages from the viewpoint of memory requirement and computational efficiency is then proposed for solving the discretized instantaneous dynamic user optimal model. The rationality of the proposed solution algorithm is justified with a numerical example by showing that the resultant flow pattern is coincident with the drivers' behavior. |
