    摘要: 隨著近年物聯網、5G網路應用及深度學習等技術的發展。智慧城市的發展也逐漸受到重視，其中智慧交通更是政府主要的推廣的領域。對於停車位搜尋問題，目前最常見的做法是在每個停車位設置感測器，透過提供駕駛即時的停車位資訊令駕駛能找到合適的停車位，也因此近年停車位搜尋問題的相關研究多半著重在改善對於停車空位的偵測能力。雖然直接提供每個固定停車位的即時資訊，可以為駕駛選擇行駛路線提供幫助，但在使用者驅車前往該停車空位的過程，停車空位仍有先被其他駕駛使用的可能性。這會導致使用者必須在途中重新判斷並選擇行駛路線，而無法在原先估計的地點順利停車，形成欲透過提供停車位資訊間接解決停車問題時的盲點。為解決此問題，停車位搜尋問題的另一種研究方向是將重心放在找到合適的停車路徑而非鎖定特定的停車空位上。透過預測停車空位存在的機率，為使用者導航較高機率的停車行駛路線，進而減少車輛因尋找停車位導致徘徊的行車時間。
    由於目前台灣的實體環境適用於停車空位統計的相關資料較少，且設置大量相關感測器的成本高昂，短期難以實現大規模的建設。本研究擬以需要設置較少感測器的深度強化學習方法，Deep Q-Learning解決停車位搜尋問題，並加入及LSTM(Long Short-Term Memory)及GRU(Gated Recurrent Unit)神經網路模型提升深度強化學習模型中對於Q值估算的精確度。最終透過深度強化學習模型引導車輛行駛停車路線，達到降低停車所需行駛時間的目的。而缺乏適用於研究問題統計資料的問題，本研究將透過SUMO模擬器(Simulation of Urban MObility)，根據整體的停車頻率及車流量產生擬真的車流環境，以此作為學習模型的訓練資料及實驗資料。模擬資料將隨機產生一般車流與停車車流。一般車流是指目的地在停車範圍外不會停留於停車範圍內的車流，這類車流將以最短路徑在模擬環境中行經停車範圍。停車車流則是目的地設定在停車範圍內的車流，用以模擬實際車流環境中可能會在目標車輛搜尋停車路徑中停車的其他車輛。本研究旨在以模擬車流資料驗證使用深度強化學習解決停車位搜尋問題的有效性，並比較強化學習及深度學習方法在解決停車位搜尋問題的表現，評估不同深度學習方法在進一步解決停車問題上的效益。
