ملخص المقالة :
در اين مقاله، يك الگوريتم جديد رديابي بالا به پايين بر اساس يادگيري مسير حركت وسايل نقليه ارائه مي‌شود. به اين منظور يك ماتريس گذر مراكز، CTM، كه يك پايگاه دادة مكاني-زماني جديد است، پيشنهاد مي‌شود. براي ايجاد اين ماتريس ابتدا با خوشه‌بندي فازي روي مسيرهاي حركت وسايل نقليه بدست آمده، مراكزي بدست مي‌آيد سپس ماتريس CTM روي اين مراكز تعريف مي‌شود. عنصر i, j ام اين ماتريس بيان كنندة آن است كه شيئي در دو فريم متوالي از مركز i به مركز j گذر كرده است كه تكميل درايه‌هاي اين ماتريس با رديابي چند شيئي وسايل نقليه به مرور انجام مي‌شود. ماتريس CTM در افزايش سرعت همگرايي پيش‌بين RLS و جستجوي بهتر موقعيت وسيلة نقليه موثر است. الگوريتم رديابي پيشنهادي در مكانهاي مختلفي در صحنة ترافيك آزمون شد كه نتايج حاصله حاكي از افزايش كارايي در الگوريتم رديابي است.
