商品描述
This book presents the index and query techniques on road network and moving objects which are limited to road network. Here, the road network of non-Euclidean space has its unique characteristics such that two moving objects may be very close in a straight line distance. The index used in two-dimensional Euclidean space is not always appropriate for moving objects on road network. Therefore, the index structure needs to be improved in order to obtain suitable indexing methods, explore the shortest path and acquire nearest neighbor query and aggregation query methods under the new index structures.
Chapter 1 of this book introduces the present situation of intelligent traffic and index in road network, Chapter 2 introduces the relevant existing spatial indexing methods. Chapter 3-5 focus on several issues of road network and query, they involves: traffic road network models (see Chapter 3), index structures (see Chapter 4) and aggregate query methods (see Chapter 5). Finally, in Chapter 6, the book briefly describes the applications and the development of intelligent transportation in the future.商品描述(中文翻譯)
本書介紹了針對道路網路和移動物體的索引與查詢技術,這些技術僅限於道路網路。在此,非歐幾里得空間的道路網路具有其獨特的特性,兩個移動物體在直線距離上可能非常接近。在二維歐幾里得空間中使用的索引不一定適用於道路網路上的移動物體。因此,索引結構需要改進,以獲得合適的索引方法,探索最短路徑,並在新的索引結構下獲取最近鄰查詢和聚合查詢方法。
本書的第一章介紹了智能交通和道路網路中的索引現狀,第二章介紹了相關的現有空間索引方法。第三至第五章專注於道路網路和查詢的幾個問題,涉及:交通道路網路模型(見第三章)、索引結構(見第四章)和聚合查詢方法(見第五章)。最後,在第六章中,本書簡要描述了智能交通在未來的應用和發展。
