Trajectory Search by Region

computer science and Electronics and Communication Engineering

With the increasing availability of moving-object tracking data, trajectory search is increasingly important. We propose and investigate a novel query type named trajectory search by regions of interest (TSR query). Given an argument set of trajectories, a TSR query takes a set of regions of interest as a parameter and returns the trajectory in the argument set with the highest spatial density correlation to the query regions. This type of query is useful in many popular applications such as trip planning and recommendation, and location based services in general. TSR query processing faces three challenges: how to model the spatial-density correlation between query regions and data trajectories, how to effectively prune the search space, and how to effectively schedule multiple so-called query sources. To tackle these challenges, a series of new metrics are defined to model spatial-density correlations. An efficient trajectory search algorithm is developed that exploits upper and lower bounds to prune the search space and that adopts a query-source selection strategy, as well as integrates a heuristic search strategy based on priority ranking to schedule multiple query sources. “TSR Query” Application is used to search the famous places in the cities which we want to visit.in this application having all cities in India and famous place in the relevant cities. The user can choose the cities and view the famous places in the cities and view the reviews and ratings to plan the tour, the user view the current places in the map and view the trajectories in the map for riding by the road. The existing user information is useful for the places to visit and know the weather and road condition of the places
