Navigational Rule Derivation: An algorithm to determine the effect of traffic signs on road networks
(2016-11-17)[Abstract] In this paper we present an algorithm to build a road network map enriched with traffic rules such as one-way streets and forbidden turns, based on the interpretation of already detected and classified traffic ... -
A New Method to Index and Store Spatio-Temporal Data
(2016-11-16)[Abstract] We propose a data structure that stores, in a compressed way, object trajectories, which at the same time, allow to efficiently response queries without the need to decompress the data. We use a data structure, ... -
Grammar compressed sequences with rank/select support
(Elsevier BV, 2016-10-14)[Abstract] Sequence representations supporting not only direct access to their symbols, but also rank/select operations, are a fundamental building block in many compressed data structures. Several recent applications need ... -
Compact Trip Representation over Networks
(Springer, 2016-09-21)[Abstract] We present a new Compact Trip Representation ( CTRCTR ) that allows us to manage users’ trips (moving objects) over networks. These could be public transportation networks (buses, subway, trains, and so on) where ... -
GraCT: A Grammar Based Compressed Representation of Trajectories
(Springer, 2016-09-21)[Abstract] We present a compressed data structure to store free trajectories of moving objects (ships over the sea, for example) allowing spatio-temporal queries. Our method, GraCT, uses a k2k2 -tree to store the absolute ...
