We consider the problem of finding the closest point of interest in road networks where the travel time along each edge is a function of the departure time and the service time of the facilities are taken into consideration. More specifically, our query aims to find the point of interest (e.g., a museum) in which the user can be served in the minimum amount(More)
We consider the problem of finding the k nearest points of interest from a given location in time-dependent road networks, i.e., One where travel time along each edge is a function of the departure time, and where the operating times of the points of interest are also taken into consideration. More specifically, we address the following query: find the k(More)
In this paper we present an algorithm for optimal processing of time-dependent sequenced route queries in road networks, i.e., given a road network where the travel time over an edge is time-dependent and a given ordered list of categories of interest, we find the fastest route between an origin and destination that passes through a sequence of points of(More)
Advancements in mobile computing techniques along with the pervasiveness of location-based services have generated a great amount of trajectory data. These data can be used for various data analysis purposes such as traffic flow analysis, infrastructure planning and understanding of human behavior. However, publishing this amount of trajectory data may lead(More)
1 Introdução A economia brasileira está em profundas transformações, renovando conceitos, estratégias e alinhando-se às mudanças globais a fim de se tornar mais competitiva e especializada. Devido ao Brasil seguir em ascendente crescimento, beneficiado pela estabilidade econômica que já fora posta à prova durante a última crise financeira mundial, as(More)
