Co-Clustering Network-Constrained Trajectory Data

Recently, clustering moving object trajectories kept gaining interest from both the data mining and machine learning communities. This problem, however, was studied mainly and extensively in the setting where moving objects can move freely on the euclidean space. In this paper, we study the problem of clustering trajectories of vehicles whose movement is restricted by the underlying road networ...

Graph-Based Approaches to Clustering Network-Constrained Trajectory Data

Clustering trajectory data attracted considerable attention in the last few years. Most of prior work assumed that moving objects can move freely in an euclidean space and did not consider the eventual presence of an underlying road network and its influence on evaluating the similarity between trajectories. In this paper, we present an approach to clustering such network-constrained trajectory...

Trajectory Regression on Road Networks

This paper addresses the task of trajectory cost prediction, a new learning task for trajectories. The goal of this task is to predict the cost for an arbitrary (possibly unknown) trajectory, based on a set of previous trajectory-cost pairs. A typical example of this task is travel-time prediction on road networks. The main technical challenge here is to infer the costs of trajectories includin...

Updating of Road Network Databases: Spatio-Temporal Trajectory Grouping Using Snap-Drift Neural Network

Research towards an innovative solution to the problem of automated updating of road network databases is presented. It moves away from existing methods where vendors of road network databases either go through the time consuming and logistically challenging process of driving along roads to register changes or use update methods that rely on remote sensing images. The solution presented here w...

NNCluster: An Efficient Clustering Algorithm for Road Network Trajectories

With the advent of ubiquitous computing, we can easily acquire the locations of moving objects. This paper studies the clustering problem for trajectory data which are constrained by the road network. While many trajectory clustering algorithms have been proposed, they do not consider the spatial proximity over the road network. For such trajectory data, we propose a new distance measure that r...
