Capturing the spatio-temporal behavior of real traÆc data

TraÆc, like disk and memory accesses, typically exhibits burstiness, temporal locality and spatial locality. There is much recent ground-breaking work on temporal modeling (self-similarity etc), on disk and web traÆc, with several statistical models that generate realistic series of timestamps. However, no work generates realistic traces for both time and location (eg., block-id). In fact, exce...

Spatio-Temporal Tensor Completion for Estimating Missing Internet Traffic Data

Network traffic data consists of Traffic Matrix (TM), which represents the volumes of traffic between Origin and Destination (OD) pairs in the network. It is a key input parameter of network engineering tasks. However, direct measurement of the OD pairs traffic is usually not feasible. Even good traffic measurement systems can suffer from errors, missing data. So obtaining the ODs traffic preci...

Spatio-temporal traffic video data archiving and retrieval system

This paper presents a transportation spatio-temporal system that efficiently converts traffic video data into vehicular motion information in spatio-temporal databases for a variety of transportation applications. The proposed transportation spatio-temporal system interpolates the vehicle trajectory data (i.e., time, location, and speed), which are extracted from video, and integrates them with...
