Traffic congestion is a serious problem that is only expected to get worse in the future. Statistics shows that half of traffic congestion is caused by temporary disruptions like accidents. These events have dramatic impact on road network availability and cause huge delays for commuters. Also, they are usually unexpected ...

Distributed spatial simulations commonly employ Bulk Synchronous Parallel model (BSP) implementation. However, implementations using BSP are usually fraught with the straggler problem, where the delay of any worker slows down the entire system. Random stragglers commonly occur due to many reasons: imbalanced workload, operating system scheduling, or communication delays. The ...

Microscopic traffic simulators are important tools for studying transportation systems as they describe the evolution of traffic to the highest level of detail. A major challenge to microscopic simulators is the slow simulation speed due to the complexity of traffic models. We have developed the Scalable Microscopic Adaptive Road Traffic ...

Route planning in current route guidance systems is primarily based on the shortest path strategy (e.g., suggesting a path that minimizes the travel distance between source and destination) for an individual driver. A drawback of such an approach is that there is a high probability that many drivers, who share ...

Counts of objects are important for big data analytics. However, spatial objects do not work well with counts. We present the latest developments on distinct counting problem. In particular, we explain Euler Histograms, which are a category of spatial data structures that address the distinct counting challenges. Euler histograms support ...

This work addresses the problem of aggregation of trajectories data. Specifically, we propose a tree-based data structure for counting vehicle trajectories by mapping them into a set of spatial histograms with different granularities. We also present an approach for processing spatio-temporal range queries by aggregating the histograms in the query ...

Privacy concerns can be a major barrier to collecting aggregate data from the public. Recent research proposes negative surveys that collect negative data, which is complementary to the true data. This opens a new direction for privacy-aware data collection. However, the existing approach cannot avoid certain errors when applied to ...

Traffic-monitoring systems (TMSs) are vital for safety and traffic optimization. However, these systems may compromise the privacy of drivers once they track the position of each driver with a high degree of temporal precision. In this paper, we argue that aggregated data can protect location privacy while providing accurate information ...

Companies, government agencies, and other organizations are making their data available to the world over the Internet. They often use large online relational tables for this purpose. Users query such tables with front-ends that typically use menus or form fillin interfaces, but these interfaces rarely give users information about the ...
