On crowdsensed data acquisition using multi-dimensional point processes

Karl Aberer, Saket Sathe

Crowdsensing applications are increasing at a tremendous rate. In crowdsensing, mobile sensors (humans, vehicle-mounted sensors, etc.) generate streams of information that is used for inferring high-level phenomena of interest (e.g, traffic jams, air pollu ...

Traffic modeling, forecasting and assignment in large-scale networks

Mehmet Yildirimoglu

Today, the development and evaluation of traffic management strategies heavily relies on microscopic traffic simulation models. In case detailed input (i.e. od matrix, signal timings, etc.) is extracted and incorporated in these simulators, they can provid ...

Dynamics of heterogeneity in urban networks: aggregated traffic modeling and hierarchical control

Nikolaos Geroliminis, Mohsen Ramezani Ghalenoei, Jack Haddad

Real traffic data and simulation analysis reveal that for some urban networks a well-defined Macroscopic Fundamental Diagram (MFD) exists, which provides a unimodal and low-scatter relationship between the network vehicle density and outflow. Recent studie ...

A Poisson Hidden Markov Model for Multiview Video Traffic

Pascal Frossard, Lorenzo Rossi

Multiview video has recently emerged as a means to improve user experience in novel multimedia services. We propose a new stochastic model to characterize the traffic generated by a Multiview Video Coding (MVC) variable bit-rate source. To this aim, we res ...

Investigating empirical implications of hysteresis in day-to-day travel time variability

Nikolaos Geroliminis, Mehmet Yildirimoglu, Ypatia Stefania Limniati

Day-to-day travel time variability plays a significant role in travel time reliability. Nowadays, travelers not only seek to minimize their travel time on average, but also value its variation. The variation in the mean and the variance of travel time (acr ...

An Underlying Asymmetry within Particle-size Segregation

Christophe Ancey, Nicolas Andreini, Gaël Epely Chauvin, Kasper van der Vaart

We experimentally study particle scale dynamics during segregation of a bidisperse mixture under oscillatory shear. Large and small particles display an underlying asymmetry that is dependent on the local particle concentration, with small particles segreg ...

Traffic modeling, estimation and control for large-scale congested urban networks

Mohsen Ramezani Ghalenoei

Part I of the thesis investigates novel urban traffic state estimation methods utilizing probe vehicle data. Chapter 2 proposes a method to integrate the collective effect of dispersed probe data with traffic kinematic wave theory and data mining technique ...

Control concepts for facilitating motorway on-ramp merging using intelligent vehicles

Riccardo Scarinci

Congestion at motorway junctions is a traffic phenomenon that degrades operation of infrastructure and can lead to breakdown of traffic flow and associated reduction in capacity. Advanced communication technologies open new possibilities to prevent or at l ...
