Density and flow reconstruction in urban traffic networks using heterogeneous data sources

In this paper, we consider the problem of joint reconstruction of flow and density in a urban traffic network using heterogeneous sources of information. The traffic net- work is modeled within the framework of macroscopic traffic models, where we …

Thesis - Traffic state estimation and prediction in freeways and urban networks

Centralization of work, population and economic growth alongside continued urbanization are the main causes of congestion. As cities strive to update or expand aging infrastructure, the application of big data, new models and analytics to better …

A real time forecasting tool for dynamic travel time from clustered time series

This paper addresses the problem of dynamic travel time (DTT) forecasting within highway traffic networks using speed measurements. Definitions, computational details and properties in the construction of DTT are provided. DTT is dynamically …

Travel time forecasting from clustered time series via optimal fusion strategy

This paper addresses the problem of travel time forecasting within a highway. Several measurements are cap- tured describing travel times for multiple origin-destination (OD) pairs. A network model is then proposed to infer travel time between origin …
