Traffic flow data is a decisive element in transportation planning and traffic management.
Over time, traffic sensors have been recognized as sources of such data. Despite their …

A state‐of‐the‐art review of flow observability, estimation, and prediction problems in traffic
networks is performed. Since mathematical optimization provides a general framework for all …

Network planning and traffic flow optimization require the acquisition and analysis of large
quantities of data such as the network topology, its traffic flow data, vehicle fleet composition …

The full link flow observability problem is to identify the minimum set of traffic sensors to be
installed in links in a road traffic network. The sensors are used to both monitor the flow of …

The quality of information on a network is crucial for different transportation planning and
management applications. Problems focusing on where to strategically extract this …

The hourly traffic flows between various origin–destination (OD) pairs fluctuate by time of
day and day of the year. These multi-period OD demands are statistically correlated with one …

The problem of optimally locating fixed sensors on a traffic network infrastructure has been
object of growing interest in the past few years. Sensor location decisions models differ from …

In this paper, we deal with the observability problem in traffic networks and the optimal
location of counting and scanning devices. After explaining what we mean by observability …

The concepts of hole, cycle added link and non-planar hole-generated network are
introduced for the first time and used to determine (a) the immediate solution of the node …

This research proposes a novel single-level approach to traffic counts-based OD estimation
using observed turning proportions and partial OD flows. The key idea is to relax the need …
