Allocation of Link Flow Detectors for Origin-Destination Matrix Estimation - A Comparative Study

The Origin–Destination Matrix Estimation Problem — Analysis and Computations

For most kind of analyses in the field of traffic planning, there is a need for origin– destination (OD) matrices, which specify the travel demands between the origin and destination nodes in the network. This thesis concerns the OD-matrix estimation problem, that is, the calculation of OD-matrices using observed link flows. Both time-independent and time-dependent models are considered, and we...

Network Origin-Destination Demand Estimation using Limited Link Traffic Counts: Strategic Deployment of Vehicle Detectors through an Integrated Corridor Management Framework

Compressive Origin-Destination Matrix Estimation

The paper presents an approach to estimate OriginDestination (OD) flows and their path splits, based on traffic counts on links in the network. The approach called Compressive Origin-Destination Estimation (CODE) is inspired by Compressive Sensing (CS) techniques. Even though the estimation problem is underdetermined, CODE recovers the unknown variables exactly when the number of alternative pa...

A robust framework for the estimation of dynamic OD trip matrices for reliable traffic management

Origin-Destination (OD) trip matrices describe the patterns of traffic behavior across the network and play a key role as primary data input to many traffic models. OD matrices are a critical requirement, either in static or dynamic models for traffic assignment. However, OD matrices are not yet directly observable; thus, the current practice consists of adjusting an initial or a priori matrix ...

Capacitated Single Allocation P-Hub Covering Problem in Multi-modal Network Using Tabu Search

The goals of hub location problems are finding the location of hub facilities and determining the allocation of non-hub nodes to these located hubs. In this work, we discuss the multi-modal single allocation capacitated p-hub covering problem over fully interconnected hub networks. Therefore, we provide a formulation to this end. The purpose of our model is to find the location of hubs and the ...
