Fine-grained OD estimation with automated zoning and sparsity regularisation

Menon, Aditya; Cai, Chen; Wang, Weihong; Wen, Tao; Chen, Fang


Given a road network, a fundamental object of interest is the matrix of origin destination (OD) flows. Estimation of this matrix involves at least three sub-problems: (i) determining a suitable set of traffic analysis zones, (ii) the formulation of an optimisation problem to determine the OD matrix, and (iii) a means of evaluating a candidate estimate of the OD matrix. This paper describes a means of addressing each of these concerns. We propose to automatically uncover a suitable set of...[Show more]
