ESTIMATING ORIGIN-DESTINATION MATRICES FROM TRAFFIC COUNTS: A SIMPLE LINEAR INTERCITY MODEL FOR QUEBEC
Mji Gaudry, L. Lamarre · Logistics and transportation review · 1978
This paper presents a linear model to estimate an intercity origin-destination matrix from volume counts on network links. It is argued that the use of a single impedance term in the assignment procedure and the taking into account of heteroscedasticity of the residuals circumvent some of the difficulties presented by o-d estimation problems. Indirect evidence from residuals of the linear model and from A gravity format suggest that significant non-linearities are present in the data set and could be isolated if the present state of techniques permitted to distinguish between the functional form of a model and heteroscedasticity of the residuals.(a) (TRRL) terminology. The guide is the first of a series of four consecutive guides to information searching on roads and traffic. The other guides describe secondary sources of information, original publications, and producers of information on roads and traffic.
