W" subkey="e">find that our approach produces improved model fit and higher likelihood values. The model accounts for spatial dependence</field> <field key="in" subkey="t">he origin-destination flows by introducing a spatial connectivity matrix that allows for three types of spatial dependence in</field> <field key="the" subkey="">origins to destinations flows. We modify this origin-destination connectivity structure that was introduced by LeSage and</field> <field key="Pac" subkey="e">(2005) to include information regarding the presence or absence of a major highway/train corridor that passesthrough the</field> <field key="reg" subkey="i">ons. Empirical estimates indicate that the strongest spatial autoregressive effects arise when both origin and destination</field> <field key="reg" subkey="i">ons have neighboring regions located on the highway network. Our approach provides a formal spatial econometric methodology</field> <field key="tha" subkey="t">can easily incorporate network connectivity information in spatial autoregressive models.;</field> </SEQUENTIAL> </section> Servertime: 0.61 sec | Clienttime:
