  • Alonso's General Theory of Movement: Advances in Spatial Interaction Modeling, de Vries, Nijkamp and Rietveld. The changed notation can be reverted by applying the following rewrite rules:
    T_ij → M_ij; F_ij → t_ij; O_i → M_ix; D_j → M_xj; A_i → D_i⁻¹; B_j → C_j⁻¹; V_i → v_i; W_j → w_j; c_ij → d_ij; γ₁ → γ
  • For the theory in summary form, with the gravity model and Wilson's family of constrained models leading up to the GTM, see Spatial Interaction Models in the Accessibility Modelling wiki. That page also explains what the interaction section does and does not cover: with β_j fixed at 1.0, the elasticity α spans Wilson's unconstrained and production constrained models, but not the attraction constrained or doubly constrained ones.
• more basic (and contrived) examples can be found in the GeoDMS test project, more specifically: in the Network section of: operator/cfg/operator.dms .
