Mathematical model for modulus of geometric aspects was solved to evaluate ease with which vehicular traffic traverses highway section with particular combination of geometric features; these geometric moduli are predicated on approach speed of traffic and on speed reduction produced by design elements; design variables evaluated for two-lane highways were degree of curve, gradient, minimum stopping sight distance, and lane width.
