![]() ![]() It is critical to investigate the impact of infrastructure building or expansion on the overall walk and bicycle mode usage prior to making investment choices utilizing public tax money. Building a community with amenable walk and bicycle facilities asks for smart planning and investments. = ,Īctive transportation modes-walk and bicycle-are central for low carbon transport, healthy living, and complete streets initiative. Finally, the elasticity of social influence was found to range locally from about 0.5% to 1.0%. Observed ownership share closely matched predicted local-level equilibrium in some metropolitan areas but was unable to achieve expected prediction rate within confidence intervals. The behavioral hypothesis of positive preference change due to more » information transfer was confirmed. Our results showed that more informed households had a greater chance of owning a bike due to preference changes with less sensitivity to smaller home footprints and limited incomes. A case study to study social influence in bicycle ownership in the United States is presented. Additionally, a two-stage control function is developed to obtain consistent parameter estimates in the presence of an endogenous class membership model covariate that is correlated with choice model unobservables. ![]() The informational conformity model can represent non-linear elasticity behavior unlike the direct-benefit formulation. Social influence elasticity is derived for both models types. Equilibrium properties are derived for this model showing the possibility of multiple equilibria but under different conditions than the direct-benefit formulations. Membership into the more informed class causes changes in the preferences of those individuals thus making adoption more attractive. Moreover, class membership depends on the proportion of group members who adopt a behavior. Indirect effects have seen limited development, but this paper presents a latent class discrete choice model of an indirect informational conformity hypothesis. The current state-of-the-art in social influence models of travel behavior is conformity models with direct benefit social influence effects. ![]()
