Through an extended numerical example, this paper develops a diagrammatic
analysis of steady-state parking and traffic congestion in an isotropic downtown and
provides systematic policy analysis. Unlike our previous work, the model incorporates
curbside parking, garage parking, and price-sensitive travel demand in a unified setting.
We examine the deadweight loss associated with underpriced curbside parking, as well
as first- and second-best curbside parking capacities. We also explore the transient
dynamics and stability of various downtown traffic equilibria.
