Theoretical Bounds of Congestion-Pricing Efficiency for a Continuum Transportation System

Consider a city of an arbitrary shape where users are distributed continuously over the city region. Within this region, the road network is dense and can be represented as a continuum: user patronize a two-dimensional continuum network to the central business district (CBD). A congestion-pricing technique is applied to this continuum transportation system to maximize its total social welfare. This paper presents the theoretical bounds for the efficiency of this congestion-pricing scheme for both fixed and elastic demand cases. The ratio of total costs and total social welfare between the system-optimal and user-optimal travel patters are take as measures of efficiency in the fixed and elastic demand cases, respectively. With a better understanding of the efficiency of congestion-pricing, traffic planners can better comprehend the likely benefit that is obtainable from a congestion-pricing scheme.
