Congestion, ramp metering and tolls.
The cell transmission model of a freeway is used to compare four congestion-reducing schemes: (R) ramp control only; (T) one lane is tolled and ramps are uncontrolled; (B) bottlenecks are tolled and ramps are uncontrolled; and (RB) ramps are controlled and bottlenecks are tolled. In the base case, ramps are uncontrolled and there are no tolls. It is found that (T) is inefficient and may leave a...
متن کاملManipulable Congestion Tolls
The recent literature on congestion pricing with large agents contains a remarkable inconsistency: though agents are large enough to recognize self-imposed congestion and exert market power over prices, they do not take into account the impact of their own actions on the magnitude of congestion tolls. When large agents are confronted with tolls derived under this parametric assumption but under...
متن کاملModeling Road Traffic Congestion by Quasi-Dynamic Traffic Assignment
The paper deals with simulation of congested road networks through dynamic traffic assignment models and presents a new quasi-dynamic traffic assignment model that improves realism and effectiveness of both usual static traffic assignment models and other quasi-dynamic models recently introduced in the literature, as it simulates flow progression onto the network by moving link flows according ...
متن کاملFreeway congestion, ramp metering, and tolls
California freeway travelers suffer large and variable congestion delay. The delay is due to operational inefficiency, excess demand, and unforseen events. Operational inefficiency reduces speed and may cause queue spillovers that reduce exiting flows. Excess demand creates delay on ramps. Unforseen events such as accidents temporarily reduce capacity. The Cell Transmission Model of a freeway w...
متن کاملWhen are Marginal Congestion Tolls Optimal?
Marginal tolls are known to provide the existence of an optimal equilibrium in atomic congestion games, but unlike nonatomic games, there might be additional equilibria even with linear cost functions on resources. In this paper, we show that in games with a large number of players, all equilibria are near-optimal.
