A Reformulation of the Theory of Optimal Congestion Taxes
Key Points
The aim is to refine the understanding of congestion by focusing on vehicle counts instead of traffic flow.
Analyzed variations in congestion over short durations
Proposed estimating congestion using the number of vehicles
Compared traditional traffic flow measurements with new vehicle count approach
Found that vehicle count provides a more accurate picture of congestion
Demonstrated practical implications for optimal congestion tax design
Abstract
The author suggests that congestion varies over short periods. It should be estimated from the number of vehicles on the road, rather than from the flow of traffic.
