The bottleneck model of congestion with endogenous scheduling has become a standard tool of transportation economics …. It provides surprising insights about the time pattern of congestion, optimal pricing, and many distinct inefficiencies …-time reliability, traffic information, and extreme congestion ("hypercongestion"). It has been developed for use in practical network …

This paper considers a congested bottleneck. A fast lane reserves a more than proportional share of capacity to a … the bottleneck and inelastic demand. It can replicate the arrival schedule and queueing outcomes of a toll that optimally …
