Effects of HOV Lanes on Freeway Bottlenecks

In this paper, the authors report on research that shows that high occupancy vehicle (HOV) lanes do not reduce the capacity of general purpose (GP) lanes. Empirical evidence, complemented with simulations, enable the authors to describe how to estimate total bottneleck capacity and how deploy HOV lanes without hindering vehicle flow. The authors also offer a dynamic strategy that increases a bottleneck's total discharge rate.
