Probing a traffic congestion controversy : density and flow scrutinized

Auteur :
OHTA, H.

Description :
Optimization requires equilibrium flow to decrease under mild congestion, but increase under hypercongestion. However, both increasing flow needed under hypercongestion and decreasing flow needed under mild congestion should be accompanied by decreasing density. Thus, inflow of vehicles should always be discouraged to either increase or decrease flow of vehicles for economic efficiency. Moreover, even when optimal policy requires equilibrium flow to increase, the optimal flow itself must decrease eventually as demand increases beyond a critical level.
