In part II of this article, simulation results of the well-known ALINEA method of Papageorgiou et al. It is found that the main aim of ALINEA on-rampintenance of occupancy in free flow downstream of an on-ramp bottleneck inchieved through the usexplained why none of the ALINEA strategies can at the bottleneck. The ALINEA strategies cannot also prevent subsequent continuous upstream congestion propagation. It will also be explained why UP-ALINEA (in thiseam of the bottleneck), which can preventneck, cannot maintain a chosen optimal (target) occupancy in ahbourhood: as a result, the vehicle queue at the light signal in the on-ramp lane(s)art III of this article, a congestedhich can overcome the disadvantages of ALINEA, XALINEA/ strategies as well as of other on-ramp metering strategies in the context of.
