Abstract
To control the traffic flows near on-ramps and off-ramps, ramp metering
installations can be used. We compare on-ramp metering and off-ramp metering,
with respect to queue forming and total time spent. Both control measures are
used to improve traffic flow on freeways, and both have influence on the route
choice of the drivers. Although the two measures are very similar, there are
some major differences. The use of ramp metering installations can change the
traffic assignment in the network because the inflows or outflows of the
freeways are limited. This will result in a change in travel times in the
network. And since drivers make a route choice based on these travel times, the
route choice (and thus the traffic assignment) can change as well. This can
lead to a relocation of queues in the network. With a case study we illustrate
the differences between on-ramp and off-ramp metering, with three different
control methods: fixed time control, ALINEA and a model predictive
control-based method.
