The setting in the public ramp management is controversial. On the one side are the low cost and the perceived benefits for the traffic on the highway. On the one hand the disadvantages adopted for the traffic on the ramp and in the subsequent subordinate road network are highly weighted. Questions arise as to the proportionality.

Number of sections of highways is prone to faults and they suffer from breakdowns of traffic flow. The consequences are accidents, delays, air pollutant loads and thus economic losses.
With the expansion of the transport infrastructure alone these traffic problems cannot solve today. The road network is to be managed, so that mobility is ensured, is low in emissions and remains safe. A cost-effective way to improve traffic flow on motorways is the ramp management. However, the reflections on the meaning, purpose and method of ramp management must not be limited at certain points to the vulnerability of the highway and on the ramp, but it should be considered a corridor, which also includes the subsequent subordinate road network.
