The aqueduct model
Figure 12. Artery Area Experiencing a Bottleneck
Figure 13. Best Chain Breadth and Delay
One appliance of the N-curve is the aqueduct model. In a aqueduct model, the accumulative agent calculation is accepted at a point afore the aqueduct (i.e. this is area X1). However, the accumulative agent calculation is not accepted at a point afterwards the aqueduct (i.e. this is area X2), but rather alone the accommodation of the bottleneck, or the acquittal rate, μ, is known. The aqueduct archetypal can be activated to real-world aqueduct situations such as those consistent from a artery architecture botheration or a cartage incident.
Take a artery area area a aqueduct exists such as in Figure 12. At some area X1 afore the bottleneck, the arrivals of cartage chase a approved N-curve. If the aqueduct is absent, again the abandonment amount of cartage at area X2 is about the aforementioned as the accession amount at X1 at some time after (i.e. at time TTFF – free-flow biking time). However, due to the bottleneck, the arrangement at area X2 is now alone able to accept a abandonment amount of μ. Back graphing this scenario, about we accept the aforementioned bearings as in Figure 9: area the accession ambit of cartage is N1, the abandonment ambit of cartage absent the aqueduct is N2, and the bound abandonment ambit of cartage accustomed the aqueduct is N’2. The acquittal amount μ is the abruptness of ambit N’2, and all the aforementioned cartage breeze characteristics as in Figure 11 can be bent from this diagram. The best adjournment and best chain breadth can be begin at a point M on Figure 13 area the abruptness of N2 is the aforementioned as the abruptness of N’2, or in added words back the basic accession amount is according to the acquittal / abandonment amount μ.
Additional uses of the N-curve in the aqueduct archetypal is that it is additionally able to account the allowances in removing the bottleneck, whether in agreement of a accommodation advance or removing an adventure to the ancillary of the roadway.
edit Dynamic cartage assignment
Dynamic cartage appointment can additionally be apparent application the N-curve. There are two capital approaches to accouterment this problem: Arrangement Optimum or User Optimum. This area will be discussed added in the afterward section.
