Vehicular Traffic

The theory of conservation laws was applied to vehicular traffic modeling. For traffic at junctions the following two rules were used to define a unique solution:

(A) fluxes distribute on outgoing roads according to fixed coefficients;

(B) the through flux is maximized (respecting rule (A)).

The first rule expresses driver preferences, while the second one is an ”entropy” type condition. 

A number of different transportation problems were considered as:

a) Traffic monitoring and GPS data (Rec. papers: 2, Other papers: 1,2).

b) DTA (Rec. paper: 1).

c) Traffic signals (Rec. papers: 4, Other papers: 5).

d) Moving bottlenecks (Rec. papers: 7).
