CiudadSim Examples

We give here a description of the traffic network examples that can be generated by the function TrafficExample of the toolbox CiudadSim. The calling sequence for this function is as follows:

$net={\rm TrafficExample}(name,p1,p2,p3,p4);$

where net is the NetList of the traffic network, name determines the example and p1, p2, p3 and p4 are parameters needed for some examples.
For each example we present here 3 matrices containing its data. The general properties (GP) matrix contains the node number (nn), the links number (ln) and the demand number (dn).
The link performance function data (LPF data) matrix is the 4 x ln matrix

$LPF\; data= \left ( \begin{array}{c} t0\\ ca\\ ma\\ ca\\ \end{array}\right )$

where t0, ca, ma and ba are row vectors, we give the values or the intervals for this parameters.
And finally, the Demands matrix is given by a 3 x dn matrix

$d= \left ( \begin{array}{c} dt\\ dh\\ dv\\ \end{array}\right )$

where dt,dh and dv are the vectors of the demands tail, head and value respectively.
For all the examples, the field time of the corresponding NetList is initialized to be equal to t0, its free flow travel time; after doing an assignment this field represents the real time needed to travel over each link for the given flow. Using the functions ShowNet or ShowLinks we show the graphics of the traffic networks. In the cases where it is possible, we also present the traffic networks obtained after a flow assignment performed using the function TrafficAssig.
