Route coupling

This script calculates the coupling of routes in a instance of the route choice problem.

Requirements

There is the need to initialize the submodules, to do so use the following command:

git submodule init && git submodule update

Usage

to calculate the coupling, use the couplin2.py script it has the following parameters:

-nf: the network file

-rf: the route file (one of these two must be provided. if both are, the route file will be used)

-sf: the simulation output file

-k: parameter for ksp

example:

python coupling2.py -nf networks/OW.net -k 8

Route Files

Instead of calculating the routes at each execution, one can pre-process a network file with the goal of generating a route file. To do this simply execute the command below. K is the number of routes to calculate for each OD pair.

calculateRoutes.py inputnet k outputfile

Output

the output will be in the form of a csv file in the folder from which the code was ran.

The outuput format is as follows:

Route CouplingHop CouplingFFTT
10|1(1) 2.60478332939 2.56208196333

CouplingHop indicates the non-weighted coupling metric. i.e. all edges have the same weigth.

CouplingFFTT indicates the weighted coupling metric using the free flow travel time of each edge as its weight.
