net2grid: An open-source academic research tool for building macro GMNS networks from micro GMNS networks for transportation system modeling and optimization

Requirements

• shapely

Simple Example

The recommended way to install use the package is colning the source code from github.

>>>import net2grid as ng

"""Step 1: Read GMNS network"""
net=ng.read_gmns_network_from_csv('./data')

"""Step 2: Build macro GMNS network"""
# set the number of grids to build a macro GMNS network
ng.partition_grid(net,n_grids=(100,100))
# or set the size of grids to build a macro GMNS network
# ng.partition_grid(net,s_grids=(0.005,0.005))

"""Step 3: Save network files"""
ng.save_network(net,output_folder='./macro_network_by_n_grids')
