GRID2DEMAND: A tool for generating zone-to-zone travel demand based on grid cells
Introduction
Gird2demand is an open-source trip generation and distribution tool for teaching transportation planning and applications. It generates zone-to-zone travel demand based on alphanumeric grid zones. Users can obtain zone-to-zone and node-to-node travel demand with a few lines of python code based on OpenStreetMap and OSM2GMNS.
Quick Start
Users can refer to the template code and test data set to have a quick start.
Installation
pip install grid2demand
If you meet installation issues, please refer to the user guide for solutions.
Simple Example
import grid2demand as gd
gd.ReadNetworkFiles("./data_folder")
gd.PartitionGrid(number_of_x_blocks=None, number_of_y_blocks=None, cell_width=500, cell_height=500, latitude=30)
gd.GetPoiTripRate(trip_rate_folder = "./data_folder", trip_purpose=1)
gd.GetNodeDemand()
gd.ProduceAccessMatrix(latitude=30,accessibility_folder=None)
gd.RunGravityModel(trip_purpose=1, a=None, b=None, c=None)
gd.GenerateAgentBasedDemand()
Visualization
Open QGIS and add Delimited Text Layer of the output files.
