GRID2DEMAND: A tool for generating zone-to-zone travel demand based on grid zones

Introduction

GRID2DEMAND is a quick trip generation and distribution tool based on the four-step travel model. First, the research region is divided into grid zones of the same scale. POI nodes are used to generate node production/attraction. Second, trip distribution is achieved by a typical gravity model.

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.readNetworkFile("./data_folder")
gd.NetworkPartition(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.
