Introduction

This is an introduction about a unified and validated traffic dataset for 20 U.S. cities. The input data were all collected and processed from multi-source open public datasets. We applied two traffic modelling platforms (TransCAD and AequilibraE) simultaneously to obtain the final results.

About the dataset

Data contents

• 01 Input data

  • the initial network data obtained from OpenStreetMap (OSM)
  • the visualization of the OSM data
  • processed node/link/od data

  A brief demonstration about the input data is provided here.

• 02 TransCAD results (software version: 9.0)

  • cityname.dbd : geographical network database of the city supported by TransCAD (version 9.0)
  • cityname_link.shp / cityname_node.shp : network data supported by GIS software, which can be imported into TransCAD manually. Then the corresponding '.dbd' file can be generated for TransCAD with a lower version than 9.0
  • od.mtx : OD matrix supported by TransCAD
  • LinkFlows.bin / LinkFlows.csv : traffic assignment results by TransCAD
  • ShortestPath.mtx / ue_travel_time.csv : the travel time (min) between OD pairs by TransCAD

  A guide for TransCAD users who want to get access to the results is provided here.

• 03 AequilibraE results (software version: 0.9.3)

  • cityname.shp : shapefile network data of the city support by QGIS or other GIS software
  • od_demand.aem : OD matrix supported by AequilibraE
  • network.csv : the network file uesed for traffic assignment in AequilibraE
  • assignment_result.csv : traffic assignment results by AequilibraE

  A python code file for AequilibraE users who want to get access to the results is provided here.
