This workflow contains a set of Matlab codes and corresponding results of a geospatial dynamic traffic model, and is used by Fung et al (to be published, embargoed until published). The workflow contents are as follows: dynamic_emission_framework.m This is the main script to calculate dynamic emission for the paper 'Scalable geospatial approach for dynamic on-road emission through open-access floating car data' retrieve_API.m This function is to get real-time driving speed and relative speed data from TomTom API read_LCZ_all.m This function is to get local climate zone from a online dataset to our desired spatial resolution class2speed.m This function is to convert color codes from TomTom API to real-world driving speed and congestion level numbers data2emission.m This function calculates traffic emissions from driving speed and congestion levels EF_generator.m This function generates speed-dependent emission factors based on vehicle types (vehicle class anf fuel use), driving speed, etc, using COPERT version 5.7.1: https://copert.emisia.com/wp-content/uploads/2023/09/COPERT-v5.7-Report.pdf spatialagg.m This function resamples spatial data from raw longitude and latitude to desired longitude and latitude Please check the readme.txt for more details on the use of this workflow set. Files Embargoed The files will be made publicly available on January 1, 2025. Reason: The paper where workflow set has been applied is under review. The workflow set will be made publicly accessible until the paper is published.
