Codes and results for the paper 'Scalable geospatial approach for dynamic on-road emission through open-access floating car data'

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
