I am studying at the minimum number of shared autonomous vehicles would need to meet all traffic demand of motor vehicles needs for a city, and considering the impact of joining rail transit to further optimize fleet size. I plan to cite the paper titled "Addressing the minimum fleet problem in on-demand urban mobility" in my paper, and compare the method of solving the minimum fleet size in this paper with my research method, so as to prove whether my research is effective. Therefore, I would like to ask if you have the source code for this article. If so, please contact me at [email protected]. Thank you very much!
