Due to the worldwide outbreak of the pandemic covid-19, 2020 4th International Conference on Intelligent Traffic and Transportation has been changed to a virtual conference instead of being held physically as planned in Paris, France. The participants all showed their support and understanding in such situation, who have joined the conference and presented their papers online using Zoom. On behalf of the organizing committee, we'd like to thank all the keynote speakers, invited speakers and authors. We believe we'll all survive this health crisis and get back to our normal life soon. We look forward to seeing you all next year.
Accepted and registered papers of ICCNT 2020 will be published here: http://www.jocm.us/list-234-1.html
