BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:
@booklet{EasyChair:10567,
author = {Zuo Huang and Richard O. Sinnott and Kris Ehinger},
title = {Truck Speed Detection Through Video Streams},
howpublished = {EasyChair Preprint 10567},
year = {EasyChair, 2023}}
