The goals have been largely accomplished and a peer-reviewed paper has been published in the Transportation Research Record. The project has supported the professional development of the 5 graduate students listed as coauthors. One has gone on to work on traffic papers for the City of Philadelphia, whose transportation staff supported the project. The results have been disseminated through conference presentations, a publication, and safety reports of the city of Philadelphia. During the next reporting period, we will continue to disseminate results. We will also collect additional data and work with city staff on the identification and study of 5 additional segments and 5 additional zones that are being considered for automated speeding enforcement in Philadelphia. Impacts The results of the study have supported work that contributed to the state legislature voting in December 2023 to allow expansion of the automated enforcement program to five additional corridors and five school zones. The study also provided insight into studying the effects of automated enforcement on single corridors during periods of substantial change in traffic safety outcomes.
