**Abstract**

This article focuses on the cybersecurity issues of intersection management—an element of transportation management systems—for local governments. Until relatively recently, concerns about and research needs for intersection cybersecurity have been largely ignored, and local governments have focused on other types of cyber threats, relying instead on private sector vendors to provide equipment that is safe against attacks. To address the gap in the literature, this article provides a short overview of the types of components used in intelligent transportation systems (ITS) and reviews the critical issues for local governments. Further, it discusses some current efforts to remediate the vulnerabilities in ITS and examines the current regulatory framework. This review of the issues is augmented by an analysis of local government perspectives using the Delphi method. The article concludes with some recommendations.
