Work Zone Performance Monitoring Application DevelopmentAuthor/Presenter: Sadabadi, Kaveh Farokhi; Pack, Michael L.; Ivanov, Nikola; Jacobs, Thomas H.
The Federal Highway Administration (FHWA) requires state transportation agencies to (a) collect and analyze safety and mobility data to manage the work zone impacts of individual projects during construction and (b) improve overall agency processes and procedures related to work zone safety and mobility. To help achieve these goals, the University of Maryland, in partnership with Maryland State Highway Administration (SHA) and FHWA, developed a Work Zone Performance Monitoring Application (WZPMA) that uses third party probe data for real-time monitoring and evaluation of work zones. The WZPMA was included as a tool within the Regional Integrated Transportation Information System (RITIS). This report provides an overview of the WZPMA as well as methodology used to compute various work zone performance measures. Example applications of the WZPMA are also provided.
