Digital Twin Technology Applications For Transportation Infrastructure - A Survey-Based Study

In the past couple of decades, various industries have taken advantage of emerging advanced technologies, such as digital twin (DT), to find more effective solutions in their respective areas. In the transportation infrastructure sector, the concept and implementation of DT technologies are slowly gaining traction but lagging behind other major industries. To better understand the limitations, opportunities and challenges for the adoption of DT in this sector, a survey questionnaire was distributed to collect information from industry professionals involved in transportation infrastructure projects. The purpose of this study is to understand how DT technology is being perceived by the industry. Based on the results of this survey, the current state of DT in the infrastructure sector, as well as the expected benefits, and potential challenges for the deployment of DT are discussed here. This study aims to initiate discussion for future research in DT technologies for transportation infrastructure applications
