Integration of traffic and structural health monitoring on the Varina-Enon Bridge via sensor fusion

项目名称：	Integration of traffic and structural health monitoring on the Varina-Enon Bridge via sensor fusion
摘要：	The significance of this study is two-fold. Firstly, it will demonstrate an application-centric example of ITS and SHM integration. According to a review on ITS and SHM integration by Khan et al. [4], few examples exist in the literature which relate to the estimation of structural features. These types of applied studies are important to establish credibility in these techniques as solutions to practical problems. Secondly, through data fusion techniques, the study will explore alternative sensing methods to complement camera-based measurements, which can suffer from poor performance at night or during inclement weather. A subset of ITS systems, called Bridge-Weigh-InMotion (BWIM) systems, have been developed over several decades to estimate number of axles and vehicle weight using only contact sensors (no cameras). However, positional tracking and vehicle classification has not traditionally been part of the BWIM approach. Furthermore, weight estimation of vehicles on long bridges like the Varina-Enon has not been commonly studied for BWIM [3]. The use of complementary ITS methodologies is a key feature of this study, intended to improve the long-term reliability of these systems. ITS and SHM systems have the potential to save highway infrastructure managers millions in traffic control and maintenance operations, respectively. However, implementation of these systems individually by industry has been slow [4]. The integration of the two systems is more attractive to practitioners because it brings improved performance at a lower cost. That is, on one hand, ITS can make SHM estimates more accurate by providing load information. On the other hand, SHM can complement ITS data to help estimate vehicle weights and overcome
