Passive Sensing of Conductive Concrete for Vehicle Lateral Positioning - Sachindra Dahal

Sachindra Dahal, a Ph.D. student at the University of Illinois at Urbana-Champaign, presents during the 2020 CCAT Poster Competition. Their presentation, Passive Sensing of Conductive Concrete for Vehicle Lateral Positioning, proposes a system of embedded road sensors for lane detection. This would be especially useful in regions that experience inclement weather. Thank you to ITS Michigan for your sponsorship of this student outreach effort. -- Follow us!

Vehicle to infrastructure sensing capabilities are necessary especially during severe weather conditions for significant penetration of Level 4 or 5 AV without compromising safety. Embedding sensors inside concrete and asphalt pavements is the primary way for the existing vehicle technology to communicate with road. Changing local electrical conductance of concrete using steel-fiber and detecting such changes using eddy current technique is proposed for lateral lane positioning of AV. Concrete slab specimen with targeted areas of steel fiber reinforced concrete (SFRC) were tested under normal and adverse surface conditions created by standing water or ice. The longitudinal segment of SFRC material in the concrete was successfully located by the eddy current transmitter coil even under imposed adverse surface condition. This study presents a reliable and robust technique to change concrete’s electrical conductance enabling passive sensing in order to provide lateral positioning of AV both in normal and adverse surface conditions.
