The Ultra Portable Ride Quality Meter (UPRQM) is a cost-effective, flexible tool that can evolve (with minimal effort) as new GPS and accelerometer devices become commercially available. Each generation of these sensor devices is more responsive, more sensitive, and more accurate than the last generation. The time between generations is also decreasing such that accelerometer and GPS technology ...

During Phase 1 of the project, Sharma & Associates, Inc. developed a concept for high speed freight truck intended for 70-ton, regular freight and bi-modal operation, at speeds up to 150 mph. The truck uses a rigid frame and an indpendent, compliant, primary suspension for its basic architecture. Constant contact side-bearings and yaw dampers were also added to improve dynamic performance. Vehi ...

The goal of this project is to develop, prototype, and experimentally validate a new Differential Global Navigation Satellite System (DGNSS) capable of providing sub-centimeter positioning accuracy for quasi-static scientific, survey, and structural health monitoring application. The main feature of the proposed DGNSS solution is that it leverages publically available GNSS reference data from exis ...

NanoSonic will work with the Giles County School System and Leidos transportation engineers to develop STEM lesson plans concerning ITS and CV technologies, and will demonstrate their use in the classroom with Middle School and High School teachers and students. During Phase I, twenty draft lesson plans were developed, ten for Middle School and ten for High School. During Phase II, these plans w ...

This effort is advancing the development of a nondestructive evaluation (NDE) tool for quantitative assessment of highway bridge coatings, the Infrared Coating Inspection System (IR‐CIS). The IR‐CIS can be used to improve decision‐making regarding over‐coating or recoating of bridges, by better and more fully quantifying the current condition of coatings in ways not possible using only vis ...
