“…Qiao et al proposed an RFID-based smart guide sign system (15) and conducted field tests on the working range of RFID tags in front of stop signs (16). However, there were no detailed reports or analyses of how this system would affect vehicle trajectory, speed, and acceleration; therefore, the relevant impacts on safety and air quality were unknown.…”

A work zone is an area of roadway with construction, maintenance, or utility work activities. According to NHTSA, many traffic accidents and fatalities happen in work zones. Many traditional safety countermeasures have been utilized in work zones, including installing special signs and barriers and posting suitable speed limits. However, these measures have not fully solved the problem. Radio frequency identification (RFID) is a powerful, globally accepted technology that has had great success in business management for decades and can be employed as an advisory device that communicates between vehicles and infrastructure in work zones. The purpose of this study was to develop an RFID-based driver smart assistance system (DSAS) to improve traffic safety and air quality in work zones. The RFID device enabled communication between the vehicle and the roadside on a real-time basis and was supplemented with GPS and other sensors for dynamic traffic management. Such an assistance system would provide suitable verbal and visual warning messages to drivers approaching a work zone. Road tests with the DSAS were conducted in Houston, Texas, with 20 drivers, and the system's impact on vehicle speeds, safety, and vehicle emissions was examined. Statistical results from the tests showed that the DSAS helped drivers take action earlier to decelerate and reduce speeds. All test subjects evaluated the system as satisfactory. This system can also help to reduce most types of vehicle emissions. Further testing and improving of this promising system is recommended in broader fields.
