Position accuracy with redundant MEMS IMU for road applications
Traffic problems have mainly resulted from an increase in mobility over the last decades involving an increase in traffic congestion and degradation of environmental conditions. The employment of new systems - namely, Intelligent Transport Systems (ITS) is being considered for their mitigation (1,2). ITS offer a high number of applications providing different types of support to the user: usually the driver or the traveler. These may range from "simple" solutions dedicated to comfort (e.g. parking aid, e-toll) or information services (e.g. navigation, Variable Message Signs) to more complex ones such as Advanced Driver Assistance Systems (ADAS). One may distinguish pre-crash ADAS (e.g. collision warning, lane warning), post-crash ADAS (e-call) and fully automatic driving systems like Automated Highway Systems (AHS). The complexity is characterized through the maturity level and market distribution.
