Abstract

See full text

A particle filter, also known as Sequential Monte Carlo Method, used to estimate vehicle position based on GNSS pseudo range measurements and other sensors. The particle filter creates an ensemble of particles and road user charging (road tolling) can be performed on each particle. The resulting distribution of assessed vehicle passages is analyzed to assess if the event actually took place or not. The use of particle filter overcomes limitations occurring while employing traditional Kalman filter based methods.
