Abstract
Method and device for real-time error bounded and relay bounded map matching. The method for map matching comprises of modelling each road arc as a hidden state and each location measurement as an observation emitted by the hidden state using a Hidden Markov Model, decoding each road arc and each location measurement using a Viterbi algorithm and outputting a matching road arc, wherein the outputting is delayed by a delay time in response to an optimal trade-off between selection accuracy and selection latency.
