Yokota and Tamagawa focused on another issue: map-matching and route identification [12,13,14]. More precisely, they used dynamic programming to identify the GPS position and match it into a map to reconstruct the routes. The aim of the study is to provide a decision support device to evaluate road network usage by freight distribution vehicles. Moreover, the authors aim to provide a practical method to extract and process GPS data. effectiveness is shown in comprehensive field data tests. A probe survey is made by extracting 27 companies from those participating on a precedent survey in 2005 [12]. More than three million probe data in highest probe density mesh were collected. Almost 270 out of 300 trucks contributed to the probe survey on weekdays (the number decreased on Saturdays, Sundays and holidays).Data was collected each tzo seconds. Yokota and Tamagawa [12,13,14] using dynamicprogramming, a matching algorithm to compare obtained results in terms of route lengths and characteristics, compared to the existing literature mainly to trip diaries results [15]. The proposed algorithm seems to match well the GPS position to the roadmap, but a generalization to other contexts should be carried out.
