The Optimal Sampling Period of a Fingerprint Positioning Algorithm for Vehicle Speed Estimation

Table 11

Cost for Cases 1 and 2.

Sampling period (sec)	Free flow (count/hr)	Traffic congestion (count/hr)
1	132	458
20	85	329
41.589	54	214
60	35	147
80	22	83
100	20	53
120	9	39

Bold values refer that the optimal sampling period was 41.589 s. And we explain in Section 4.2.5.
