Abstract (in Japanese) (See Japanese page) 
(in English) We propose a multi-agent based interpolation system of traffic condition, which includes estimation and learning agents. These agents are allocated to all the road links. Estimation agents renew the velocity of each road link, and learning agents renew the weight values for estimation. Estimation and learning agents alternately calculate the results to improve the interpolation accuracy. The standard deviation of the estimated velocity is 8.53 km/h, which is obtained from the probe car data from 2007/11/01 to 2008/10/31.
