 ### Matrix Road Caster
-
+Matrix Road Caster is a machine learning algorithm used to estimate the average speed on the road links at a given time of the day.
+
+Random origins and destinations are scattered on the network, the Origin-Destination times are requested on the Here API for the chosen time of day
+![alt text](/here/1_HERE_zones_centroids.png)
+The iterative algorithm adjusts the speed on the network and computes the shortest path until the OD times are consistent between the network and the request pool.
+![alt text](/here/2_HERE_iteration_error.png)  ![alt text](/here/3_HERE_road_calibration.png) 
+To calibrate the roads at a small scale with few requests, OD times are interpolated before the iterative OD to road time algorithm.

+The relevancy of the interpolation is monitored
