Flictec, Inc., is a Japanese mobile application development company. They have been avid users of our Mobile SDK and the CARTO platform for many years. One of the solutions they provide is an advanced traffic and navigation application 渋滞ナビ or Jyutai Navi (Japanese for traffic jam navigator), with millions of happy end-users you can call it the “Waze of Japan.”
Probe data is collected from users smartphones and recorded into CARTO, so they can get traffic insights by spatially analyzing probe data with road networks. Flictec has been collecting data since 2013 and the total number of collected records has reached more than 10 billion. Currently, they add 30 million records per day that span across Japan. Flictec also keeps all of its data and uses it to predict future traffic jams. Now, they have 8TB in CARTO, making it one of the largest CARTO single database instances. To avoid slowing they do partitioning every 12 hours and use additional databases for map-matching analysis.
Here is real time probe data from Jun 13, 2016 at 8 a.m. to 9 a.m., as recorded in CARTO, for the center of Tokyo:
Each data point indicates location, speed, and bearing. Using CARTO, they’ve plotted the very slowest cars as red, slower cars as orange, faster as blue, and the fastest as green.

This is a very exciting use case for CARTO! Seeing a customer merge our web and mobile technologies, long before we were united, and really stretch our technical limits in several ways, is very inspiring to us. We wish them the very best in their solution and will keep looking for other cases like this!
Happy mobile data mapping!
