Takanome: Litter Distribution Research

The Image analysis x Smartphone service to keep your city clean.
Understand the current situation, measure the effectiveness of previous methods, and propose better ones, all by visualizing the distribution of litter.

Takanome is a service that visualizes the distribution and severity of litter on streets. 'Takanome for Automobiles' investigates wide areas using vehicles, while 'Takanome for Pedestrians' focuses on specific areas and provides more detailed results. Using such services, users can find out areas where litter tends to gather, and optimize their cleaning strategies to achieve the best results. This includes maximizing the efficiency of local cleaning activities, quantifying the effect of implementations, and etc..

What are the benefits of this service?

Sustainability activities using vehicles.

Around Tokorozawa station in Saitama

With support from Professor IRIE Teruaki, Tokyo University of Agriculture, the distribution of litter around Tokorozawa station was investigated to explore the effects of smoking areas to litter distribution. It is found that after the removal of the smoking area, the amount of littering increased in the nearby park.
